Abstract:

BACKGROUND: Estrogen is closely related to normal bone metabolism in human body and provides favorable conditions for osteogenic differentiation of stem cells.
OBJECTIVE: To summarize the application, mechanism of action, safety, efficacy, advantages/disadvantages, and characteristics of estrogen in inducing osteogenic differentiation of various stem cells.
METHODS: A computer-based online retrieval of PubMed, CNKI and Wanfang databases was performed for searching papers using the key words “estrogen, bone marrow mesenchymal stem cells, adipose-derived stem cells, embryonic stem cells, osteogenesis” in English and Chinese.
RESULTS AND CONCLUSION: Fifty papers were suitable for final analysis. Estrogen is the most important endocrine hormone. It is a safe and effective inducing agent used in the osteogenic differentiation of stem cells, promotes the proliferation and differentiation of stem cells and exerts different actions on stem cells. Estrogen directly influences on the estrogen receptor of the stem cells and also directly influences cell proliferation and differentiation by inducing the production of various cytokines. Nevertheless, there are some uncertainties, including estrogen level, estrogen-target gene expression and transcription on stem cells, and cell-scaffold reconstruction, which should be further studied.
