Recently， cartilage tissue engineering has become a cornerstone to treat cartilage degeneration and osteoarthritis (OA)。 Fibronectin1 (FN1) is described as multiple functional glycoproteins that play an essential role in chon-drogenic and osteogenic differentiation。 Few studies reported the potential of FN1 to enhance tissue engineering and reduce the death of chondrocytes in OA。 Further， FN1 possesses multiple binding domains including collagen， integrin， and heparin that can interact with heparan sulfate proteoglycans at the surface of chondrocyte leading to promote cell signaling and differentiation。 Recent studies suggested that FN1 can promote chondrocyte differentiation by upregulating TGF-β/PI3K/Akt pathways。 Further， FN1 can inhibit the apoptosis of chondrocytes by preventing the release of metalloproteinases through lowering the expression of p-PI3K/PI3K and p-AKT/AKT pathways。 However， the use of FN1 in cartilage repair studies using animal models or clinical trials was rarely reported。 Therefore， this article provides new insights into the importance of FN1 in cartilage tissue engineering to encourage more studies concerning FN1 in cartilage repair studies。 Further， we provided new suggestions for advanced applications of FN1 to treat OA and cartilage degeneration。
