Objective:
To investigate the possibility of directional differentiation of human adipose stem cells (hADSCs) into endothelial cells (EC), so as to provide seed cells for tissue engineered vessels.
Methods:
hADSCs were isolated from human adipose tissue by collagenase digestion, cultured and amplified by adherence to flasks. Then hADSCs were directionally induced to differentiate into EC by a combination of fibronectin (FN), endothelial cells support liquid (EGM2-MV) containing various growth factors and high concentration of VEGF165 (50 ng/ml). Then, the cells morphology, phenotype and function were identified.
Results:
Highly homologous hADSCs were obtained, and then hADSCs were directionally differentiated into EC. CD31 and CD34, the specific markers for EC, and vascular endothelial growth factor receptor (KDR) were positive by immunohistochemical staining and RT-PCR. In addition, unique Weibel-Palade bodies in EC were observed under transmission electron microscope. Functionally, hADSCs could swallow Dil-Ac-LDL and form tube-like structures in matrigel after endothelial differentiation.
Conclusions:
hADSCs can be successfully induced to differentiate into endothelial cells in vitro.
