細(xi)(xi)胞培養(yang)技術(shu)(shu)(shu)屬于細(xi)(xi)胞工程(cheng)(cheng)范疇，細(xi)(xi)胞工程(cheng)(cheng)包括細(xi)(xi)胞融合技術(shu)(shu)(shu)、單克(ke)隆抗體(ti)的制(zhi)備、核移植技術(shu)(shu)(shu)（克(ke)隆）等,而這些技術(shu)(shu)(shu)中都有(you)細(xi)(xi)胞培養(yang)過程(cheng)(cheng),所以(yi)說細(xi)(xi)胞培養(yang)是生物學(xue)研(yan)究的zui基本技術(shu)(shu)(shu)之(zhi)一。

上海(hai)慧穎生物(wu)供應293AHEK293,人胚腎上皮(pi)細胞(bao)，進口胎牛血(xue)清培(pei)養(yang)，活性好、存(cun)活率(lv)高。隨著細(xi)胞(bao)生物學尤其是干(gan)細(xi)胞(bao)研究的(de)(de)快速發展(zhan)，在細(xi)胞(bao)治療領域已(yi)經(jing)(jing)進行了(le)大量的(de)(de)探(tan)索，取得了(le)一(yi)系列的(de)(de)令人振奮的(de)(de)成果(guo)，且部分基礎研究成果(guo)已(yi)經(jing)(jing)在心血管(guan)系統(tong)疾(ji)(ji)病(bing) 、神經(jing)(jing)系統(tong)疾(ji)(ji)病(bing)、肌肉骨骼(ge)相關疾(ji)(ji)病(bing)、糖尿病(bing)等。

養(yang)細胞經驗(yan)分(fen)享：

1.細(xi)胞(bao)(bao)形態觀察(cha)。細(xi)胞(bao)(bao)膜(mo)是每天必(bi)須觀察(cha)的(de)(de)，看是否清(qing)晰，細(xi)胞(bao)(bao)的(de)(de)死亡(wang)往往是從細(xi)胞(bao)(bao)膜(mo)的(de)(de)破裂開始的(de)(de)，早期的(de)(de)表現就是細(xi)胞(bao)(bao)膜(mo)某一點(dian)出現欠完整或者(zhe)毛發影。

2.細(xi)胞往往會有“抱團”現(xian)象(xiang)，抱團生長或死亡，個人認為應該勤換液或傳代，盡量避 免(mian)細(xi)胞抱團。

3.細(xi)胞生(sheng)長(chang)(chang)迅速，強烈建(jian)議(yi)用較大的培養(yang)(yang)瓶(ping)養(yang)(yang)，用小瓶(ping)養(yang)(yang)的話，換液不及時，很容易死 亡。細(xi)胞的生(sheng)長(chang)(chang)速度一(yi)(yi)般為(wei)2天左右就(jiu)需要傳(chuan)代，并且一(yi)(yi)般為(wei)一(yi)(yi)傳(chuan)三，或一(yi)(yi)傳(chuan)四。

4.培養液：1640|DMEM|MEM|IMDM|a-MEM培養液，1L一(yi)般加碳酸氫鈉2g，并加雙抗，胎牛血清(qing)濃度*為(wei)12%，zui低不低于(yu)10%，有些細(xi)胞(bao)對胎牛血清(qing)高(gao)度依賴，比如WRO細(xi)胞(bao)，HT-22細(xi)胞(bao)，HA-VSMC細(xi)胞，NK-92細(xi)胞等。培養液PH應調為7.20-7.40之間(jian)。

5.防(fang)污染(ran)。L-02細(xi)胞(bao)生長(chang)迅速，較少發生污染(ran)，但常規措施應該(gai)做好。比如無(wu)菌(jun)操作，酒精 消(xiao)毒等(deng)，培養瓶口建議過火，包括(kuo)瓶蓋，應過火4秒(miao)左右。

6.凍存。-20一小時，-80次夜(ye)，液氮長期保存。強烈建議液氮長期保存，盡(jin)量不要(yao)在-80長期 保存，死亡率(lv)很(hen)高。

7.復蘇。調節(jie)水浴箱溫度為42℃，并提前(qian)在試(shi)管(guan)內放置10倍培養(yang)液，使培養(yang)液溫度與室(shi)溫一 致(zhi)。1分(fen)(fen)鐘內融(rong)化細(xi)胞(禁止(zhi)搖晃(huang)凍存管(guan))，移取至(zhi)試(shi)管(guan)內，動(dong)作要輕，從試(shi)管(guan)管(guan)底開始慢慢上提 移液管(guan)，使細(xi)胞在培養(yang)液內分(fen)(fen)布(bu)均勻，離心，洗(xi)2次(ci)。
