Abstract:
Objective To isolate and culture meshenchymal stem cells from murine fetal liver.Methods flMSCs from mouse fetuses were isolated by adhering to plastic surface.Growth kinetics was determined by growth curve.Cell cycle and phenotype were analyzed by FACSan flow cytometry.Differentiation of adhering cells was induced and identified.Results Homogenous fibroblast-like cells were predominated in culture.The counting of flMSCs increased 2 fold after 24 hours and 83.76%?2.88% of flMSCs were in G0/G1 phases.flMSCs were CD44,CD29 positive but negative for the markers of hematopoietic cells such as CD45,CD11b.flMSCs were able to differentiate along adipogenic,chondrogenic and osteogenic pathways even after being passaged several times.ConclusionflMSCs can be isolated by their plastic-attachable property and can expand without losing their multiple differentiation potential in vitro.flMSCs may offer an appropriate cell source for stem cell therapy.
