Tumors are highly complex tissues composed of cancerous cells, surrounded by a heterogeneous cellular microenvironment. A tumor’s response to treatments is governed by an interaction of the cancer cell’s intrinsic factors with external influences of the tumor microenvironment. Disentangling the heterogeneity within a tumor is a crucial step in the development and utilization of effective cancer therapies. The single cell sequencing technology enables an effective molecular characterization of single cells within the tumor. This technology can help deconvolute heterogeneous tumor samples and thus revolutionize personalized medicine. However, a governing challenge in cancer single cell analysis is cell annotation, that is, the assignment of a particular cell type or a cell state to each sequenced cell. The identification of tumor cells within single cell or spatial sequencing experiments remains a critical and limiting step for research, clinical, and commercial applications. In this webinar, we will discuss these challenges and a novel machine learning pipeline aimed at performing automatic annotation and distinguishing tumor cells from normal cells at the single cell level.
About the speaker:
Altuna Akalin is a bioinformatics scientist and the head of Bioinformatics and Omics Data Science Platform at the Berlin Institute of Medical Systems Biology, Max Delbrück Center (MDC) in Berlin. He has developed computational methods for analysing and integrating large-scale genomics data sets since 2002. He uses machine learning and statistics to uncover biological patterns, for example those related to disease state and type. In his current work he uses complex molecular signatures to provide decision support systems for disease diagnostics and biomarker discovery. Additionally, he is actively involved in organising and teaching at computational genomics courses.
