The perivascular niche of endometrial mesenchymal stromal/stem-like cells

Human endometrium is a unique adult tissue that undergoes cyclical shedding, repair, and regeneration during a woman’s reproductive life. Over the past 2 decades, tremendous progress has been made towards the identification and characterization of endometrial stromal stem/progenitor cells . The substantial regeneration of vascularized stroma in the endometrium during the proliferative stages of each menstrual cycle is likely to be mediated by endometrial mesenchymal stromal/stem cells. This review focuses on the perivascular niche for CD140b+CD146+ pericytes and SUSD2+ perivascular cells. The identity, characteristics, and underlying mechanisms of uterine regeneration are also discussed.
