永生化大鼠子宫平滑肌细胞
细胞简介：
虽然原代大鼠子宫平滑肌细胞更能真实地反映子宫平滑肌细胞在大鼠体内的生理状态，但是一方面原代分离培养大鼠子宫平滑肌细胞周期长及对技术人员经验要求非常高，另一方面此原代细胞在体外培养生长缓慢，不能多次传代，这些不利因素制约了原代大鼠子宫平滑肌细胞在实验室的广泛应用。欣润生物的研究团队拥有多年原代细胞分离培养及细胞永生化服务研究经验，成功建立了永生化大鼠子宫平滑肌细胞。
子宫是动物的雌性生殖器官的一部分，是动物胎儿或幼体发育生长的场所。子宫肌层比较厚，由成束或成片的平滑肌组成，肌束间以结缔组织分隔。子宫平滑肌具有收缩功能，收缩受激素的调节，其收缩活动有助于精子向输卵管运送、经血排出以及胎儿娩出。子宫平滑肌细胞的分裂增殖还受性腺激素的影响。
本公司生产的永生化大鼠子宫平滑肌细胞采用酶解法和基因转染制备而来，细胞总量约为1×106/T25方瓶，细胞纯度可达90%以上，且不含有HIV-1、 HBV、HCV、支原体、细菌、酵母和真菌等。

我们推荐使用欣润生物研制的永生化大鼠子宫平滑肌细胞完全培养基（产品编号：IR3004-5）作为体外培养永生化大鼠子宫平滑肌细胞的培养基。
Immortalization and characterization of human myometrial cells from term-pregnant patients using a telomerase expression vector
An examination of cellular processes involved in myometrial function has been greatly assisted by the use of human myometrial cells in primary culture. However, these cells can be used only for several passages before they senesce, and responses to various agents change with time in culture. The use of transformed cells is limited, as they can be polynucleated and can lose or gain chromosomes. We have developed three telomerase-immortalized cell lines from term-pregnant human myometrium to eliminate variability between passage numbers and allow genetic manipulations of myometrial cells to fully characterize signal pathways. These cells have a normal karyotype and were verified to be uterine smooth muscle by immunocytochemical staining for smooth muscle cell-specific alpha-actin and high affinity oxytocin antagonist binding sites. The three cell lines and the cells in primary culture from which they were derived were examined by cDNA microarray analysis. Of >10 000 expressed genes, there were consistent changes in the expression of approximately 1% in the

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.
