Zusammenfassung: | Embryonic stem cells (ESCs) are a renewable cell source of tissue for regenerative therapies. The addition of bone morphogenetic protein 4 (BMP4) to serum-free ESC cultures can induce primitive streak-like mesodermal cells. In differentiated mouse ESCs, platelet-derived growth factor receptor-α (PDGFR-α) and E-cadherin (ECD) are useful markers to distinguish between paraxial mesodermal progenitor cells and undifferentiated and endodermal cells, respectively. Here, we demonstrate methods for BMP4-mediated induction of paraxial mesodermal progenitors using PDGFR-α and ECD as markers for purification and characterization. Serum-free monolayers of ESCs cultured with BMP4 could efficiently promote paraxial mesodermal differentiation akin to embryonic mesodermal development. BMP4 treatment alone induced paraxial mesodermal progenitors that could differentiate into osteochondrogenic cells
in vitro and
in vivo. Furthermore, early removal of BMP4 followed by lithium chloride (LiCl) promoted the differentiation to myogenic progenitor cells. These myogenic progenitors were able to differentiate further
in vitro into mature skeletal muscle cells. Thus, we successfully induced the efficient bidirectional differentiation of mouse ESCs toward osteochondrogenic and myogenic cell types using chemically defined conditions. |
