Spermatogonia and sperm-like cells can be derived in vitro via the addition of RA (retinoic acid) to pluripotent ES and EG cells. At present, however, these cells have not been derived from unipotent cells. Here, we have generated premeiotic Stra8-positive cells from C2C12 myoblasts following treatment with 10 μM all-trans-RA for 8 days. The differentiated C2C12 cells exhibited spherical morphology similar to spermatogonia, and they expressed gene markers of premeiosis, meiosis and postmeiosis. In addition, some of the transdifferentiated Stra8-positive cells had a tail-like phenotype. Flow cytometry results indicated that up to 20% of RA-induced C2C12 cells were Stra8-positive. Mvh (mouse vasa homologue) protein, a germ cell-specific ATP-dependent RNA helicase and Prm1 (protamine 1) were detected in transdifferentiated cells. The DNA content in induced C2C12 cells showed that Stra8-positive cells were diploid, suggesting that the myoblast transdifferentiation was in the premeiotic stage of spermatogenesis. The derivation of Stra8-positive cells from C2C12 myoblasts has important implications for studying unipotent cell differentiation. Furthermore, C2C12 myoblasts may provide a useful in vitro cell model to study signal transduction and transdifferentiation during RA treatments. |
