Biomaterial:高科技解决佛系90后脱发问题

脱发是此刻困扰无数佛系90后的人生难题。其实毛囊形态发生是由毛囊胚(HFG)上皮层和间充质层之间的相互作用触发的。

脱发是此刻困扰无数佛系90后的人生难题。其实毛囊形态发生是由毛囊胚(HFG)上皮层和间充质层之间的相互作用触发的。最近,来自横滨国立大学的研究人员开发了一种通过细胞自组织化来大规模制备HFG的方法。
研究人员将小鼠表皮和小鼠/人间充质细胞混合在悬浮液中,并将它们接种在定制设计的阵列板的微孔中。在3天的培养期中,细胞最初形成随机分布的单细胞聚集体,然后在空间上相互分离,表现出典型的HFG形态学特征。
这些自我分类的毛囊胚(ssHFGs)被证明能够在皮下移植到裸鼠背部时有效地产生毛囊和毛干。
在由透氧聚硅氧烷制成的微孔阵列芯片中,研究人员可以大规模制备大约5000个ssHFGs。研究人员证明,硅胶芯片底部的氧气供应的完整性对于ssHFG的形成和随后的毛发生长是至关重要的。
最后,将芯片上空间排列的ssHFG封装在水凝胶中,而后移植到裸鼠的背部皮肤中以保留它们的介入空间,可以生成空间排列的毛囊。
这种简单的ssHFG制备方法是用于改善目前毛发再生医学技术的有前途的策略。
