新华社东京6月14日电日本一研究团队在14日出版的美国《细胞.干细胞》杂志上发表的1份报告称,他们利用人类胚胎干细胞成功培育出立体的视网膜组织。日本理化学研究所的研究人员此前曾开发出使细胞团块漂浮在培养液中,进而自发地生成复杂结构的培养技术。2011年,以该所研究人员为中心的团队利用小鼠的胚胎干细胞,成功培育出拥有杯状结构,能发育成视网膜的视杯以及立体视网膜组织。 Xinhua News Agency, Tokyo, June 14 - A Japanese team published a report in the American “Cell Stem Cells” magazine published on the 14th that they successfully cultured three-dimensional retinal tissues using human embryonic stem cells. Researchers at the Japan Institute of Chemistry and Chemical Engineering have previously developed culture techniques that float cell masses in culture and spontaneously generate complex structures. In 2011, the team led by the researcher used mouse embryonic stem cells to successfully develop a cup with a cup-shaped structure that developed into a retina and a stereoscopic retinal tissue.
