产品介绍
细胞名称：猪小肠上皮细胞系
背景描述：猪小肠上皮细胞系的小肠组织是主要的消化细胞，它含有肠液，胰液和胆汁，分别都含有消化蛋白质、糖、和脂肪的酶，能对蛋白质、糖、脂肪进行消化，使之变为简单的物质，如氨基酸、葡萄糖、甘油三脂等，同时胆汁能对脂肪进行分解，促进脂肪的消化。因此营养物质主要在小肠被消化，是人体的主要消化器官。而小肠上皮细胞有分泌作用，所以研究小肠上皮细胞对研究小肠功能有重要意义。

Establishment and characterization of a spontaneously immortalized porcine mammary epithelial cell line
We have established a spontaneously immortalized porcine mammary epithelial cell line (SI-PMEC) from the mammary gland of a lactating sow and maintained it long-term in culture by continuous subculturing. SI-PMEC cells were maintained for more than 8 months (70 passages) in DMEM/F12 medium supplemented with 10% fetal calf serum, insulin, and hydrocortisone without obvious signs of senescence. When grown at low density on a plastic substratum, SI-PMEC cells formed islands, and when grown to confluency, the cells formed a monolayer and aggregated with the characteristic cobblestone morphology of epithelial cells. The subcultured SI-PMEC cells appeared to proliferate without changes in morphology or growth pattern, with an estimated population doubling time of 2022 h. With increasing density, SI-PMEC cells organized into lumen-like structures with elongated cells at the margins. SI-PMEC cells from stocks frozen at Passage 30 were subcultured up to 20 times without changes in cell viability, proliferation rate, or morphology. Furthermore, SI-PMEC cells remained

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.
腺病毒可以在293A细胞中进行转录，表达并可进行包装复制出大量高滴度病毒。293T是一种逆转录包装表达细胞，我做过也可进行表达，但还没有具体鉴定表达后的病毒是否可用。293细胞系是原代人胚肾细胞转染5型腺病毒（Ad 5）DNA的永生化细胞，表达转染的腺病毒5的基因。细胞来源都是人肧肾上皮细胞，293T细胞表达E1A蛋白，SV40大T抗原，含有SV40复制起始点与启动子区的质粒可以复制。293FT细胞能制造高滴度的慢病毒。293A细胞来源于人肾纤维母细胞，组成性表达E1A 和E1B 蛋白
细胞名称 293 和 293T种属人组织来源 293细胞是转染腺病毒E1A基因的人肾上皮细胞系，293T细胞由293细胞派生，同时表达SV40大T抗原，含有SV40复制起始点与启动子区的质粒可以复制。用磷酸钙转染效率可高达50%。蛋白表达水平高，转染后2-3天用碱性磷酸酶分析可较容易地检测到表达的蛋白。瞬时转染293T细胞是过表达蛋白并获得细胞内及细胞外（分泌的或膜的）蛋白的便捷方式。形态特点 上皮细胞致瘤性 +产物或抗原 大T抗原染色体核型 亚三倍体人细胞系。染色体众数为64，30%的细胞
足细胞来源： 丁香园网友yulinlong的观点为： 很多细胞中心就有卖的，或者有的公司可以代理ATCC公司的就可以。 有的文献用的永生化细胞系是他们自己建的系或者别人建系赠予的，你也可以考虑向国内或者国外去请求馈赠。有的会给的。 丁香园网友wenyueqiang的观点为： 美国爱因斯坦大学的PETER MUNDEL有 足细胞
