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MEM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。
注意事项：
1. 收到冻存管细胞后，若发现干冰已挥发干净、冻存管瓶盖脱落、破损及细胞有污染，请立即与我们联系。
2. 所有动物细胞均视为有潜在的生物危害性，必须在二级生物安全台内操作，并请注意防护，所有废液及接触过此细胞的器皿需要灭菌后方能丢弃。
3. 细胞用途：仅供科研使用。

Propolis changes the anticancer activity of temozolomide in U87MG human glioblastoma cell line
Background Propolis is a honey bee product which contains many active compounds, such as CAPE or chrysin, and has many beneficial activities. Recently, its anti-tumor properties have been discussed. We have tested whether the ethanolic extract of propolis (EEP) interferes with temozolomide (TMZ) to inhibit U87MG cell line growth. Methods The U87MG glioblastoma cell line was exposed to TMZ (10-100??M), EEP (10-100??g/ml) or a mixture of TMZ and EEP during 24, 48 or 72hours. The cell division was examined by the H3-thymidine incorporation, while the western blot method was used for detection of p65 subunit of NF-??B and ELISA test to measure the concentration of its p50 subunit in the nucleus. Results We have found that both, TMZ and EEP administrated alone, had a dose- and time-dependent inhibitory effect on the U87MG cell line growth, which was manifested by gradual reduction of cell viability and alterations in proliferation rate. The anti-tumor effect of TMZ (20??M) was enhanced by EEP, which was especially well observed after a short time of exposition, where simultaneous usage of TMZ and EEP resulted in a higher degree of growth inhibition than each biological factor used separately. In addition, cells treated with TMZ presented no changes in NF-??B activity in prolonged time of treatment and EEP only slightly reduced the nuclear translocation of this transcription factor. In turn, the combined incubation with TMZ and EEP led to an approximately double reduction of NF-??B nuclear localization. Conclusions We conclude that EEP presents cytotoxic properties and may cooperate with TMZ synergistically enhancing its growth inhibiting activity against glioblastoma U87MG cell line. This phenomenon may be at least partially mediated by a reduced activity of NF-??B.
Origin of the U87MG glioma cell line: Good news and bad news.
Human tumor-derived cell lines are indispensable tools for basic and translational oncology. They have an infinite life span and are easy to handle and scalable, and results can be obtained with high reproducibility. However, a tumor-derived cell line may not be authentic to the tumor of origin. Two major questions emerge: Have the identity of the donor and the actual tumor origin of the cell line been accurately determined? To what extent does the cell line reflect the phenotype of the tumor type of origin? The importance of these questions is greatest in translational research. We have examined these questions using genetic profiling and transcriptome analysis in human glioma cell lines. We find that the DNA profile of the widely used glioma cell line U87MG is different from that of the original cells and that it is likely to be a bona fide human glioblastoma cell line of unknown origin.

文献和实验1. 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.
2. 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).
3. 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).
4. 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.
5. 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.
