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MEMa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。

Chronological expression of microtubule-associated proteins (MAPs) in EC cell P19 after neuronal induction by retinoic acid.
Pluripotent murine embryonal carcinoma (EC) P19 cells are induced at a high rate into neural cells using retinoic acid and serum-free medium. EM observation revealed great increase of microtubules (MTs) after neuronal induction. To study the expression of microtubule-associated proteins (MAPs), immunoblotting and immunocytochemistry were performed with phosphorylated MAP1B (pMAP1B)-, MAP2-, and MAP1A-specific monoclonal antibodies. They did not stain undifferentiated cells. Early MAPs (pMAP1B and MAP2C) appeared 12 h after the neuronal induction, changing to late MAPs (MAP1A and MAP2A/B) at 3–5 days. These expression patterns are quite similar to those of neural cells in vivo. Anti-pMAP1B stained not only neurites but also the cell body and varicosities. But after extraction of the soluble component by permeabilization, pMAP1B was found in only MT-domains of the neurites at LM and EM levels, indicating that some part of pMAP1B is a structural component of neurite MTs and others exist in a soluble form. After culturing for more than 5 days, pMAP1B disappeared from the soma, but still remained in the distal ends of neurites. Here we showed that P19 is a good model system for studying the expression of MAPs on the continuous course of neuronal differentiation.
Different Transcription Factors Regulate nestin Gene Expression during P19 Cell Neural Differentiation and Central Nervous System Development
Nestin is a molecular marker for neural progenitor cells. Rat and human nestin genes possess a central nervous system-specific enhancer within their second introns. However, the transcription factors that bind to the nestin enhancer have not been fully elucidated. Here, we show that the second intron of the mouse nestin gene is sufficient to drive reporter gene expression in the developing nervous system. The core sequence of this central nervous system-specific enhancer localizes to the 3′ 320-bp region. The cis -elements for Sox and POU family transcription factors and the hormone-responsive element are essential for nestin expression during embryonic carcinoma P19 cell neural differentiation and in the developing chick neural tube. Interestingly, different transcription factors bind to the nestin enhancer at different stages of P19 cell neural differentiation and central nervous system development. Sox2 and SF1 may mediate basal nestin expression in undifferentiated P19EC cells, whereas Sox2, Brn1, and Brn2 bind to the enhancer in P19 neural progenitor cells. Similarly, in vivo , Oct1 binds to the nestin enhancer in embryonic day 8.5 (E8.5) mouse embryos, and Oct1, Brn1, and Brn2 bind to this enhancer in E10.5 and E12.5 mouse embryos. Our studies therefore suggest a temporal coordination of transcription factors in determining nestin gene expression.

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.
