Abstract

Embryonic stem cells are derived from inner cell mass of an embryo that can differentiate into every cell type in the body. Clinically, cultured red blood cell supply is of great interest. However, some of the hurdles need to be overcome. This protocol describes a protocol to maintain mouse stem cells that will be used for hematopoietic lineage differentiation assay in the lab.
