医疗发展又有新突破!法国科学家声称,他们在实验室培育了人类体外精子,这是世界上第一次成功的案例,未来将可用来治疗男性不孕症。

以前曾有科学家培育出健康完整的老鼠精子,但人类精子还是头一遭。他们是从男人的睾丸中取出尚未成熟的精原细胞样本,然后变换遗传物质成为成熟的精子,并可以冷冻保存。

负责执行这个计划的法国Kallistem公司首席执行官伊莎贝尔(Isabelle Cuoc)表示:“我们的团队是世界上第一个发展可在体外完全形成精子的技术,并且有足够产量作为试管婴儿,这是一个重大的科学成果。”而目前公司计划在两年内进行人体实验,并努力筹资金,希望能带来突破性的治疗,真正造福不孕症病患。

Plos One:冷冻干燥法能够长期保存精子

长期以来,精子的保存一直使用液氮。近年来随着技术的提高,冷冻干燥法已经发展为一个新的精子保存方法。 通过冷冻干燥法来保存精子的优势在于,它能够被保存在4℃,并在室温环境下运输。 虽然已经知道许多动物精子成功的通过冷冻干燥来保存,但是使用这种方法来长期保存精子的可能性还没有被研究。 近日,来自日本京都大学的研究人员做了一个有趣的实验,他们把卵细胞与冷冻干燥的精子受精。结果发现,卵细胞与老鼠冷冻
