以下协议提出了一种基于剪切的挤出方法,用于制造具有纳米级图案原纤维的胶原水凝胶,该方法可应用于广泛的组织工程应用。

我们小组的首要科学使命是使用生物工程策略开发创伤性肌肉骨骼损伤的治疗方法。具体来说,我们设计了具有可调生物物理特性的材料,以调节细胞外环境并驱动再生细胞表型。我们的目标是利用这些材料最终改善愈合并提高生活质量。

通过在纤维化发生过程中对胶原蛋白施加剪切力,可以控制单个胶原原纤维的组织或各向异性,以产生具有纳米级特征的高度对齐或随机图案原纤维的支架。这些特征可以沿原纤维的方向指导细胞相互作用和细胞骨架组织。该协议可以制造具有纳米级纤维图案的生物材料,而无需昂贵的专用设备或试剂。
