The isolation of an immortalized and tumorigenic cell line from p21WAF1 null mouse bladders
Given a role for the deregulation of p21WAF1 in the progression of bladder tumors, we examined the growth of cultured urothelial cells from wild-type and p21WAF1 null bladders. Bladders were excised, minced from euthanized p21WAF1 and wild-type mice, treated overnight with dispase, and then placed into flasks coated with collagen type I in Dulbecco modified Eagle medium with 10% fetal calf serum. After an overnight incubation, the media was replaced with a serum-free media and a portion of explants were treated with 12-O-tetrade-canoylphorbol-13-acetate (TPA) on day 7 and continued for either 4 or 9 wk. The urothelial origin of any surviving epithelial cells was determined by reverse transcription-polymerase chain reaction (RT-PCR) using uroplakin II-specific primers, and the expression of the cell cycle-related proteins, p161NK4 and p19ARF, was examined by semiquantitative RT-PCR and Western blotting. Isolated wild-type and serially passaged p21WAF1 null epithelial-like cells were then injected subcutaneously into nude mice. We found that phorbol

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.
为同一类型的细胞，如上皮细胞或成纤维细胞，也仍具有异质性，在分析细胞生物学特性时比较困难。其次，由于供体的个体差异及其他一些原因，细胞群生长效果有时也不一致。原代培养也是建立各种细胞系（株）必经的阶段。假如原代培养能够维持几小时甚至更长，即可进行进一步筛选。有的细胞具有继续增殖能力，有的细胞类型只是存活而不增殖，而另外一些细胞只是在特殊条件下应用而不存活，因而细胞类型的分布将会改变。在单层培养的情况下，瓶底全部铺满细胞，达到会合以后，对密度有依赖性的细胞则逐渐减少生长，而失去密度依赖敏感性的细胞
基质上培养 (贴壁或者单层培养)，而另一些细胞则可在培养基中漂浮生长 (悬浮培养)。冻存如果传代时有多余的细胞，可通过适当的保护剂 (例如：DMSO 或甘油) 处理细胞，储存在 –130°C 以下的温度下 (冻存)，直到需要使用之时。 培养细胞的形态 根据形状和外观 (即：形态) 可将培养的细胞分为三大类。 • 成纤维细胞 (或者成纤维细胞样细胞) 为双极或多极细胞，呈细长形，贴附在基质上 生长。 • 上皮样细胞呈多角形，尺寸更为规则，贴附在基质上呈散在斑
