Bovine endometrial stromal cells display osteogenic properties
نویسندگان
چکیده
The endometrium is central to mammalian fertility. The endometrial stromal cells are very dynamic, growing and differentiating throughout the estrous cycle and pregnancy. In humans, stromal cells appear to have progenitor or stem cell capabilities and the cells can even differentiate into bone. It is not clear whether bovine endometrial stromal cells exhibit a similar phenotypic plasticity. So, the present study tested the hypothesis that bovine endometrial stromal cells could be differentiated along an osteogenic lineage. Pure populations of bovine stromal cells were isolated from the endometrium. The endometrial stromal cell phenotype was confirmed by morphology, prostaglandin secretion, and susceptibility to viral infection. However, cultivation of the cells in standard endometrial cell culture medium lead to a mesenchymal phenotype similar to that of bovine bone marrow cells. Furthermore, the endometrial stromal cells developed signs of osteogenesis, such as alizarin positive nodules. When the stromal cells were cultured in a specific osteogenic medium the cells rapidly developed the characteristics of mineralized bone. In conclusion, the present study has identified that stromal cells from the bovine endometrium show a capability for phenotype plasticity similar to mesenchymal progenitor cells. These observations pave the way for further investigation of the mechanisms of stroma cell differentiation in the bovine reproductive tract.

P-99: Survey of Noscapine Effect on Apoptosis of Human Endometrial Stromal Cells: An In Vitro Study
Background: Noscapine is a water soluble alkaloid with antitussive property and very less toxicity. It is obtained from the Papaveraceae family. Recently, new pharmacological properties such as anticancer, anti stroke and anti-angiogenic effects are introduced. There is no scientific report on noscapine effect on reproductive system. The aim of present study was to determine in vitro effect of ...
متن کاملHeparin-binding proteins from boar seminal plasma affecting the release of prostaglandins and interleukin-6 by porcine endometrial and cervical cells and bovine endometrial cells
The objectives of this study were to explore whether heparin-binding proteins, separated by fast protein liquid chromatography from boar seminal plasma influence the release of prostaglandins F2α, (PGF2α), E2 (PGE2) and interleukin-6 (IL-6) by porcine endometrial and cervical cells and even bovine endometrial cells. In Experiment I, we showed that release of PGF2α by endometrial epithelial, end...
متن کاملOsteogenic actions of the osteogenic growth peptide on bovine marrow mesenchymal stromal cells in culture
S: The osteogenic growth peptide (OGP) regulates the differentiation of marrow mesenchymal stem cells derived from human and rodent cell lines into osteoblasts. Whether OGP directly regulates the bovine marrow mesenchymal stem cells differentiating into osteoblasts remains unknown. In this study, we evaluated the effects of OGP on the growth and differentiation of bovine marrow mesenchymal stem...

Background Endometriosis is the presence of endometrial tissue outside of the uterine cavity and is the most common gynecologic disorder in women of reproductive age. We have preliminary evidence that in the presence of a 3-dimensional (3-D) fibrin matrix, human endometrial glands, stroma, and neovascularization can develop in vitro, mimicking the earliest stages of endometriosis. The aim of th...
