myo- + -blast (Wiktionary)

Examples

  • Put simply, the process relies on a muscle precursor cell known as a myoblast, a sort of stem cell preprogrammed to grow into muscle.

  • In this study, we show that Pitx2 is phosphorylated by the protein kinase Akt2 and is necessary to ensure proper C2C12 myoblast proliferation and differentiation.

  • We propose that unphosphorylated Pitx2 is required to favor HuR-mediated Ccnd1 mRNA stabilization, thus sustaining myoblast proliferation.
