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 (ACM) 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.
Rat ACM is a liquid medium prepared from primary rat astrocyte cultures by using astrocyte medium (Cat #1801) 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.

后，转移细胞悬液至新瓶中，加入DMEM/F12完全培养基，在37ºC, 5%CO2培养箱中培养9天（每3天更换培养液一次），第9天将培养瓶置于恒温旋转摇床上37ºC, 240rpm，摇18小时，去掉悬浮的细胞，用D-Hanks液清洗3次，进行传代培养即得纯化的星形胶质细胞。经免疫细胞化学法检测，98%以上的细胞GFAP免疫反应为阳性。
在细胞生物学领域，原代细胞培养作为解开生命奥秘的重要工具，要求实验者遵循一系列关键的注意事项以确保可靠的实验结果。 本文将深入探讨如何在原代细胞培养过程中应用这些关键要点： 原代培养要重点注意无菌操作，所用器械需提前高压灭菌； 鼠胚原代培养时，获取组织较少，建议在冷光源体视显微镜下操作； 原代细胞培养过程比较慢，培养时间最少需要一周的时间。若 2 天后可能会出现培养基变黄的现象，且无漂浮物，排除污染，属于正常现象。这是因为细胞在贴壁生长过程中释放了 CO2 和其他物质导致培养液 PH
机械性损伤导致细胞死亡等缺点。本实验采用视神经组织块培养的方法，对新生大鼠的视神经胶质细胞进行条件化原代培养，利用少突胶质细胞和星形胶质细胞生长条件的不同，采用条件培养基纯化2种细胞。少突胶质细胞和Ⅱ型星形胶质细胞是从一种普通双潜能的少突胶质细胞－2型星形胶质细胞祖细胞（oligodendrocyte-type-2astrocyte progenitor cell，O2A）发育而来。大鼠出生后约1周，少突胶质细胞逐渐成熟。因此，从新生大鼠取材可获得O2A祖细胞。体外研究发现甲状腺素、胰岛素、转铁
