Computational Cytometry Summer School

Computational Cytometry Summer School | from Flow Cytometry to Cytomics | Scoop.it
The amount of data collected with cytometers keeps increasing. With studies measuring up to 40 markers, millions of cells per sample and up to thousands of samples, manual gating of all this data becomes infeasible. In this summer school, we will have workshops on all steps of a computational cytometry pipeline in R. On Monday morning, we offer two tracks, one for people with a cytometry background and one for people with a computational background. From Monday afternoon onwards, we will dive into the computational cytometry specifics. We will cover data cleaning, cell population identification and downstream statistics.  In addition, we will also have some sessions where these concepts are demonstrated on commercial platforms, such as FlowJo, FCSExpress and OMIQ.

Frontiers | Flow cytometric analysis of innate lymphoid cells: challenges and solutions

Frontiers | Flow cytometric analysis of innate lymphoid cells: challenges and solutions | from Flow Cytometry to Cytomics | Scoop.it
IntroductionThe three groups of helper innate lymphoid cells (ILCs), namely ILC1, ILC2 and ILC3, have been identified by flow cytometry by combinations of cell surface markers. Here, we review various ways ILCs are currently identified, focusing on potential problems and their solutions. The first step to identify all ILCs is to exclude other lymphocytes and myeloid cells by their lineage-specific markers (Lin). However, the Lin cocktail varies in various studies, and the definition of Lin- population containing ILCs is often ambiguous, resulting in contamination of Lin+ cells, particularly T cells.MethodWe have designed combinations of cell surface markers to identify ILC populations in various tissues of B6 mice by flow cytometry. To minimize T cell contamination, TCR/CD3ϵ antibodies were used separately from the Lin cocktail. ILCs identified by surface markers are confirmed by the expression of the transcription factors GATA3, RORγt, T-bet and Eomes.ResultILC1s in the B6 mouse liver are identified by Lin-NKp46+NK1.1+TCR/CD3ϵ−CD49a+CD49b−. However, defining ILC1s in other tissues remains a challenge. ILC2s in the lung are identified by Lin−TCR/CD3ϵ− Thy1+CD127+ST2+ whereas ILC2s in the small intestine and liver are identified by Lin−TCR/CD3ϵ−Thy1+GATA3+RORγt−. ILC3s in B6 mouse spleen, liver, lung and small intestine are identified by Lin−TCR/CD3ϵ− Thy1+CD127+RORγt+.DiscussionThe ILC population is heterogeneous and the strategies to identify ILCs have to be designed fo

Cancers | Free Full-Text | Detection and Molecular Characterization of Circulating Tumour Cells: Challenges for the Clinical Setting | from Flow Cytometry to Cytomics | Scoop.it
Over the last decade, liquid biopsy has gained much attention as a powerful tool in personalized medicine since it enables monitoring cancer evolution and follow-up of cancer patients in real time. Through minimally invasive procedures, liquid biopsy provides important information through the analysis of circulating tumour cells (CTCs) and circulating tumour-derived material, such as circulating tumour DNA (ctDNA), circulating miRNAs (cfmiRNAs) and extracellular vehicles (EVs). CTC analysis has already had an important impact on the prognosis, detection of minimal residual disease (MRD), treatment selection and monitoring of cancer patients. Numerous clinical trials nowadays include a liquid biopsy arm. CTC analysis is now an exponentially expanding field in almost all types of solid cancers. Functional studies, mainly based on CTC-derived cell-lines and CTC-derived explants (CDx), provide important insights into the metastatic process. The purpose of this review is to summarize the latest findings on the clinical significance of CTCs for the management of cancer patients, covering the last four years. This review focuses on providing a comprehensive overview of CTC analysis in breast, prostate and non-small-cell lung cancer. The unique potential of CTC single-cell analysis for understanding metastasis biology, and the importance of quality control and standardization of methodologies used in this field, is also discussed.

Ultra-sensitive CTC-based liquid biopsy for pancreatic cancer enabled by large blood volume analysis | Molecular Cancer | Full Text

Ultra-sensitive CTC-based liquid biopsy for pancreatic cancer enabled by large blood volume analysis | Molecular Cancer | Full Text | from Flow Cytometry to Cytomics | Scoop.it
The limited sensitivity of circulating tumor cell (CTC) detection in pancreatic adenocarcinoma (PDAC) stems from their extremely low concentration in the whole circulating blood, necessitating enhanced detection methodologies. This study sought to amplify assay-sensitivity by employing diagnostic leukapheresis (DLA) to screen large blood volumes. Sixty patients were subjected to DLA, with a median processed blood volume of ~ 2.8 L and approximately 5% of the resulting DLA-product analyzed using CellSearch (CS). Notably, DLA significantly increased CS-CTC detection to 44% in M0-patients and 74% in M1-patients, yielding a 60-fold increase in CS-CTC enumeration. DLA also provided sufficient CS-CTCs for genomic profiling, thereby delivering additional genomic information compared to tissue biopsy samples. DLA CS-CTCs exhibited a pronounced negative prognostic impact on overall survival (OS), evidenced by a reduction in OS from 28.6 to 8.5 months (univariate: p = 0.002; multivariable: p = 0.043). Additionally, a marked enhancement in sensitivity was achieved (by around 3-4-times) compared to peripheral blood (PB) samples, with positive predictive values for OS being preserved at around 90%. Prognostic relevance of CS-CTCs in PDAC was further validated in PB-samples from 228 PDAC patients, consolidating the established association between CTC-presence and reduced OS (8.5 vs. 19.0 months, p < 0.001). In conclusion, DLA-derived CS-CTCs may serve as a viable tool for identifying high-risk PDAC-patients and aiding the optimization of multimodal treatment strategies. Moreover, DLA enables comprehensive diagnostic profiling by providing ample CTC material, reinforcing its utility as a reliable liquid-biopsy approach. This high-volume liquid-biopsy strategy presents a potential pathway for enhancing clinical management in this malignancy.

Cancers | Free Full-Text | Circulating Tumor Cell Detection Technologies and Clinical Utility: Challenges and Opportunities

Cancers | Free Full-Text | Circulating Tumor Cell Detection Technologies and Clinical Utility: Challenges and Opportunities | from Flow Cytometry to Cytomics | Scoop.it
The potential clinical utility of circulating tumor cells (CTCs) in the diagnosis and management of cancer has drawn a lot of attention in the past 10 years. CTCs disseminate from tumors into the bloodstream and are believed to carry vital information about tumor onset, progression, and metastasis. In addition, CTCs reflect different biological aspects of the primary tumor they originate from, mainly in their genetic and protein expression. Moreover, emerging evidence indicates that CTC liquid biopsies can be extended beyond prognostication to pharmacodynamic and predictive biomarkers in cancer patient management. A key challenge in harnessing the clinical potential and utility of CTCs is enumerating and isolating these rare heterogeneous cells from a blood sample while allowing downstream CTC analysis. That being said, there have been serious doubts regarding the potential value of CTCs as clinical biomarkers for cancer due to the low number of promising outcomes in the published results. This review aims to present an overview of the current preclinical CTC detection technologies and the advantages and limitations of each sensing platform, while surveying and analyzing the published evidence of the clinical utility of CTCs.
