Fig. 19From: Endogenous, tissue-resident stem/progenitor cells in gonads and bone marrow express FSHR and respond to FSH via FSHR-3FSH exerts direct effect on the endometrial epithelial cells and the stem cells. FSHR treatment for 5 days exerted a marked effect on the endometrial epithelial cells which showed both hyperplasia and hypertrophy. Note the presence of small spherical cells which are the VSELs cut in different plains of sections. They also appeared to be dividing at few places (broken circles) [68].
