中文摘要：

生长因子是细胞合成和分泌的一类活性蛋白质,在促进组织再生、修复及创伤愈合等方面发挥重要作用。生理性的组织修复与再生过程是在多种生长因子共同调节下完成的,因此模拟生理性组织修复过程,可控性释放多种生长因子在组织工程领域具有广阔的应用前景。

英文摘要：

Growth factors are a group of activated proteins synthesized and excreted from cells, which play a critical role in wound healing, tissue repair and tissue regeneration. Natural tissue repair and regeneration processes are regulated by multiple growth factors, thus mimic the natural healing processes, controlled release multiple growth factors is a promising application in tissue engineering.
