1 results about "Decellularized scaffold" patented technology

This invention relates to the field of biomedical materials technology, providing a heparinized dual-growth factor recellularized adipose tissue decellularized scaffold material, its preparation method, and its applications. The preparation method includes: decellularizing adipose tissue to obtain adipose tissue decellularized scaffold; heparinizing the scaffold to obtain a heparinized adipose tissue decellularized scaffold; loading hepatocyte growth factor and vascular endothelial cell growth factor onto the scaffold to obtain a heparinized dual-growth factor adipose tissue decellularized scaffold; seeding induced pluripotent stem cell-derived hepatocytes onto the scaffold, and culturing to obtain a heparinized dual-growth factor recellularized adipose tissue decellularized scaffold (RAT). This invention uses rat inguinal adipose tissue to prepare RAT material, which is low-cost, readily available, has a simple preparation process, and is easy to scale up. The RAT material of this invention can achieve liver tissue damage repair and hepatocyte regeneration, providing a new treatment strategy for acute liver failure.
