● 根据肿瘤的生长速度,观察时间为2-10周。当使用VitroGel和AB-ECM两种细胞外基质时,六种实体瘤衍生的细胞系均能形成实体瘤,肿瘤类型和形态相似。
● 所有六种细胞类型应用两种细胞外基质,达到预定肿瘤体积大小所需的时间相同。
● 在大多数情况下,使用VitroGel系统移植的肿瘤显示出较小的标准偏差,意味着VitroGel系统得到的实验结果可重复,批次间一致。
● 以上结果说明水凝胶VitroGel系统可以作为AB-ECM的无异源替代品的效率,是一款具有前景的替代品。

结论
VitroGel系统不仅可以作为AB-ECM的替代品,还可以为科研人员控制系统组分提供便捷,控制这种水凝胶系统关键的生物物理或生物特性,比如机械强度、功能配体和微环境的可降解度等。因此,选择VitroGel系统开展体内研究也是一种创新的选择。
