[Abstract] Liver fibrosis results from the excessive collagen deposition (collagen scar) by activated hepatic stellate cells (HpSCs), leading to the inhibition of normal liver regeneration and function. Fibrogenesis is a complex mechanism involving both the synthesis and degradation of matrix proteins by different cell types, mainly macrophages in the liver. Carbon tetrachloride-induced fibrosis (CCl4) and cirrhosis is one of the oldest, simplest and probably the most widely used toxin-based experimental model for the induction of fibrosis. Here we have explained experimental animal model of liver fibrosis using CCl4, injecting twice a week for a period of 8 weeks. In these fibrotic mice, bone marrow (BM) derived CD45+ cells were transplanted via intrasplenic route ...

[Abstract] Immunofluorescent staining of organoids can be performed to visualize molecular markers of cell behavior. For example, cell proliferation marked by incorporation of nucleotide (EdU), or to observe markers of intestinal differentiation including paneth cells, goblet cells, or enterocytes (see Figure 1). In this protocol we detail a method to fix, permeabilize, stain and mount intestinal organoids for analysis by immunofluorescent confocal microscopy.

[摘要] 可以进行类器官的免疫荧光染色以显现细胞行为的分子标志物。例如，通过掺入核苷酸（EdU）标记的细胞增殖，或观察肠分化的标志物，包括paneth细胞，杯状细胞或肠细胞（参见图1）。在这个协议中，我们详细的方法来修复，透化，染色和安装肠组织，通过免疫荧光共聚焦显微镜分析。
