本视频演示了如何在小鼠胚胎干细胞体外分化胚体采用悬滴法进行。
干细胞具有显着的潜力发展成许多不同的细胞类型。当一个干细胞分裂时,每个新细胞的潜力仍然是一个干细胞,或成为另一个类型的细胞与一个更专业的功能,这是有前途的科学顶尖科学家研究细胞疗法来治疗疾病的可能性。当没有暂停antidifferentiation因素文化时,胚胎干细胞自发分化和形成立体的多细胞聚集。这些细胞聚集被称为胚体(EB)。悬滴文化是一种广泛使用的EB形成诱导方法。悬滴的圆形底部,使胚胎干细胞,它可以提供一个良好的环境,形成EBS mES细胞的聚集。在悬滴aggregatied的ES细胞的数量是可以控制的不同细胞的数量在最初的细胞悬液,将挂在培养皿的盖子下降。使用这种方法,我们可以再现的形式从同质分化的ES细胞的预定人数。
The disadvantages of hanging drop method are as follows: the liquid volume of a drop is limited to less than 50ul due to maintaining hanging drops on the lid by surface tension, and it’s impossible to change the medium for hanging drops. Observation of forming EBs in drops directly with microscopy is also very difficult during cultivation. Further more , the hanging drop method consists of two steps, therefore, a series of step of the hanging drop method may be troublesome.
