Description

一种对食蟹猴干细胞的无饲养层培养方法
技术领域
本发明属于生物与新医药技术领域,尤其涉及一种对食蟹猴干细胞的无饲养层培养方法。
背景技术
目前,培养食蟹猴的多能干细胞培养都需要饲养层提供部分营养,饲养层由12.5天的小鼠胚胎制成,需要将CF-1品系的小鼠交配后在第12.5天取出胚胎,将内脏、四肢和头部去除后,将剩余的组织消化成单细胞培养,待细胞增殖,即可当作饲养层。因此饲养层的制备需要花费大量的人力物力,并且饲养层由于含有动物源成分,培养基成分不确定,容易产生性能不稳定的情况,造成前后批次结果不一致,培养基的质量不稳定和不规范,直接影响研究结果的准确性。在人的多能干细胞和小鼠的多能干细胞培养中,科学家为了解决饲养层带来的影响,开发了新的培养体系,可以满足在不需要饲养层的情况下培养人和小鼠的多能干细胞。但是截止目前为止,针对食蟹猴无饲养层干细胞培养的培养体系还没有较好的开发,因此,亟需一种新的对食蟹猴干细胞的无饲养层培养方法。
通过上述分析,现有技术存在的问题及缺陷为:现有饲养层的制备需要花费大量的人力物力,并且饲养层由于含有动物源成分,培养基成分不确定,容易产生性能不稳定的情况,造成前后批次结果不一致,培养基的质量不稳定和不规范,直接影响研究结果的准确性。
解决以上问题及缺陷的难度为:摸索一种新的培养方法需要较多的人力和物力,并且在专业知识上也需要有一定的储备。需要在培养体系的成份和浓度中进行较多的探索,因此需要对培养体系成份大量的筛查。
解决以上问题及缺陷的意义为:如果能解决食蟹猴干细胞无饲养层培养的难题,将有助于非人灵长类干细胞的开发,比如类器官的培养。也能为人多能干细胞的培养体系提供新的参考。
