外源性生长因子在泌尿系统组织工程研究中具有重要作用,但由于生长因子半衰期短,越来越多的研究利用各种控制释放载体,使生长因子在体内以恒定的速率缓慢而持续地释放,以保证其在支架材料中的含量,从而促进组织再生。本文就生长因子在泌尿系统组织工程中的控制释放策略的最新进展进行综述。 Exogenous growth factors play an important role in the research of urological tissue engineering. However, due to the short half-life of growth factors, more and more researches use various controlled release carriers to slowly and consistently release growth factors in the body at a constant rate , In order to ensure its content in the scaffold material, thereby promoting tissue regeneration. This article reviews the recent advances in the strategy of controlled release of growth factors in urological tissue engineering.
