<abstract xmlns="http://www.w3.org/1999/xhtml"> Background: Human endometrial-derived stem cells (hEnSCs) as multipotent accessible source of cells are known as useful cell candidates in the field of bone tissue engineering.

After tissue digestion in collagenase, the isolated endometrial cells were expanded in Dulbecco’s modified Eagle medium (DMEM) supplemented with 10% FBS. The propagated cells were characterized based on the expression of endometrial (CD90, CD105), endothelial (CD31), and hematopoietic (CD34, CD133) stem cell markers. Cells were differentiated in osteogenic medium containing DMEM supplemented with 10% FBS, 10 nM dexamethasone, 50 μg/ml Ascorbic acid, and 10 mM β-glycerophosphate in the presence or absence of BMP-2 for 21 days. Alizarin red staining was performed to verify the matrix mineralization. Immunocytochemical staining was conducted to detect the expression of OCT-4, CD133, and osteopontin as well as osteocalcin. The expression of osteoblast transcripts, including osteopontin, osteonectin, and alkaline phosphatase (ALP) were analyzed by semi quantitative PCR.Results: The expanded EnSCs were spindle shaped. They were positive for the expression of Oct-4, CD90, and CD105, while they were negative for endothelial and hematopoietic markers. The matrix mineralization was confirmed by Alizarin red in both groups at day 21. Although the expression of osteopontin and osteocalcin was detected in both groups by immunological staining, the expression of osteocalcin was more intense in the presence of BMP-2. ALP, Osteonectin and osteopontin transcripts were expressed in all groups; however, the expression of ALP and osteopontin was upregulated in the presence of BMP-2.Conclusion: BMP-2 as an osteoinductive growth factor, could promote the osteogenic differentiation of EnSCs in vitro.</abstract>
