目前存在很多由于先天缺陷、创伤或肿瘤切除等导致人体完整性缺陷的现象,故近年来组织工程成为研究热点。支架材料是组织工程的要素之一。人脂肪组织细胞外基质粉末呈三维空间结构,能促进干细胞增殖、分化、新生血管形成及生长因子释放等,已成为组织工程支架的新材料。 Currently there are many defects due to birth defects, trauma or tumor resection that lead to the integrity of the human body, so tissue engineering has become a research hot spot in recent years. Scaffold material is one of the elements of tissue engineering. Human adipose tissue extracellular matrix powder has a three-dimensional spatial structure, can promote stem cell proliferation, differentiation, angiogenesis and release of growth factors, has become a new material for tissue engineering scaffolds.
