Fig. 9From: Endogenous, tissue-resident stem/progenitor cells in gonads and bone marrow express FSHR and respond to FSH via FSHR-3Mice treated with PMSG (10 IU) showed increased numbers of germ cells in H&E-stained sections. This was confirmed by increased PCNA and OCT-4 expression. PCNA expression was studied after 24 and 72 h and increased numbers of germ cells was clearly evident [52]. Scale: 20 μmBack to article page
