Dent Mater J:EDTA处理过的牙本质对小鼠iPS细胞体内外成骨/成牙本质分化的影响

2019-08-04 lishiting MedSci原创

这篇研究的目的是为了评估EDTA处理过的牙本质对小鼠诱导的多能(iPS)干细胞分化的影响。

这篇研究的目的是为了评估EDTA处理过的牙本质对小鼠诱导的多能(iPS)干细胞分化的影响。研究从牛切牙获取牙本质片并施以17% EDTA刺激。将来源于小鼠iPS细胞形成的胚胎体(EBs)培养于牙本质片上以备后续试验。体外扫描电镜(SEM)结果显示,EDTA处理过的牙本质表面粗糙度、Sa和Sdr较高,并且可观察到胶原原纤维样结构。RT-PCR结果显示,实验组成骨细胞标记物Bsp和Ocn的mRNA表达水平明显增高。免疫荧光(IF)检测发现,实验组DMP1, DSP和BSP蛋白表达水平更加显著。体内研究显示,在EDTA处理过的牙本质附近可观察到软骨和骨样结构。这篇研究表明,施以17% EDTA处理过的牙本质能够诱导小鼠iPS细胞的成骨/成牙本质分化。原始出处:Ser-Od T, Al-Wahabi A, et al.

史上首次:日本确认iPS视细胞能让眼睛恢复感光

据日媒报道,日本理化学研究所多细胞系统形成研究中心(位于神户市)的研究小组在本月10日的美国科学杂志网络版上发表一项研究成果,确认iPS视细胞能让眼睛恢复感光。 据报道,结果显示,研究者让诱导多能干细胞(iPS细胞)变为视网膜的视细胞,并移植到因晚期“视网膜色素变性症”失明的老鼠眼中,结果老鼠变得眼睛能够感光了。这是首次确认使用ips细胞能够恢复感光功能。 副项目带头人万代道子解释说
