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。

Comparison of the chondrosarcoma cell line SW1353 with primary human adult articular chondrocytes with regard to their gene expression profile and reactivity to IL-1beta
In this study, the human chondrosarcoma cell line SW1353 was investigated by gene expression analysis in order to validate it as an in vitro model for primary human (adult articular) chondrocytes (PHCs). PHCs and SW1353 cells were cultured as high density monolayer cultures with and without 1 ng/ml interleukin-1β (IL-1β). RNA was isolated and assayed using a custom-made oligonucleotide microarray representing 312 chondrocyte-relevant genes. The expression levels of selected genes were confirmed by real-time polymerase chain reaction and the gene expression profiles of the two cell types, both with and without IL-1β treatment, were compared. Overall, gene expression profiling showed only very limited similarities between SW1353 cells and PHCs at the transcriptional level. Similarities were predominantly seen with respect to catabolic effects after IL-1β treatment. In both cell systems matrix metalloproteinase-1 (MMP-1), MMP-3 and MMP-13 were strongly induced by IL-1β, without significant induction of MMP-2. IL-6 was also found to be up-regulated by IL-1β in both cellular models. On the other hand, intercellular mediators such as leucemia inhibitory factor (LIF) and bone morphogenetic protein-2 (BMP-2) were not induced by IL-1β in SW1353 cells, but significantly up-regulated in PHCs. Bioinformatical analysis identified nuclear factor kappa-B (NFκB) as a common transcriptional regulator of IL-1β induced genes in both SW1353 cells and PHCs, whereas other transcription factors were only found to be relevant for individual cell systems. Our data characterize SW1353 cells as a cell line with only a very limited potential to mimic PHCs, though SW1353 cells can be of value to study the induction of protease expression within cells, a phenomenon also seen in chondrocytes.
The cucurbitacins E, D and I: Investigation of their cytotoxicity toward human chondrosarcoma SW 1353 cell line and their biotransformation in man liver
Cucurbitacins are a class of natural compounds known for their numerous potential pharmacological effects. The purpose of this work was to compare the cytotoxicity of three cucurbitacins I, D, E on the chondrosarcoma SW 1353 cancer cell line and to investigate their biotransformation in man. Cucurbitacins I and D showed a very strong cytotoxicity, which was higher than that of cytochalasin D, used as a drug reference. Almost 100% of the cells were apoptotic as observed by DNA fragmentation (TUNEL assay) after 12 h with cucurbitacins I and D (1 μM) and cucurbitacin E (10 μM). In terms of IC50 values, cucurbitacins I and E presented a higher toxicity compared to that of cucurbitacin D (MTT assay). Cucurbitacin E was readily hydrolyzed by human hepatic microsomes, leading to cucurbitacin I (Km 22 μM, Vmax 571 nmol/mg proteins/min). On the other hand, the three cucurbitacins were hydroxylated at a very low extent, but they were sulfated and glucuronidated. In terms of Vmax/Km, the cucurbitacin E was the best substrate of UDP-glucuronosyltransferases. This study shows that cucurbitacins I, D and E present a potent cytotoxic activity toward the chondrosarcoma SW 1353 cell line and are metabolized as sulfate and glucuronide conjugates.

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.
