  • A MORPHOLOGICAL STUDY OF CHONDROGENESIS BY ADIPOSE-DERIVED ADULT STEM CELLS INDUCED BY RECOMBINANT HUMAN BONE MORPHOGENETICPROTEIN 2

    Objective To investigate the possibility of differentiation of theisolated and cultured adipose-derived adult stem cells into chondrocytes, which is induced by the recombinant human bone morphogenetic protein 2 (rhBMP-2). Methods The rabbit adipose tissue was minced and digested by collagenase Type Ⅰ. The adposederived adult stem cells were obtained and then they were cultured inthe micropellet condition respectively in the rhBMP-2 group, the rhTGF-β1 group, the combination group, and the control group for 14 days. The differentiation of the adiposederived stem cells into chondrocytes was identifiedby the histological methods including HE, Alcian blue, Von kossa, and immunohistochemical stainings. Results After the continuous induction by rhBMP-2 and continuous culture for 14 days, the HE staining revealed a formation of the cartilage lacuna; Alcian blue indicated that proteoglycan existed in the extracellular matrix; the immunohistochemical staining indicated that collagen Ⅱ was in the cellular matrix; and Von kossa indicated that the adipose-derived stem cells couldnot differentiate into the osteoblasts by an induction of rhBMP-2. Conclusion In the micropellet condition, the adipose-derived adult stemcells can differentiate into the chondrocytes, which is initially induced by rhBMP-2. This differentiation can provide a foundation for the repair of the cartilage injury.
