摘要
心肌组织通过物理、化学或其他方法进行脱细胞处理后,制备成的脱细胞基质含有许多细胞外基质成分,包括蛋白质、胶原、多糖以及生长因子等,不仅对细胞生长有很好的生物相容性,而且还能有助于细胞的修复和再生,是一种很有前途的心血管修复材料。脱细胞基质水凝胶是将脱细胞基质进行凝胶化后,所形成的一种具有生物相容性、可降解性以及可注射性的生物材料,不仅保留了脱细胞基质本身的优点,而且增加了可注射性这一优势,可在心肌梗死后进行微创注射,从而对心脏产生修复作用。
After decellularization of myocardial tissue by physical,chemical or other methods,the prepared decellularized extracellular matrix(dECM) contains many extracellular matrix components,including proteins,collagen,polysaccharides and growth factors.It not only has good biocompatibility for cell growth,but also contributes to cell repair and regeneration,which is a promising material for cardiovascular repair.dECM hydrogel is a biocompatible,degradable and injectable biological material formed after gelling the dECM,which not only retains the advantages of the dECM itself but also increases the advantage of injectability,and can be minimally invasive injection after myocardial infarction,thereby having a repair effect on the heart.
