Abstract:

Tissue engineering approaches for promoting the repair of cartilage lesions have focused on cell-based therapies involving mesenchymal stem cells(MSCs). Infrapatellar fat pad (IPFP) is an attractive cell resource of the adipose mesenchymal stem cells(ASCs), which can be collected and harvested by a convenient and minimally invasive procedure. The proliferation of IPFP-ASCs in vitro is fast and the ability to differentiate into cartilage is relatively strong. Hypoxia, TGF-β1, TGF-β3, BMP-7 have been proved to be able to enhance the chondrogenesis of infrapatellar fat pad derived adipose stem cells. In vivo studies indicate that application of IPFP-ASCs can effectively improve symptoms of cartilage injury and joint function. Although there are biological and technical difficulties to be overcome, the implantation of IPFP-ASCs are expected to become a good strategy to repair articular cartilage injury, including osteoarthritis.
