Characterization of highly proliferative decidual precursor cells during the window of implantation in human endometrium.

Stem Cells 2021 Mar 25. Epub 2021 Mar 25.

Division of Biomedical Sciences, Warwick Medical School, University of Warwick, Coventry, UK.

Pregnancy depends on the wholesale transformation of the endometrium, a process driven by differentiation of endometrial stromal cells (EnSC) into specialist decidual cells. Upon embryo implantation, decidual cells impart the tissue plasticity needed to accommodate a rapidly growing conceptus and invading placenta, although the underlying mechanisms are unclear. Here we characterize a discrete population of highly proliferative mesenchymal cells (hPMC) in midluteal human endometrium, coinciding with the window of embryo implantation. Read More

Uterine Stem Cells and Benign Gynecological Disorders: Role in Pathobiology and Therapeutic Implications.

Stem Cell Rev Rep 2020 Nov 5. Epub 2020 Nov 5.

Department of Gynecology & Obstetrics, Johns Hopkins University School of Medicine, 720 Rutland Avenue, Baltimore, MD, 21205, USA.

Stem cells in the endometrium and myometrium possess an immense regenerative potential which is necessary to maintain the menstrual cycle and support pregnancy. These cells, as well as bone marrow stem cells, have also been implicated in the development of common benign gynecological disorders including leiomyomas, endometriosis and adenomyosis. Current evidence suggests the conversion of uterine stem cells to tumor initiating stem cells in leiomyomas, endometriosis stem cells, and adenomyosis stem cells, acquiring genetic and epigenetic alterations for the progression of each benign condition.
