Embodiment Construction
[0025] see figure 1 , figure 1 The process flow diagram for the preparation of liver fibrosis organoids provided by the present invention.
[0026] Step 1: primary sorting of hepatic stellate cells and hepatic sinusoidal endothelial cells by flow cytometry, and cryopreservation in liquid nitrogen; or directly purchase frozen hepatic stellate cells and hepatic sinusoidal endothelial cells. Liver cancer cell lines were routinely cultured in advance (DMEM high-glucose medium supplemented with 1% penicillin / streptomycin, 10% fetal bovine serum; cultured in 25cm 2 Cell culture flasks, placed in a 37°C carbon dioxide incubator). When the confluence is about 80%, the liver cancer cell line is digested with trypsin, centrifuged at 800rps, and resuspended in medium A for counting. At the same time, hepatic stellate cells and hepatic sinusoidal endothelial cells were carefully recovered using an automatic cell recovery system, centrifuged at 800rps, resuspended in medium A, and count...
