光诱导

RESULTS: Fifty minutes after addition of inducing medium, under the optical microscope, BMSCs exhibited a typical morphology of perikaryon. Three hours later, most of cells became into bipolar or multipolar neuron-like cell appearance with cell bodies and processes.

Lines are induced on the surface of a photosensitive glass by focused femtosecond laser transverse writing with scanning velocity in a wide range of 40-1800 μm/s. The formed lines are analyzed using scanning electron microscope and optical microscope.

利用聚焦飞秒激光的横向直写方式，采用宽的扫描速度范围(40-1800 μm/s)，在光敏玻璃表面上诱导了直线结构，并扫描电子显微镜和光学显微镜分析了形成的直线，发现随着扫描速度不同，形成的直线具有三种不同的形貌。

This suggests that the membrane is the target of photodamage and the free redicals of lipids produce by HA photosensitization is probably the important factor that initiates the damage of DNA and causes cell death finally.

实验还表明HA加上光照后对细胞具有明显的杀伤作用，使细胞存活率显著降低，提示HA光敏作用靶部位是细胞膜，而引发的脂自由基等产物可能是诱导DNA等损伤，最终导致细胞死亡的重要因素。
