Among in vivo angiogenesis assays, chick chorioallantoic membrane (CAM) assay has allowed meaningful progress in elucidating the mechanism of the vasoproliferative response to several pro- and antiangiogenic factors, thanks to its low costs, relatively easy management, and lower ethical concerns compared to other animal in vivo models.Here, we present a method to quantify angiogenesis and antiangiogenesis processes in the CAM based on the segmentation of microscopic images of blood vessels. Images captured from in vivo CAM samples can be analyzed for their vascularization with IKOSA CAM Assay to measure their total area, length, mean thickness, and the number of branching points. This chapter presents a detailed protocol to perform a CAM assay and analysis, and the IKOSA CAM Assay output is described.
在体内血管生成分析中,鸡胚绒毛尿囊膜(CAM)分析由于其成本低、管理相对简单以及与其他体内动物模型相比伦理问题较少,使得在阐明血管生成反应的机制方面取得了有意义的进展。在此,我们提出了一种基于血管分割的方法,来量化 CAM 中的血管生成和抗血管生成过程。通过对体内 CAM 样本的显微图像进行分析,可以使用 IKOSA CAM 分析来测量其总面积、长度、平均厚度和分支点数量。本章介绍了一种详细的 CAM 分析方案,并描述了 IKOSA CAM 分析的输出结果。
