Abstract
CD34 is a glycosylated cell surface protein and represents a well-known marker for primitive progenitor cells in various organs, especially cord blood, bone marrow and fetal liver. CD34+ progenitor cells are suitable for a series of studies, e.g. cell differentiation, transplantation as well as construction of humanized mouse models. Here, we describe a method to isolate CD34+ cells from the human cord blood and fetal liver.
Cord Blood (脐带血)
Fetal liver (胎肝)
Magnetic purification (磁净化)
Hepatic progenitor cells (肝前体细胞)
