biology using ultra-high throughput data Jihwan Park Gwangju Institute of Science and Technology The
recent advances in ultra-high-throughput single-cell sequencing technologies
have fueled an exponential growth of single-cell sequencing data available in
the public, which currently harbors hundreds of millions of cells in total.
Using the public data, we performed pan-cancer analysis on 226 samples from 164
donors across 10 types of solid cancers to profile tumor microenvironment (TME)
at single-cell resolution. The activation trajectory of fibroblasts into
various major types of cancer-associated fibroblasts was divided into three
distinct differentiated states, and was capable of sculpting TME, which was
associated with prognosis of immunotherapy. However, currently available
bioinformatic tools for single cell analysis, including SCANPY, Seurat, and
Monocle, are largely inappropriate for the integrative analysis of large single
cell data containing millions of cells due to the extensive memory footprint
required by such analysis. Here, we developed SC-Elephant, an extremely
memory-efficient single cell analysis platform that enables routine analysis of
millions of cells using a typical desktop or billions of cells in a server. |
