本公司的细胞培养操作规程，供参考
一、培养基及培养冻存条件准备：
- 准备H-DMEM培养基，90%；优质胎牛血清，10%。
- 培养条件： 气相：空气，95%；二氧化碳，5%。 温度：37℃，培养箱湿度为70%-80%。
- 冻存液：90%血清，10%DMSO，现用现配。液氮储存。
对于贴壁细胞，传代可参考以下方法：
- 弃去培养上清，用不含钙、镁离子的PBS润洗细胞1-2次。
- 加2ml消化液（0.25%Trypsin-0.53mM EDTA）于培养瓶中，置于37℃培养箱中消化2-3分钟，然后在显微镜下观察细胞消化情况，若细胞大部分变圆并脱落，迅速拿回操作台，轻敲几下培养瓶后加入3ml此细胞的培养基终止消化。
- 轻轻吹打后吸出，移入15ml离心管中，在1200RPM条件下离心5分钟，弃去上清液，加入1mL培养液后吹匀。
- 移入到事先准备好的含有5ml培养基的T-25培养瓶中或含有14ml培养基的T-75培养瓶中培养。
3）细胞冻存：待细胞生长状态良好时，可进行细胞冻存。贴壁细胞冻存时，先要消化处理并进行细胞计数。消化方法按照细胞传代方法的1-3步骤进行，最后的重悬液使用血清。悬浮细胞直接计数后离心，用血清重悬浮，加DMSO至最终浓度为10%。加入DMSO后迅速混匀，按每1ml的数量分配到冻存管中。本公司按每个冻存管细胞数目大于1X106个细胞冻存。

cDNAs of cell adhesion molecules of different specificity induce changes in cell shape and border formation in cultured S180 cells.
The liver cell adhesion molecule (L-CAM) and N-cadherin or adherens junction-specific CAM (A-CAM) are structurally related cell surface glycoproteins that mediate calcium-dependent adhesion in different tissues. We have isolated and characterized a full-length cDNA clone for chicken N-cadherin and used this clone to transfect S180 mouse sarcoma cells that do not normally express N-cadherin. The transfected cells (S180cadN cells) expressed N-cadherin on their surfaces and resembled S180 cells transfected with L-CAM (S180L cells) in that at confluence they formed an epithelioid sheet and displayed a large increase in the number of adherens and gap junctions. In addition, N-cadherin in S180cadN cells, like L-CAM in S180L cells, accumulated at cellular boundaries where it was colocalized with cortical actin. In S180L cells and S180cadN cells, L-CAM and N-cadherin were seen at sites of adherens junctions but were not restricted to these areas. Adhesion mediated by either CAM was inhibited by treatment with cytochalasin D that disrupted the actin network of the transfected cells. Despite their known structural similarities, there was no evidence of interaction between L-CAM and N-cadherin. Doubly transfected cells (S180L/cadN) also formed epithelioid sheets. In these cells, both N-cadherin and L-CAM colocalized at areas of cell contact and the presence of antibodies to both CAMs was required to disrupt the sheets of cells. Studies using divalent antibodies to localize each CAM at the cell surface or to perturb their distributions indicated that in the same cell there were no interactions between L-CAM and N-cadherin molecules. These data suggest that the Ca++-dependent CAMs are likely to play a critical role in the maintenance of epithelial structures and support a model for the segregation of epithelia based on differences in specificity of CAM mediated binding. They also provide further support for the so-called precedence hypothesis that proposes that expression and homophilic binding of CAMs are necessary for formation of junctional structures in epithelia.
Comparison of anthracycline concentrations in S180 cell lines of varying sensitivity
Sublines of sarcoma 180 (S180) of varying sensitivity to adriamycin (ADR) have been selected in culture. The degree of resistance of these sublines ranged from 6- to 125-fold above that of parent S180 cells. ADR-resistant sublines demonstrated comparable degrees of cross-resistance to daunomycin (DNR), marcellomycin and AD 32, but each subline showed a uniform degree of tolerance toward actinomycin D and vincristine. Compared to the anthracycline-sensitive parent tumor, a 40% decrease in the intracellular steady-state level of [ 3 H]-daunomycin was observed in all sublines regardless of the degree of resistance. The level of cell-associated DNR and ADR observed after administration of equipotent concentrations of drug was different for each cell line and increased in proportion to the drug concentration. Thus, altered drug permeability appeared to be of minimal importance in the expression of high levels of resistance. In addition, the extent of DNR metabolism by the anthracycline-resistant sublines was not sufficiently different from that seen in parent S180 cells to account for the observed tolerance to these agents.

文献和实验Chicken intestinal epithelial cells were obtained from NEWGAINBIO company. Cells were cultured on 37℃, with 5% CO2, in the Ham’s F-12 Nutrient (DMEM/12) that contained the following supplementations: fetal bovine serum (5%), in-sulin (5 µg/mL), transferrin (5 µg/mL), selenium (5 ng/mL), epidermal growth factor (5 ng/mL) and penicillin-streptomycin (100–100 U/mL) for cell culturing (full DMEM/12). Experiments were performed with chicken intestinal epithelial cells and working solutions were prepared with plain DMEM/12 without supplementation. For the investigations, cells were seeded onto 96-well, 24-well or 6-well polystyrene cell culture plates.
Primary hVICs (passage 2) were cultured to 50–60% confluence and infected with pGMLV-SV40T-puro lentivirus (NewgainBio, Wuxi, China) at a multiplicity of infection of 80 supplemented with 5 µg/mL polybrene (Sigma-Aldrich, Buchs, Switzerland).
Tissue was cultured until cells became visible around the tissue, and when the fusion reached 90% (FIGURE 1A) §ask ¦lled with the prepared culturing medium was sent to the company for further immortalisation. Cell immortalisation was done for cell stability and longer-term use. Immortalised cells were cultured with 10% FBS and 1% PS in the DMEM medium. After the cells multiplied and merged, they were routinely passed and grown ( NEWGAINBIO Inc. Wuxi, Jiangsu, China) (FIGURE 1B-C).
Mouse primary cultured renal vascular ECs and VSMCs were obtained from Newgainbio company, which were tested by Factor VIII and α-smooth muscle actin (α-SMA), the marker of ECs and VSMCs. RNeasy Mini Kit was used for RNA extraction, and the above protocols were repeated.
Porcine primary colon epithelial cells (Newgainbio company, Wuxi,China) were cultured in Dulbecco's Modified Eagle's Medium (Solarbio, Beijing, China) containing 10 % fetal bovine serum (BioInd, Kiryat shmona, Lsrael) at 37 ◦C and 5 % CO2 humidity.
抗肿瘤药物是现在研究的一个热点问题，但是由于该模型的建立具有一定的技巧性，有不少刚刚开始做这方面实验的战友一般实验总会碰到这样那样的问题，本人硕士期间有幸参加过一类抗癌新药的研发工作，对小鼠肿瘤模型有一定的了解，把我在肿瘤造模实验中的一点心得写出来。动物选择： KM小鼠，裸鼠，C57 等均可作为，但是个人认为KM能做出来最好，毕竟比较有普遍性，还是正常生理状态的健康动物，比较有说服力，还便宜，裸鼠或者其他特定品种，比较适合特定的瘤株瘤株类型： H22 ; S180; EAC 等关于肿瘤细胞
