Popis: Cartilage tissue is avascular with less regeneration potential and therefore, cartilage regeneration is still a major challenge for therapeutic approaches. Commonly used treatment strategies involve the transplantation of autologous chondrocytes into the defect. Before that, it is required to increase the cell number in vitro resulting in unwanted chondrocyte dedifferentiation. This could impair subsequent tissue regeneration. Both growth factors TGF-ß1 and IGF-1 are used as strong inducer of chondrogenic redifferentiation, however, a controlled application of TGF-ß1 is essential to avoid adverse effects. Therefore, in the present study, we investigated the time-dependent influence of TGF-ß1 administration on chondrocyte redifferentiation.
