Single-Cell Transcriptomic Analysis of Hematopoietic Cells.

Single-cell RNA sequencing (scRNA-Seq) allows the complete and unbiased analysis of the transcriptional state of an individual cell. In the past 5 years, scRNA-Seq contributed to the progress of the hematology field, advancing our knowledge of both normal and malignant hematopoiesis. Different scRNA-Seq methods are available, all relying on the conversion of RNA to cDNA, followed by amplification of cDNA in order to obtain a sufficient amount of genetic material for sequencing. Currently available scRNA-Seq platforms can be broadly divided into two categories: droplet-based and plate-based. Each of these approaches has advantages and disadvantages that need to be considered when designing the experiment. Here, we describe detailed protocols of two of the most used methods for scRNA-Seq of hematopoietic cells: Smart-Seq2 (plate-based) and 10× Genomics (droplet-based).
