WORKSHOP 1
Balancing Science and Service in a SRL​


Facilitators: Joanne Lannigan and Rui Gardner

Overview:
The mission of SRLs is to provide key technological services to researchers/investigators, as well as provide guidance and expertise on the use of such services in scientific investigations. A major role of SRLs is to also insure quality data which is reproducible. However, another very important role of the SRL is to be on the forefront of new technologies and their applications, as well as the development of new applications and tools to enhance an investigator's resources for discovery. While one may think these roles should be complimentary, often due to time, staff and other resource limitations, they may be competitive and in conflict. This workshop will involve small working groups (5-7 people) assigned key questions to discuss. The results of such discussions will be shared with the entire group. The following key questions will be addressed in this workshop:

What are the benefits/penalties of having both science and service activities within a core?
Where do resources to perform the science part come from?
Who pays for the component of staff salaries dedicated to research? 
How can SRL personnel balance the need for both science and service?
Should everyone be involved in science and service or should there be dedicated individuals for each? 
How do you allocate time and priorities for each of these activities?

Agenda:
Introduction (30 minutes): Joanne Lannigan & Rui Gardner

Small Group Discussion (30 minutes): All participants

Small Group Summaries (20 minutes): Small Group Facilitator

Workshop summary and conclusions (10 minutes): Joanne Lannigan and Rui Gardner

WORKSHOP 2
A Successful Imaging Flow Cytometry Facility: Guidelines for Management and Publication


Facilitators: Dominic Jenner, Ziv Porat, and Aja Rieger

Overview:
Imaging flow cytometry (IFC) is a main stream technology being utilised worldwide to great effect. However, there are still obstacles in the way between the acquisition of an imaging flow cytometer and its successful integration in a flow core or Scientific Research Laboratory (SRL). In this workshop we aim to discuss and put together guidelines for the best ways to manage your IFC equipment within a flow core or SRL. In addition the guidance on the best practice for publishing imaging flow cytometry data is still lacking and MIFlowCyt guidelines for the publication of imaging flow cytometry data would be of great benefit to the community. In this workshop we aim to discuss both of these topics and gather the thoughts of the IFC community.

Agenda:
The workshop will be split into three sections:

Introduction (5 minutes):

Discussion theme 1 (30 minutes): How to run an IFC in an SRL?
a.    How best to train staff/users to run samples
b.    Best ways to train staff and/or users to analyse samples
c.    How best to retain the analysis capability with staff turnover
d.    The most appropriate people to perform IFC analysis e.g. Researcher or SRL staff
e.    User management (advertising, recruiting users, follow-up and maintaining users, contact with PIs, academic credit)

Discussion theme 2 (30 minutes): Guidelines for publication of IFC data. There is some guidance (Filby et al) on publishing IFC data, but no solid guidelines. These can include: instrument setup, acquisition details, gating strategy, full description and justification for the masks and features used, 

Discussion theme 3 (20 minutes): Open Q&A. 
If you have any questions for the open session please email them to any one of the workshop organisers or post them on the IFC google plus community.

WORKSHOP 3
Dr. Reproducibility or How I Learned to Stop Worrying and Love Validation


Facilitators: Steven Eck, Chris Groves, Jennifer Stewart, and Cherie Green

Overview:
A practical discussion for basic, clinical and translational researchers to explore validation for flow cytometry assays and ask if such testing should be part of publication expectations?  If not, why not?  If so, what data should be provided for which kinds of assays?

WORKSHOP 4
Cytometer Setup, Characterization and Standardization


Facilitators: Toralf Kaiser, Konrad von Volkmann, and Claudia Giesecke

Overview:
We propose a workshop in which standard (bead based) methods as well as a LED (quantiFlash) based method shall be discussed for cytometer setup and standardization. In line, we would like to talk about basics on signal processing and initiate the discussion on determination and technical terms for noise and background as this would be very helpful to distinguish both precisely from target signals.

Agenda:
a)  Bead based cytometer setup / Interpretation of Q and b values
b)  PMT gain range SNR and DNR curves for cytometer setup
c)  Determination of the instrument operation point
d)  General conceptions of functioning of a PMT & signal processing
e)  Discuss the introduction of unequivocal technical terms for instrument characterization (noise, background, dynamic range (DNR), signal-to-noise (SNR))

WORKSHOP 5
Identification of Areas Where Software Tools can Contribute to the Successful Operation of a Shared Resource Laboratory


Facilitators: Gert Van Isterdael, Michael Gregory, Cláudia Bispo, Christian Kukat, Gelo Victoriano Dela Cruz, Diana L. Bonilla Escobar

Overview:
The primary goal of this workshop is to identify areas where implementation of software tools will help contribute to the successful operation of SRLs. To accomplish this we will poll the SRL community on which new software tools they would like to see developed in the future to make the operations of the facility more comfortable and efficient and to discuss software solutions that SRLs are currently using and how they might be improved.

Agenda:
(15 min) Presentation about the goal of the workshop
(15 min) Show results of the user survey (Purdue list and Google+ Cytometry Forum)
(30 min) Dividing the attendees in sub groups for focussed discussions:
1) Identifying areas where software could help within the SRL
2) Discuss existing software solutions for specific questions e.g. Quality control, scheduling, project management, communication to users
3) New tools (or addons to existing software) that the SRL community would like to see being developed

(30min) Make a recap of group discussions and final discussion

WORKSHOP 8
Aptamers  in Cytometry

Facilitator: Henning Ulrich

Overview:
This workshop shall introduce researchers and students into the development of fluorescence labeled aptamers for specific cell type detection (stem or cancer cells or parasites) by flow and tissue cytometry. Aptamers are developed by in vitro selection and provide high-affinity ligands with similar binding characteristics as monoclonal antibodies. Aptamers are promising candidates for cytometry, due to their small molecules character and structural flexibility, easily accessing even hidden binding sites. Further, aptamers are synthetic compounds, synthesized at low costs without any activity variations between lots, and easily fluorescence-tagged.

Agenda:
90 min total
Teaching in an interactive way with the audience 
•    Problem Focus and Key Questions: Synthetic ligand (aptamer) selection and fluorescence labeling for specific cell phenotype targeting (20 min)
• Technical aspects and innovation, fluorescence tagging; chemical modification for enhancing stability and selectivity of aptamers (15 min) 
•Applications for flow and imaging cytometry; novel protocols and assays for epitope detection for stem and cancer cell identification as well as parasite detection (15 min)  
•Comparison com features of antibodies (i.e. mesenchymal stem cell detection by CD29, CD90 and CD105: multipanel antibody detection vs. using a single aptamer for detection). Easy labeling of aptamers for flow and imaging cytometry (10 min) 
•    Interactive discussion of technical points and responding  to the questions of the audience  (30 min)
- Protocols for aptamer development, including reagents (random templates, primers, fluorescence labeling, polymerases, target cells and their preparation), amplification steps, selection and affinity determination by flow cytometry  
-To understand flow cytometry and cell sorting using aptamers as fluorescent ligands: Mesenchymal stem cells can be identified and sorted  from a heterogeneous mixture of cells. 
- To be introduced to labelling of live cells using fluorescent aptamers: binding reversal with DNA nucleases
- Knowledge on Specific applications: - Aptamer kits for cell isolation and flow cytometry
- Explanation for which application aptamers would be advantageous over antibodies: Detect not easy accessible targets; a second oligonucleotide can be used for increasing target-binding versus noise ratio. Aptamers can denatured and renatured (different from antibodies)
- Discussion of reagent selection and validation for cytometry (aptamers and antibodies)

WORKSHOP 10
Best Practices for Development and Implementation of Automated, Standardized Multiparameter CyTOF Panels


Facilitators: Radhika Rayanki, Chris Groves, Thomas Ashhurst, and Nicole Paul

For the survey associated with this workshop, please click here.

Overview:
Mass cytometry promises to be a potential game changing technology that provides unmatched depth of immune system characterization at the single cell level. The method dramatically expands the capability of cell subset identification and phenotype compared to flow cytometry (FCM). The use of rare-earth metal isotopes conjugated to monoclonal antibodies to evaluate multiple parameters simultaneously on individual cells is measured with minimal overlap between channels. The difficulties in this platform typically concern (1) ease-of-use (2) high cost (3) creation of large panels (4) data analysis and visualization, all of which can be limiting factors or roadblocks to the wide spread implementation and use of this technology compared to flow cytometry.

Format/Agenda:

The format will include a discussion of the results of pre-conference survey on what SRL (Shared Resources Laboratories) are currently doing. There will be an “open mic” session where attendees will be encouraged to bring information to share on situations/mistakes/troubleshoot/success & failures/challenges for clinical validation studies. This will be followed by a few brief presentations that are composed of:

1. Ease of use: Methods optimization and reagent testing for environmental contaminants and rigorous instrument setup and performance testing
2. Cost savings: Assay miniaturization and Reagent management techniques are critical for CyTOF assay optimization
3. Automated Robotic cocktailing for panels to increase capacity and reduce variability help move quickly to identify problems
4. Data analysis and visualization methods are questionable given variability in results generated by clustering algorithms
5. Discussion and conclusion with audience participation and feedback

Workshop 11
Flow Cytometry Application in Multi-Center Global Clinical Studies: The Importance of Standardization and Harmonization. Is the Quality of Data Only as Good as the Weakest Control Planned?


Facilitators: Kamila Czechowska, Alessandra Vitaliti, Attila Tarnok, David Lanham, Ryan Brinkman, Paul Trampont

Overview:
Flow cytometry is a powerful analytical tool in drug development, and supports a number of areas including drug-target engagement analysis and pharmacodynamic biomarker assessments, covering a wide range of end use applications, from basic biology and exploratory endpoints to critical safety and efficacy decisions. Following the steps of flow cytometry assay development and validation, outlined in international guidelines and white papers, these methods can be implemented in clinical studies.
Testing of patient samples require special measures to ensure high quality standards, due to sample instability and limited availability of reference materials. This presents challenges in multi-center global studies. The collaboration between the clinical and analytical teams, process harmonization/standardization, from sample collection to data reporting, are the foundations for success and the generation of robust and reliable results for decision making conclusions. In this respect - the assurance of result quality is strengthened in analytical laboratories that follow regulations such as those from the Good Clinical Practice (GCP), College of American Pathologist (CAP), International Organization for Standardization (ISO), or the Clinical Laboratory Improvement Amendments (CLIA).
 
In this workshop, we will present and discuss key aspects critical to achieving standardization and harmonization of flow cytometry applications in multi-center clinical studies.
 
This workshop is intended to target attendees who are currently involved in, or considering implementing, sophisticated flow-cytometry based assays in multi-site clinical testing for global clinical trials in regulated laboratories. The discussion will also be of interest of young scientists from academia, and to manufacturers of the flow cytometric controls/reagents and analysis software, and will expose participants to current challenges and solutions in this area. 

The scope of this workshop will be to address the following questions:

1. Considerations for specimen selection - based on clinical settings and marker stability assessed during method development  Presenter Alessandra Vitaliti

2. What are the challenges and opportunities of local vs centralized analysis? Presenter David Lanham

3. What are the critical steps that one should take in order to assure processes harmonization and instrument standardization? Presenter  Kamila Czechowska-Kusio

4. What are the controls and how can be introduced in multi-site clinical sample testing? (e.g., what calibrators or controls do attendees use: fresh-, stabilized-, dried-, lyophilized- cells? Beads? How reagents can be managed (importance in long-term studies)? Presenter Attila Tarnok

5. How can we standardize data analysis? (manually-multianalyst or centralized?, automated algorithm based gating?) Presenter Ryan Brinkman

Agenda:
Several of weeks prior to the conference, recipients of the Purdue mailing list will receive an email with the link for online answering of the set of questions. At the beginning of the workshop, the participants  will be asked to choose or give answers to the questions listed above, after which, each co-author of this workshop will briefly introduce the subject (each participant will present 3 slides, time predicted 15 minutes in total). Before the end of the workshop the query will be repeated.

To maximize the number of answers, we will use the CYTO 2018 mobile application in order to gather the answers to our questions from the Congress participants.

The outcomes of the brainstorming at the workshop, final conclusions, the results of the mobile application survey as well as results obtained from the pre-Congress voting will be gathered, analyzed and published in the Cytometry part A and/or on the ISAC website.

Workshop 14
Photobleaching and Phototoxicity in Live Cell Imaging​


Facilitators: Jaroslav Icha, Silas Leavesley, and Rachel Errington

Overview:

This aim of the workshop is to discuss and agree on general guidelines for treating phototoxicity in fluorescence microscopy. We will address questions like what is the level of awareness of the challenges associated with phototoxicity in ISAC, how many ISAC members would benefit from further content on phototoxicity? What are the barriers to adopting best practices against phototoxicity (instrumentation, time, experimental protocol)?

Agenda:
The workshop will start with a 20-minute overview talk by Jaroslav Icha. This will summarize the current understanding of phototoxicity, the methods of its characterization and mitigation. The talk will be followed by questions arising from the presentation and by an active outreach to gain feedback from the audience. We will learn how many within the society are pursuing live cell imaging and of those how many consider the challenges associated with phototoxicity. We will then pursue a discussion on defining the best experimental practices for live cell fluorescence microscopy. This discussion will draw from the talk, the questions asked, the feedback from the audience. The discussion will be moderated and facilitated by Silas Leavesley and Jakub Nedbal.

Workshop 15
Cytometric Fingerprinting for Routine Diagnostics of Microbiome Dynamics in Medical and Environmental Settings


Facilitators: Hyun-Dong Chang, Jakob Zimmerman, Frederik Hammes, Susann Müller, Peter Rubbens, Ruben Props, Frederiek - Maarten Kerckhof

For more information about this workshop, click here

Overview:
Microbiomes perform essential services, ranging from the human microbiome to man-made and natural ecosystems. Human microbiome dysbiosis can be indicative of the host health status, while environmental microbiome changes can impact global biogeochemical cycling, which is intricately linked with climate change.

Agenda:
-17:10-17:15 Part 1: Set-up and standardized methods for microbial community flow cytometry (MCFC) – Hyun-Dong Chang
Many methods exist for differentiation of microbial cell types by fluorescent dyes ranging from the whole microbiome to specific functional or phylogenetic groups. Standardization of measurements is an essential issue here.  This involves decisions on cytometer setup but also automation for fast response assessment of microbial communities.
-17:15-17:25 Discussion pt. 1
-17:25-17:30: Part 2: Screening microbiomes in human environments- Jakob Zimmerman
In a real world example, we will show how flow cytometry and cell sorting in conjunction with gnotobiotic mouse models were relevant to microbiome research.
-17:30-17:40 Discussion pt. 2
-17:40-17:45 Part 3: Complementarity of MCFC in combination with other 'omics'-approaches – Ruben Props
To increase the (phylo)genomic resolution of MCFC, it can be used in tandem with “-omics” approaches. Current challenges and opportunities of integrating MCFC with “omics” will be discussed (with a specific focus on cell sorting).
-17:45-17:55 Discussion pt. 3
-17:55-18:00 Part 4: Ecological measures derived from flow cytometric fingerprinting (FCFP) – Susann Müller
MCFC single-cell data can be evaluated using macro-ecological concepts in an intuitive and actionable way. These ecological metrics can be of interest for both medical and environmental applications. The high temporal sample densities provide new insight into the ecology of microbiomes and may also lead to strategies for microbiome based health management.
-18:00-18:10 Discussion pt. 4
-18:10-18:15 Part 5: Computational challenges for FCFP – Peter Rubbens
The analysis of FCFPs requires high-dimensional multivariate analysis techniques. In addition, temporal aspects need to be addressed, as routine diagnostics require on-line measurement. Therefore, FCFP faces computational challenges, which will be highlighted in this workshop, followed by possible strategies to resolve them.
-18:15-18:25 Discussion pt. 5 and Concluding remarks + data challenge

Workshop 17
A New Solution to an Old Problem: Key Performance and Delivery Indicators (KPIs and KDIs) for a Research Technology Platform (RTP) as a Sustainable Enterprise

Facilitators: Michael Thomson, Andrew Filby, Reiner Schulte, and Anna Petrunkina

For the survey associated with this workshop, click here.

Overview:
Research Technology Platforms (RTPs) and SRLs facilitate the application and utilisation of specific analytical technologies to the highest possible standard thus delivering reputable data across a broad spectrum of research themes.  The broad variation in specialism, institutional policies, needs of users and operational models does not only make the benchmarking and performance monitoring virtually impossible, it also affects the prospects of becoming a sustainable enterprise. An important aspect of sustainability is defined by the staffing of the SRLs/RTPs. In this workshop we would like to review current practices and initiate a discussion focused on how to describe a set of customisable KPIs for a flow cytometry-focused RTP service (FCM-RTP), with the ultimate goal of optimising the performance thus making it sustainable and competitive.  This should allow for benchmarking across the full breadth of RTPs, extending beyond the particular science specialism, demands of the users and institutional/overarching policies.

Agenda:
Following questions will be discussed
1. How is the performance of a FCM-RTP currently measured?
2. How should a FCM-RTP performance be measured?
3. What are the variable that affect this?
4. How can these be measured and thus optimised/reassessed?
5. Could these KPIs be used to set true customisable performance benchmarks?
6.  How to select the right staff for the needs of particular SRL  with respect to the desired education level and ongoing responsibilities
7. Determining Staffing Levels
8. How to make a case for funding for staffing
