Glycitin, a natural isoflavone, could promote the proliferation of bone marrow stromal cells and osteoblasts and protect the loss of bone. It can be isolated and purified from legumes. Administration of glycitin increased cell proliferation and promoted osteoblast formation from BMSCs. Furthermore, glycitin activated the gene expression of Col I and ALP in BMSCs. Notably, glycitin suppressed protein expression of TGF-β and AKT in BMSCs[3]. Co-treatment with TMF and glycitin synergistically promotes the proliferation and migration of both keratinocytes and dermal fibroblasts, with a 1:1 ratio of these compounds showing the greatest efficacy in our co-culture system[4]. Glycitin significantly prevents bone loss in variectomized (ovx) rats at a dose of 50 mg/kg/d. At this dose glycitin also prevents ovx-induced uterine atrophy and increases in body weight gain, abdominal fat, serum total cholesterol and triglyceride, and urinary excretion of pyridinoline and deoxypyridinoline with statistical significance[5].
