Endometrial stromal cell (eSC (also EnSC))

Endometrial stromal cells (eSCs) are multipotent mesenchymal stromal cells derived from the endometrium that constitute the largest cellular compartment of the uterine lining.[1][3] These cells exhibit remarkable regenerative capacity and are intrinsically involved in the cyclical remodeling of the endometrium, which undergoes approximately 450 cycles of regeneration during a woman's reproductive lifetime.[1][4] eSCs exhibit a mesenchymal stromal cell phenotype with the capacity for self-renewal and differentiation, and they play critical roles in endometrial tissue homeostasis, embryo implantation, decidualization during pregnancy, and immune tolerance.[1][3][6] Upon hormonal stimulation (progesterone and estrogen), eSCs undergo decidualization, transitioning into a highly secretory phenotype that produces extensive extracellular matrix proteins, cytokines, and growth factors essential for pregnancy maintenance.[6] These cells demonstrate potent immunomodulatory properties, including suppression of T cell proliferation and secretion of anti-inflammatory factors, which support tissue repair and maternal immune tolerance during pregnancy.[1] eSCs are currently being investigated as a cell therapy candidate for various endometrial disorders associated with reproductive failure, including Asherman's syndrome, recurrent implantation failure, and thin endometrium, rather than as a molecular drug target.[1][3]

Not applicable - endometrial stromal cells are not a molecular drug target. However, their therapeutic mechanism as cell therapy involves: - Immunomodulatory secretion of anti-inflammatory factors[1] - Secretion of trophic and regenerative factors[9] - Suppression of CD4+ T cell proliferation and activation[1] - Differentiation of effector memory T cells[1]
