Stem cells can self-renew according to the type of stimulus or signal they receive, differentiate into different cell phenotypes and repair damaged tissue. Depending on the breadth of the type of differentiation, stem cells can be divided into totipotent, pluripotent, multipo tent, and unipotent. Totipotent stem cells (such as fertilized eggs and morula blast cells) have the greatest differentiation potential and can differentiate into ectoderm, mesoderm and endoderm cells. Pluripotent stem cells can differentiate into cells of all three germ layers except for extraembryonic tissues, and ESCs derived from the inner cell mass of blastocysts are the most widely studied and deepest pluripotent stem cells. Specific stem cells, such as hematopoietic stem cells (haeIIlatopoieticstemcells, HScs) and mesenchymal stem cells (mesenchyIllalstemceUs, MSCs), also have the ability to self-renew and differentiate into a variety of specific cell types.
