永生化脐动脉平滑肌细胞简介:
产品描述:脐带是胎儿和胎盘之间的连系结构。形状如绳索,表面光滑透明,内含结缔组织和一支脐静脉,一对脐动脉。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。

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.
构建组织工程血管有两种:①用正常动脉壁细胞与细胞外基质重建血管;②用正常血管壁细胞、细胞外基质和可降解材料构建血管。 血管壁中切取弹性基膜,并在其上培养鼠动脉平滑肌细胞;或用工型胶原制备基质材料与各型血管壁细胞成分合成血管模型。首先将平滑肌细胞与成纤维细胞分别培养形成细胞层,将成纤细胞层脱水去细胞形成内膜(IM),再将内膜绕在中轴上,外裹平滑肌细胞和成纤细胞层,经过体外8周长时间成熟后,内壁注入内皮细胞使之内皮化。各项检测及动物实验,结果从机械强度、血液相容性、可缝合
-1)的脱氧核酶来抑制NI形成的鼠模型中Egr-1的表达,结果NI的形成亦受到抑制,表明Egr-1在动脉结扎后动脉内膜增厚中具有重要意义。由于c-Jun在正常动脉壁中很少表达,而在损伤动脉中短暂升高,Khachigian[16]等设计了针对c-Jun的脱氧核酶(Dz13),该酶能抑制血管平滑肌中c-Jun的表达,抑制血管平滑肌细胞的增殖,在体外能阻止损伤的平滑肌细胞的修复,在体内能抑制鼠颈动脉内膜的增厚,表明c-Jun能影响NI的形成,进而在血管性疾病中具有重要的作用。 Twist为一螺旋-环-螺旋
。在缺氧性肺血管收缩反应中,组胺释放增多,主要作用于H2受体以限制肺血管的收缩。③缺氧直接对血管平滑肌作用:缺氧使平滑肌细胞膜对Na+、Ca2+的通透性增高,促使Na+、Ca2+的通透性增高,促使Na+、Ca2+内流,导致肌细胞兴奋性与收缩性增高。这一观点还有待进一步证实。看来缺氧性肺血管收缩反应是多因素综合作用的结果。 4、毛细血管增生长期慢性缺氧可促使毛细血管增生。尤其是脑、心脏和骨骼肌的毛细血管增生更显著。毛细血管的密度增加可缩短血氧弥散至细胞的距离,增加对细胞的供氧量。
