产品介绍
细胞名称：大鼠主动脉平滑肌细胞系、永生化大鼠主动脉平滑肌细胞
背景描述：平滑肌细胞对心血管疾病的发生起着极其重要的作用。心血管疾病的发生和发展的一个主要因素在于心血管平滑肌细胞转变成为了具有增殖能力的表型。近期的研究表明，平滑肌细胞能表达钙离子通道ICAM-1和VCAM-1，其中ICAM-1和VCAM-1的表达可能是造成血管壁炎症反应，并进一步造成心血管疾病的原因。因此，对血管平滑肌细胞的体外培养和研究可用来发现和确定新的血管疾病的靶向治疗方法。

Leptin stimulates rat aortic smooth muscle cell proliferation and migration.
Leptin, a peptide secreted from adipose tissue, plays an important role in the regulation of food intake and energy expenditure. In obese patients, plasma leptin levels are elevated and obesity is one of the major risk factors for cardiovascular diseases. Therefore, in this study, we investigated the effect of leptin on vascular smooth muscle cell (VSMC) functions. Cultured rat aortic VSMC expressed 130-kDa short form of leptin receptor. Leptin stimulated both proliferation and migration of VSMC. Leptin stimulated phosphorylation and activation of mitogen-activated protein (MAP) kinases, and also increased phosphatidylinositol (PI) 3-kinase activity. Further, two distinct PI 3-kinase inhibitors, wortmannin and LY294002 inhibited the migratory effect of leptin. These results demonstrate that leptin is a proliferative and migratory factor for VSMC, implying that leptin may play a role in the formation and development of vascular lesions.

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.
，平滑肌细胞胞质呈现较强棕红色荧光。 六、注意事项 1、为了保持细胞活力，大鼠适宜采用药物麻醉后取材。大鼠应严格消毒，无菌解剖，打开胸腔后换取另一套器械获取主动脉血管。 2、注意尽可能洗涤净血管内的残血，避免血细胞及某些血清成分对细胞贴壁的影响。 3、血管由内膜层，中膜层和外膜层三层膜结构构成，而血管平滑肌细胞主要分布在血管中膜层，采用机械刮除法去掉内膜后再获取中膜以分离细胞，从血管内膜面刮下的细胞可以收集计数，培养主动脉血管内皮细胞。 4、酶消化法分离血管平滑肌细胞，酶消化过度容易损伤细胞，影响
