Comparison of mesenchymal stromal cells of embryonic and adult rat spleen showed that splenic cells from 20-day rat fetuses exhibit the capacity for clonal growth, express surface antigens CD73, CD90, and CD106, and have weak osteogenic and adipogenic potencies, while splenic cells from adult animals are characterized by lower cloning efficiency, rapid decrease of proliferative activity during passaging, the absence of CD73 and CD90 expression, and are incapable of osteogenesis The observed changes are probably related to extinction of myelopoiesis in the spleen during the postnatal ontogeny.

    In order to verify whether differentiation of adult stem cells toward bone tissue is promoted by high-frequency vibration (HFV), bone marrow stromal cells (BMSCs) were mechanically stimulated with HFV (30 Hz) for 45 minutes a day for 21 or 40 days. Cells were seeded in osteogenic medium, which...

    Abstract. The regressive biological function of human bone marrow-derived mesenchymal stem cells (hBMSCs) is one of the key factors resulting in the decrease of bone mass in senile osteoporosis. MicroRNAs (miRs) are non-coding small RNAs involved in various gene regulation processes. Whether any...

    Background: Adenomatous polyposis coli (Apc) is a tumor suppressor that inhibits Wnt/Ctnnb1. Mutations of Apc will not only lead to familial adenomatous polyposis with associated epithelial lesions, but will also cause aggressive fibromatosis in mesenchymal cells. However, the roles of Apc in...
