巨噬细胞原代培养方法及步骤。
原代神经细胞培养试验方法及步骤。
神经细胞(神经元)不易培养,只有在适宜情况下,如接种在胶原底层上,或加入神经生长因子和胶质细胞因子时,可出现一定程度的分化,长出突起等现象,但很难使之增殖。而神经胶质细胞是神经组织中比较容易培养的成分。 人、鼠等脑组织即可用于神经胶质细胞培养,不仅能获得生长的胶质细胞,也可形成能传代的二倍体细胞系。
内皮细胞易于从大血管分离培养成单层细胞,对于研究内皮细胞再生、肿瘤促血管生长因子(tumor angiogenesis factor,TAF)等有很大价值。 以人脐带静脉灌流消化法为例说明培养方法及步骤。
1. 液体培养基的保存是冷藏好?还是冷冻好? 要冷藏!因为液体培养基经冷冻后再经溶化时,其溶液的pH值会发生改变,溶液往往变碱,某些成分溶解也会受到影响对细胞生长不利。故液体培养基一定要存放在冷藏箱中,通常液体培养基在冷藏条件下可存放6个月 ~ 一年。 2. 液体培养基中谷氨酰胺的作用,及使用方法。 几乎所有的细胞对谷氨酰胺有较高的要求,细胞需要谷氨酰胺合成蛋白质,在缺少谷氨酰胺时,细胞生长 ...
无菌操作基本技术 1. 实验进行前,无菌室及无菌操作台(laminar flow) 以紫外灯照射30-60分钟灭菌,以70%ethanol 擦拭无菌操作抬面,并开启无菌操作台风扇运转10分钟后,才开始实验操作。每次操作只处理一株细胞株,且即使培养相同亦不共享培养基,以避免失误混淆或细胞间污染。实验完毕后,将实验物品带出工作台,以70 % ethanol 擦拭无菌操作抬面。操作间隔应让无 ...

细胞计数 实验原理:当待测细胞悬液中细胞均匀分布时,通过测定一定体积悬液中的细胞的数目,即可换算出每毫升细胞悬液中细胞的细胞数目。 具体操作:一.准备工作: 取一瓶传代的细胞,按照《传代细胞培养(消化法)》中的传代方法繁殖细胞,待长成单层后以被使用。 二.细胞悬液制备:细胞悬液的制备方法是用0.25%的胰蛋白酶液消化、PB ...
个别组织细胞的培养 体内组织细胞在体外培养时,所需培养环境基本相似,但由于物种、个体遗传背景及所处发育阶段等的不同,各自要求条件有一定差别,所采取的培养技术措施亦不尽相同,现介绍个别组织细胞培养的要点如下: 一、上皮细胞培养 上皮细胞包括腺上皮是很多器官如肝、胰、乳腺等的功能成分,又由于癌起源于上皮组织,故上皮细胞培养特别受到重视。但上皮细胞培养中常混杂有成纤维细胞,培养时生长速度往往超过上皮细胞 ...
