一般說明
血管生成是新生毛细血管生成的过程。 它是许多正常(生殖和伤口愈合)和病理过程(糖尿病性视网膜病,类风湿关节炎,肿瘤生长和转移)的基本组成部分1。
CHEMICON纤维蛋白凝胶体外血管生成测定试剂盒为评估96孔或其他形式的内皮细胞形成管提供了方便的系统。 当在纤维蛋白凝胶顶部或内部培养时,内皮细胞会迅速排列并形成可显示专利腔2,3的互连网络。 管的形成是一个涉及细胞粘连、迁移、分化和生长的多步骤过程4。 纤维蛋白凝胶中内皮细胞网络内细胞间连接和腔的形成取决于VE-钙粘蛋白,avb3和a5b1整联蛋白,cdc42和Rac1 GTPases以及膜型基质金属蛋白酶(MT-MMPs)的作用2,3,5,6。 体外纤维蛋白凝胶内的血管生成被认为是伤口愈合和肿瘤血管生成的准确模型,因为肿瘤细胞衍生的血管内皮生长因子/血管通透性因子可促进纤维蛋白原从肿瘤脉管系统渗漏并形成富含纤维蛋白的促血管生成临时基质7。
纤维蛋白凝胶的形成是通过凝血酶8对纤维蛋白原(一种异源三聚体)的酶促裂解而引发的。 所得裂解的纤维蛋白分子形成高度半透明的规则的多分子阵列。 该试剂盒中纤维蛋白原和凝血酶的浓度和配方经过优化,可通过HUVEC最大程度地形成试管,并易于观察这些试管。
應用
CHEMICON纤维蛋白凝胶体外血管生成测定试剂盒是一种简单的血管生成模型,可以轻松监测外源信号对管形成的诱导或抑制作用。 通过将纤维蛋白原和凝血酶溶液混合,可以轻松,快速地在培养皿中形成纤维蛋白凝胶。 对于测定管形成的抑制剂或刺激物,在将细胞添加到纤维蛋白凝胶顶部之前,简单地将内皮细胞混悬液与不同浓度的待测抑制剂或刺激物预混合。 在接种细胞后的第二天添加第二层纤维蛋白凝胶是可选的,但将促进最佳存活以及更高程度的网络和管腔形成。 该测定法可用于监测各种内皮细胞(例如人脐静脉细胞(HUVEC)或牛毛细血管内皮细胞(BCE))中管组装的程度。

"The successful, reliable culture of epithelial cells is critical for many areas of research, including dermatology, respiratory research, and cancer research. Because the breakdown of control mechanisms in epithelial cells is a frequent contributor to cancer progression and metastasis, epithelial cell culture is particularly important for cancer research. EpiGRO™ media formulations are optimized to provide better viability, proliferation rates, morphology and culture stability than other commercially available options. The media are provided in unique, light-blocking, temperature-monitored packaging to ensure stability and protect the media from damage by light, contamination, and excessive heat. The media do not require or contain any antimicrobials or phenol red. These components can cause cell stress and influence experimental results by masking the true performance or health of the cell culture. Phenol red acts like an estrogen and may stimulate growth independently of experimental variables. "
Key Steps in Tumor Metastasis
"Recognizing both the tremendous opportunities and the challenges facing cancer research, we are dedicated to developing and refining tools and technologies for the study of cancer. With our comprehensive portfolio, including the Upstate®, Chemicon®, and Calbiochem® brands of reagents and antibodies, researchers can count on dependable, high quality solutions for analyzing all the hallmarks of cancer."
