Description

一种水凝胶状的细胞培养配方
技术领域
本发明涉及细胞培养技术领域,特别涉及一种水凝胶状的细胞培养配方。
背景技术

进一步,由以下原料组成:以DMEM培养液55mL为基础,还含有棉籽糖3mL、葡萄糖3mL、胰岛素0.07mL、转铁蛋白0.008mL、生长激素0.0015mL、谷胱甘肽1.2mL、谷氨酰胺0.02mL、非必需氨基酸0.006mL、水凝胶7mL。
进一步,所述的非必需氨基酸由谷氨酸、丙氨酸、甘氨酸、天门冬氨酸、胱氨酸、脯氨酸、丝 氨酸和酪氨酸组成。
进一步,所述的水凝胶由热交联明胶制成。
进一步,所述水凝胶的含水率为75%以上且95%以下。
进一步,所述水凝胶的厚度为1μm以上且30mm以下。
本发明的有益效果是:通过对各种生长因子种类和多种组分和用量进行研究而获得,以无血清方式实现了胎盘间充质干细胞体外培养;在此无血清培养基体系中,间充质干细胞能够实现贴壁生长并有效地提高间充质干细胞的扩增能力,使得不含外源血清的培养体系更有利于干细胞被安全地应用于临床移植;水凝胶作为各种生长因子种类和多种组分的载体,细胞生长因子由水凝胶被缓释,持续为细胞培养提供各种生长因子种类和多种组分,保障细胞持续扩增能力。
