Abstract (original English)

The growth plate is a cartilage tissue located between the epiphysis and diaphysis of long bones, responsible for the longitudinal growth of the skeleton. Due to its limited regenerative capacity, when the growth plate is damaged, it is typically replaced by inappropriate bone tissue, leading to the formation of bony bridges. These bony bridges not only restrict normal skeletal growth but may also cause limb length discrepancies, angular deformities, and functional impairments. Although traditional clinical treatments have shown some effectiveness, they are often associated with severe complications and poor prognoses. Therefore, the development of effective therapeutic strategies to prevent the formation of bony bridges and promote the repair and regeneration of the growth plate has become a current research focus. Cartilage tissue engineering, as an emerging therapeutic approach, restore the function of the growth plate through the substitution or repair of damaged cartilage tissue, has been widely applied in the repair of growth plate injuries. Cartilage tissue engineering for growth plate injury primarily relies on three key components: seed cells, growth factors, and scaffold materials. Seed cells provide the basis for cartilage regeneration, typically using autologous or allogeneic chondrocytes, mesenchymal stem cells, etc.,; growth factors such as bone morphogenetic prot
