Tumors exhibit genetic and phenotypic diversity leading to intra-tumor
heterogeneity (ITH). Further complex ecosystem (stromal and immune cells) of
tumors contributes into the ITH. This ITH allows tumors to overcome various
selection pressures such as anti-cancer therapies and metastasis at distant
organs. Single-cell RNA-seq (scRNA-seq) has provided unprecedented insights into
ITH and its implications in drug resistance and metastasis. As scRNA-seq
technology grows and provides many new findings, new tools on different
programming platforms are frequently generated. Here, we aim to provide a
framework and guidelines for new entrants into the field of scRNA-seq. In this
review, we discuss the current state-of-art of scRNA-seq analysis step-by-step
including filtering, normalization and analysis. First, we discuss the brief
history of experimental methods, followed by data processing and implications in
precision oncology.
