New Stem Cells Study Results Reported from
Our news journalists obtained a quote from the research, "Cell cycle and cell apoptosis were analyzed with flow cytometry to measure the viability of hDPSCs. Reverse transcription-polymerase chain reaction (RT-PCR) and western blotting were used to evaluate the expression levels of osteogenic marker genes and proteins of hDPSCs. Alkaline phosphatase (ALP) staining and alizarin red S assay were used to evaluate the ALP activity of hDPSCs and their calcium deposition potential. In addition, hDPSCs and scaffolds were implanted subcutaneously in nude mice for 8 weeks. Harvested tissues were immunohistochemically stained for osteocalcin (OCN) expression from hDPSCs, and stained with alizarin red S for examination of their calcium deposition in vivo. The ISCS had no adverse effect on hDPSCs, promoted their proliferation, and significantly up-regulated the expression of osteogenesis-related genes and proteins. The hDPSCs co-cultured with ISCS in ODM exhibited the highest ALP activity and calcium deposition in vitro. The ISCS promoted the OCN expression and calcium deposition of hDPSCs after ectopic transplantation in vivo. Intrafibrillar-silicified collagen scaffolds significantly promoted the proliferation, osteogenic differentiation and mineralization of hDPSCs, when compared with NCS."
According to the news editors, the research concluded: "This study demonstrates combining the use of hDPSCs and ISCS to promote bone-like tissue formation is a promising approach for clinical bone repair and regeneration."
