Astrocytes are the most abundant cells in the central nervous system (CNS). Astrocytes provide a variety of biological functions, such as supporting endothelial cells involved in blood-brain barrier formation, providing nutrients to neurons, maintaining extracellular ion balance, and promoting repair in the CNS. Astrocyte conditioned medium-serum free (ACM-sf) has been widely used to support the growth of neurons and endothelial cells in culture. ACM has also been shown to protect neurons from corticosterone-induced damage.
ACM-sf is a liquid medium prepared from primary human astrocyte cultures by using astrocyte medium (Cat #1801) without serum conditioned for 48 hours. The medium is sterile filtered and has a pH of 7.4 when equilibrated in an incubator with an atmosphere of 5% CO2/95% air.

【求助】请教!我用无血清培养基养的胃癌原代细胞,为什么会出现这种小颗粒?
暮色英雄 我是用无血清NB培养基+EGF+bFGF+B27+p/s双抗的培养基培养的胃癌原代细胞,培养基已经用0.22μm过滤器过滤除菌,但是培养细胞之后出现很多小颗粒,不知道是什么东西,这照片是昨天照的,今天再观察的时候这些小颗粒已经长满了,我师姐帮我看了说是污染,然后我把细胞倒掉了,但是她也不知道这是什么污染。希望各位大侠能帮小弟看看这到底是不是污染,是什么东西?谢谢了 这是20x镜拍
首先,从细胞的培养过程下手。外泌体来自细胞,因此必须先从源头抓起。大部分的细胞培养过程中都是带有血清的,无论是牛血清、马血清等都是含有异源外泌体的,而我们研究的目标通常是细胞所分泌的外泌体,因此需要尽可能的去除这些异源外泌体的干扰。那么我们需要怎么做呢? 这里需要了解一个大原则:在细胞正常生长的条件下,尽可能的减少血清外泌体或者不使用血清。方法一,可以通过超速离心的方法去除血清中外泌体。方法二,通过外泌体专用无血清培养基来替代完全培养基,维持细胞
上清液。 PBS重悬的外泌体初始液 12,000 g,2 min 离心 2-3 次至无明显沉淀,每次离心收集上清液,上清液再进行EPF柱纯化。 建议:细胞培养使用低血清或者无外泌体血清或者外泌体专用无血清培养基,培养时间控制在24 - 48 h 左右 ,收集上清液时培养基颜色正常,不要等到偏黄色时再收集上清液。 11、EPF柱是否可以多次使用? 不能重复使用。过量的样品会超出纯化柱的使用极限,会严重影响分离效果。 12、外泌体如何保存? 纯化后的外泌体可于 4℃ 保存不超过一周,-80℃ 条件下可长期
