位於眼球前端、讓光綫進入眼睛的眼角膜,對「靈魂之窗」十分重要。早前日本大阪大學的眼科專家利用「誘導性多能幹細胞」(iPS細胞)培育出角膜細胞,為一名患有角膜病變的女病人進行移植,成功令她回復視力至不妨礙日常生活,成全球首例。

眼角膜
眼角膜是眼睛最前端一層透明薄膜,形狀如隱形眼鏡般。透明的眼角膜可讓光綫進入眼睛觀看影像。眼角膜容易因受損或感染而留下疤痕,嚴重的會引致失明。角膜細胞約0.03至0.05毫米厚,狀似薄膜。

The cornea, the front part of the eye that lets in light, is very important to our 'windows to the soul'. Recently, ophthalmologists at Japan's Osaka University used induced pluripotent stem cells (iPSCs) to give rise to corneal cells. The cells were transplanted to a female patient suffering from corneal disease, helping her to restore her eyesight and live a normal life again. This is the world's fi rst case.
