Here, we present a protocol for quantifying xenografted human glioblastoma stem cells (GSCs) in zebrafish larvae. We first describe steps for orthotopic xenotransplantation of GSCs into the midbrain of zebrafish larvae, immunofluorescent labeling, and confocal imaging. We then detail procedures for GSC quantification using the Cellpose algorithm. This protocol provides a technique for the semi-automatic segmentation and quantification of human cancer cells in xenograft experiments. With this approach, cancer cell survival and proliferation can be determined in an unbiased manner.
在此,我们展示了一种用于定量斑马鱼幼虫中异种移植的人胶质母细胞瘤干细胞(GSCs)的方案。我们首先描述将GSCs原位异种移植到斑马鱼幼虫中脑、免疫荧光标记和共聚焦成像的步骤。然后,我们详细介绍使用Cellpose算法进行GSC定量的程序。该方案提供了一种在异种移植实验中对人癌细胞进行半自动分割和定量的技术。通过这种方法,可以以无偏倚的方式确定癌细胞的存活和增殖情况。
