ABSTRACT
AIM:
To investigate the cytological basis and differentiating conditions of human bone marrow mesenchymal stem cells (hMSCs) differentiated into cells of the endothelial lineage in vitro.METHODS:
hMSCs were isolated by density gradient centrifugation and fractionated on a 1 073 g/L Percoll. The combination of VEGF165 and various matrix proteins including fibronectin (FN) and type I collagen (Col) was used to induce hMSCs in vitro. Cells were characterized by immunohistochemistry, cytochemistry, FACS and ultrastructure to identify and detect the differentiated population and markers.RESULTS:
hMSCs was positive for KDR. PAS reaction was positive and ultrastructure of hMSCs showed glycogen- pool in ectoplasm. Glycogen reducing or disappear suggested that stem cells have occurred differentiation. Induction of hMSCs resulted in the increase of KDR, β1 integrin and CD34.CONCLUSION:
hMSCs were induced to a transit population (TP( )) that differentiated toward the endothelial progenitor cells ( EPC), but not a really EPC. hMSCs pedigree diagram of differentiation was hMSCs→TP→EPC→endothelial cells (Ecs).
