小鼠结肠上皮细胞系简介：
产品描述：小鼠结肠分升结肠、横结肠、降结肠和乙状结肠4部分，大部分固定于腹后壁，结肠的排列酷似英文字母“M”，将结肠包围在内。结肠横切面由内到外依次为：黏膜（上皮层、固有层、黏膜肌层），黏膜下层（疏松结缔组织），肌层（内环形、外纵行两层平滑肌），外膜（纤维膜或浆膜）。肠黏膜上皮细胞是机体内外环境的重要屏障，持续暴露于大量抗原中，也是机体面对病原微生物的第一道防线。因此，肠黏膜上皮细胞除有吸收、分泌和转运等重要生理功能之外，在黏膜先天性和获得性免疫防御机制中也起着重要作用。肠黏膜上皮细胞作为首先接触抗原的细胞，在黏膜免疫反应的起始阶段发挥关键作用，它决定黏膜免疫反应的发生、性质和强度。探讨正常结肠黏膜上皮细胞的分离、体外培养方法，为研究肠黏膜上皮细胞以及与肠黏膜相关疾病建立合适的细胞模型。

Development of a primary mouse intestinal epithelial cell monolayer culture system to evaluate factors that modulate IgA transcytosis
There is significant interest in the use of primary intestinal epithelial cells in monolayer culture to model intestinal biology. However, it has proven to be challenging to create functional, differentiated monolayers using current culture methods, likely due to the difficulty in expanding these cells. Here, we adapted our recently developed method for the culture of intestinal epithelial spheroids to establish primary epithelial cell monolayers from the colon of multiple genetic mouse strains. These monolayers contained differentiated epithelial cells that displayed robust transepithelial electrical resistance. We then functionally tested them by examining IgA transcytosis across Transwells. IgA transcytosis required induction of polymeric immunoglobulin receptor (pIgR) expression, which could be stimulated by a combination of LPS and inhibition of γ-secretase. In agreement with previous studies using immortalized cell lines, we found that TNFα, IL-1β, IL-17 and heat-killed microbes also stimulated pIgR expression and IgA transcytosis. We used wild-type and knockout cells to establish that amongst these

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.
Immunity：「填补教科书」董晨院士团队解析 IL-17D 重要功能，并首次发现其受体
分泌的呢？作者通过分离小鼠结肠组织中的 CD45 + 和 CD45 - 细胞来探索 IL-17D 细胞来源，结果发现 CD45 - 细胞（以结肠上皮细胞为主）高表达 Il17d mRNA，提示结肠上皮细胞可能是 IL-17D 的主要来源。这一结果也通过免疫荧光染色和骨髓嵌合体小鼠模型得到了进一步的证实。 图片来源：Immunity「我要到哪里去」IL-17D 作用于什么细胞而发挥功能？进一步地，作者研究了 IL-17D 作用的靶细胞。IL-22 及其下游效应蛋白，如 RegIIIb 和 RegIIIg
