Core Tip
Core Tip: Adipose stem cells are important seed cells that are used in cartilage tissue engineering. However, at present, cartilage matrix secretion by adipose-derived stem cells (ADSCs) inevitably decreases during the late stage of induced chondrogenic differentiation in vitro, which seriously limits the further application of ADSCs. Our team found that the level of inflammation in the culture system, mainly the levels of tumor necrosis factor-alpha (TNF-α) and matrix metalloproteinase 3, continuously increased during the chondrogenic differentiation of ADSCs. To address this issue, our team added etanercept or infliximab, which are targeted inhibitors of TNF-α, to the chondrogenic differentiation induction medium and successfully restored matrix formation by human ADSCs in the late stage of chondrogenic differentiation. Further studies found that these effects were achieved by reducing NF-κB pathway activation.
