Abstract

Articular cartilage defects are common, causing significant morbidities. Tissue engineering using pluripotent stem cells is a new promising modality for cartilage repair. In the current study, we investigated the chondrogenesis of rabbit adipose-derived stem cells (ADSCs). We isolated rabbit ADSCs and transfected these cells with constructs encoding human insulin growth like factor 1 (IGF-1) and bone morphogenic protein 2 (BMP-2). We examined the growth and morphology of these transfected cells and their production of type II collagen and MMP-3. We found that IGF-1 and BMP-2 drove the chondrogenesis of ADSCs, which showed mature chondrocyte-like cells and formed cartilage nodules. These cells also produced type II collagen with a reduced production of MMP-3. Our findings suggested that human ADSCs could differentiate into chondrocyte-like cells driven by IGF-1 and BMP-2 and held promises as an abundant and ready source of stem cells for cartilage repair and regeneration.
