| Abstract: | Protein synthesis in testicular germ cells was studied during the differentiation of Type A spermatogonia in testes from adult cryptorchid mice to Intermediate and Type B spermatogonia in organ culture by two-dimensional gel electrophoresis. By comparing the patterns of Type A spermatogonia with those of differentiated (Intermediate and Type B) spermatogonia, we found two newly synthesized protein spots that correlated with differentiation. The isoelectric points (pIs) and molecular weights (MWs) of these proteins were estimated to be approximately pI 5.4, MW 67,000, and pI 5.8, MW 28,000, respectively. |
