养科研细胞是生物医学研究的基本功。有三个小经验可以和大家分享一下:1)不要烧瓶口。大多数人都喜欢在酒精灯的火焰上关瓶子,觉得这样可以避免污染。不知道大家是不是有培养基怎么越用越发紫的困惑?知道为什么吗?烧瓶口烧的。培养基一般都是用碳酸/碳酸氢跟作缓冲体系。瓶口在火焰上的时候,炽热的空气进入瓶内。塞紧塞子放入冰箱后,空气变冷,压力骤降,培养基中的碳酸就会转化成二氧化碳,释放出来。培养基中的碳酸少了,当然会变碱。如果不烧瓶口的话,你会发现培养液变碱的速度会大大减慢。(当然多多少少还是会有一点越用越碱,因为室温还是比冰箱内的温度高),其实烧瓶口防止污染纯粹是心理安慰。不妨试一下把手指在火上晃几下,你会发现根本就不会烧疼。如果有细菌的话,这么晃两下也烧不死多少。要想烧死全部细菌,除非把瓶口和塞子烧红。我在国内从来就不烧瓶口。来美国以后发现这里更彻底,超净台内根本就不点酒精灯;2)不要频繁看细胞。对于初学者而言,养细胞就像养孩子一样,有空就要去看看。细胞越是养不好,就越是经常去看。实际上看细胞对细胞的生长没有任何好处,特别是对原代细胞或是免疫磁珠分选后,密度特别低的细胞。培养基中的生长因子是非常有限的。细胞好不容易自分泌一点儿促生长的因子在其周围,形成有利于生长的局部环境。你跑去看细胞,培养瓶这么一晃,把因子都给晃散了。经常可以看到新手一天到晚都在看细胞,细胞老是长不好。老手细胞一扔好几天不管,细胞疯长;3)不要怕消化。在传代的时候,初学者往往生怕细胞消化过度,早早地终止消化。细胞没下来就使劲吹灯,吹得满瓶子都是气泡。在我看来,用力吹打对细胞的损伤比消化更大。我师兄在做血管平滑肌原代的时候,37度消化过夜,细胞也没事。我一般是等细胞完全变圆后才中止消化。细胞轻轻一晃就能下来。还有,动作要轻柔,尽量不要产生气泡。气泡在破裂时的机械应力相当大,对细胞的伤害也是很大的。

体内细胞培养及其操作步骤:【瘤细胞悬液接种】1)无菌选取生长良好(有光泽,淡红色)瘤组织或对数生长期培养瘤细胞;2)在PBS中将瘤组织剪碎后用匀浆器研磨,经80~100目筛网过滤成细胞悬液;3)培养细胞应用PBS洗两遍;4)计数并调整细胞浓度至107~108/ml;5)常规消毒后,于接种部位(通常为背部或腋窝腹股沟皮下)用医用注射器皮下潜行一段后注入细胞悬液(0.1ml/部位,>106细胞)。初次接种成功率低,细胞数尽可能多一些;6)次日注意观察动物一般情况。初次接种一般有一段较长的潜伏期,以后随着传代潜伏期逐渐缩短,固定为一个相对稳定的时间。【腹水瘤的建立与腹水瘤的接种】将实体瘤细胞直接种于小鼠腹腔、腹壁或其他部位,引起腹水,腹水中含有瘤细胞,将这种腹水反复传代,即可成为腹水瘤。初次传代时,腹水常呈血性(含大量红细胞),反复传代后腹水逐渐变成乳白色。腹水瘤的接种过程如下。1)将冻存或培养的腹水瘤细胞离心和洗涤,进行细胞计数;2)消毒动物,左下腹穿刺接种106腹水瘤细胞;3)接种腹水瘤细胞后约7~12d,待小鼠腹部明显膨大。用碘酒棉球消毒小鼠腹部,用9号针头抽取腹水,也可行腹部解剖后,用滴管吸取。每只小鼠可抽3~5ml;4)抽取的腹水经3000rpm离心15min,收集上清,分装冻存备用。
