Abstract
本发明公开了一种稳定的原代肝细胞试剂盒的生产方法。通过灌注和消化、提取、纯化、培养获得的原代肝细胞,保存在下列保存液中:10‑40%的胎牛血清、8‑12%的二甲基亚砜、2‑5%的磺基水杨酸、5‑10%的乙酰胺、4‑10%的螺旋藻多糖、0.5‑2%的青链霉素、10‑20%的甘油、0.5‑3%的牛磺酸、6‑11%的肌醇半乳糖苷,以磷酸缓冲液磷酸二氢钾、磷酸氢二钠调pH值至7.2‑7.4。本发明制成的原代肝细胞试剂盒,保存时间更长,运输方便,在复苏后即可应用。可方便和广泛用于各项相应研究。
Description
技术领域
本发明属于医学生物技术领域,涉及原代肝细胞分离、纯化、培养及稳定的试剂盒生产方法。
背景技术
肝脏是身体内以代谢功能为主的一个器官,并在身体里面起着去氧化、储存肝糖、分泌性蛋白质的合成等作用。肝脏相关疾病及其代谢的研究,可以通过从肝组织获得正常的原代肝细胞,实现离体研究。且离体原代培养的肝细胞不受到体内神经内分泌系统的复杂影响,还能够保持肝细胞的特异性功能。可以更多更方便地用于药物研发、疾病研究和环境安全研究等。
原代肝细胞主要是肝实质细胞,肝实质细胞是指具有肝功能的单位,是肝脏的基本组成单位之一。目前有多个专利公开了原代肝细胞的分离方法和培养方法。
但肝实质细胞属于中高度分化细胞,生长营养需求高,在体外存活时间短;每次使用之前,需要临时分离和培养,对于很多缺乏相应设备的试验室无法进行,且因临时分离和培养的操作技术差异等,造成数据不稳定。因此,本发明开发一种稳定型的原代肝细胞试剂盒,可供研究人员方便使用。
发明内容
本发明主要内容和关键点如下:
1、小鼠肝灌注和消化:以蠕动泵进行灌注。消化期间定期按压下腔静脉,这种方法可以使肝脏反复膨胀,肝内增加的压力有助于肝脏的消化,从而提高产率。
2、肝细胞提取:在肝脏溶解在分散液后,用镊子夹住肝脏的中央部位,轻轻摇动以分散残留的细胞,丢弃所有残留的固体颗粒。
3、肝细胞纯化:以预冷培养基溶解细胞团,重悬,离心3次。
4、肝细胞培养:在将细胞放入培养箱之前,以线性方式(即直线前后或左右)彻底震板。在培养4h后,铺上层胶原蛋白以形成三明治夹层培养。以后分别每24h换液,连续培养3天。
5、原代肝细胞试剂稳定液生产:保存液主要成份及配比:10-40%的胎牛血清、8-12%的二甲基亚砜、2-5%的磺基水杨酸、5-10%的乙酰胺、4-10%的螺旋藻多糖、0.5-2%的青链霉素、10-20%的甘油、0.5-3%的牛磺酸、6-11%的肌醇半乳糖苷。以磷酸缓冲液磷酸二氢钾、磷酸氢二钠调pH值至7.2-7.4,4℃保存。
6、细胞活性检测及连续性检测:对存储的试剂盒肝原代细胞进行复活,以台盼蓝染色法和MTT法检测细胞活性。
附图说明
图1是每个试剂盒肝细胞连续6个月的计数板计数。
图2是台盼蓝染色法活性测定结果不同时间的肝细胞活率。
图3是MTT法活性测定结果OD值。
具体实施方式
为了更清楚明白本发明,将结合实施的具体例子进行详细描述和说明。此处所描述的具体实施例仅仅用以解释本发明,并不应视为限制本发明的范围。尤其是一些试剂的具体配比,无法全部列出,但也在本发明范围之内。同时描述的部分具体实施方式为常规条件进行。
具体实施步骤1、小鼠肝灌注和消化:
麻醉小鼠。1.25%三溴乙醇0.13-0.15ml/10g,腹腔注射。腹部向上将小鼠固定于工作平台上;胶带固定四肢。用75%酒精清洁、消毒腹部和胸部区域。用剪刀和镊子取下腹部切口,剪开表皮,拨开到一边,直线剪开肌肉层至剑突,将肌肉层拨开。用棉球拨开腹腔其他脏器,使肝脏、门静脉(PV)和下腔静脉(IVC) 充分暴露。启动蠕动泵,等待套管针前端有液体流出后,伴随着液体的流出,迅速地将套管针置入门静脉中。当剪断下腔静脉后,将灌流速度加大到5ml/min。当灌注液即将耗尽时,打开消化液管道阀门。消化期间定期按压下腔静脉,这种方法可以使肝脏反复膨胀,肝内增加的压力有助于肝脏的消化,从而提高产率。在肝下叶或许会看到小的清亮透明的部分,肝脏可能出现湿透的条纹布样纹理。当消化效果满意后,关掉蠕动泵并小心地拔出套管。
具体实施步骤2、肝细胞提取:
用新的镊子和剪刀小心取下肝脏,立即将肝脏浸入盛有4℃预冷DMEM的10cm 培养皿中,撕裂肝叶。肝脏可以大部分溶解在分散液之中。将肝脏撕开后,用镊子夹住肝脏的中央部位,轻轻摇动以分散残留的细胞。丢弃所有残留的固体颗粒。
具体实施步骤3、肝细胞纯化:
用100μm滤网过滤细胞悬浮液。然后将其转移到无菌、干净的50ml离心管中。300rpm、4℃离心3分钟。用移液管吸弃上清,加入10mL4℃预冷WE培养基。轻轻吹打几次以溶解底部的细胞团,并重悬。再重复上述步骤2次,共计离心3 次。离心完成后,吸弃上清,并加入10ml冷培养基。保持足够的细胞悬液浓度,这样就不必在细胞铺板之前重新离心,但也不要使细胞悬液浓度过高,以免造成计数困难。轻柔重悬细胞。
具体实施步骤4、肝细胞培养:
在计数细胞后,对铺板细胞悬液进行适当稀释。在确认细胞密度正常并进行过各种必要的调整后,将细胞种在铺好下层1型胶原蛋白的孔板中。种板时确保每1-2分钟重悬一次细胞,因为肝细胞密度较大、沉淀迅速。在将细胞放入培养箱之前,以线性方式(即直线前后或左右)彻底震板。提前铺好下胶,保存在细胞培养箱中,使用前用PBS缓冲液小心洗板1次,本实验培养液均为无血清 William’s E培养液,添加培养液至2ml,在放入培养箱培养时注意震板摇匀,培养4h后,铺上层胶原蛋白以形成三明治夹层培养,不另加培养基。以后分别每24h换液。连续培养3天。
具体实施步骤5、原代肝细胞试剂稳定液生产:
弃去培养基,对贴壁细胞以下列保存液进行冲洗,然后将其转移到无菌、干净的50ml离心管中。300rpm、4℃离心2分钟。用移液管吸弃上清,加入20-30ml 保存液,密封保存。
保存液主要成份及配比:10-40%的胎牛血清、8-12%的二甲基亚砜、2-5%的磺基水杨酸、5-10%的乙酰胺、4-10%的螺旋藻多糖、0.5-2%的青链霉素、 10-20%的甘油、0.5-3%的牛磺酸、6-11%的肌醇半乳糖苷。以磷酸缓冲液磷酸二氢钾、磷酸氢二钠调pH值至7.2-7.4,4℃保存。
具体实施步骤6、细胞复苏和细胞活性检测:
将冻存保存的肝细胞,置于37℃水浴锅中迅速解冻,加以直接加入到复苏培养基中,或者再经过离心,去掉上清,加入复苏培养基进行重悬。
复苏后,检查细胞活性,所复苏的肝细胞活力应至少超过85%,以确保不同实验批次间的一致性,连续检查6个月。
台盼蓝染色法:向100μl细胞悬浮液中加入800μl培养基或PBS,再添加 100μl0.4%的台盼蓝。上下摇动几次使其与细胞悬液充分混合。室温染色约 1min。再次轻柔吹打数次,吸取10μl悬液滴加到血细胞计数板上。显微镜下计数所有未蓝染、非空泡样细胞。活的、健康的肝细胞具有明亮,清澈,平滑的外观,相对较小并且有聚集性。受损、死亡的细胞通常肿胀并且看起来粗糙、呈颗粒状。
MTT法:取细胞悬液,以1x10个/孔(100LL)接种于96孔培养板中。待 24h贴壁后,弃去原培养基。在37℃,5%C02条件下继续培养24h,每孔加入 200μl MTT储存液(5g/L-1),孵育4h后弃培养基,每孔加100μl DMSO,振荡5min,在酶标仪570nm处测定吸光度(OD值)。
上述实施例的说明只是用于理解本发明的方法及其核心思想。应当指出,对于本领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以对本发明进行若干改进和修饰,这些改进和修饰也将落入本发明权利要求的保护范围内。
