Abstract

The invention discloses a method for culturing a kidney cancer organ. The method comprises the following steps: placing small kidney cancer tissue blocks in an inhibitor containing type II collagenase, and carrying out first digestion treatment to obtain a first digested substance; placing the first digested substance in a pancreatin substitute containing an inhibitor, and carrying out second digestion treatment to obtain a second digested substance; sequentially carrying out first neutralization treatment, filtering treatment and centrifugal treatment on the second digested substance to obtain single-cell precipitate; placing the single-cell precipitate in a mixed substrate of a preset culture medium and substrate glue for resuspension treatment to obtain a gel suspension containing all cells; and culturing the gel suspension according to a preset scheme, thereby obtaining the kidney cancer organ. According to the scheme, the accuracy of an expected treatment result can be improved.

Description

technical field [0001] The present application relates to the technical field of organoid culture, in particular to a method for culturing kidney cancer organoids. Background technique [0002] Renal carcinoma is a malignant tumor originating from the urinary tubular epithelial system of the renal parenchyma, and is one of the most common urinary system tumors. According to the different pathological types, renal cancer mainly includes three subtypes: clear cell renal cell carcinoma (ccRCC), papillary renal cell carcinoma (pRCC) and chromophobe renal cell carcinoma (renal cell carcinoma). carcinoma, crRCC). Kidney cancer is estimated to affect 300,000 people worldwide and kill more than 100,000 annually, with a steady increase in new cases in many countries and regions, including the United States and Europe. [0003] The clinical treatment of RCC varies with tumor stage and pathological type. Nephron-sparing surgery or radical nephrectomy can be used for patients with ea...
