The patient's HCC tissue, obtained by intraoperative resection or needle biopsy, is enzymatically or mechanically broken down to obtain dispersed tumour cells. The tumour cells are cultured in dishes to obtain the HCC organoids. Normal hepatocytes from other sources are cultured in dishes to obtain normal liver organoids. The CRISPR/Cas9 system can be used to induce the generation of HCC organoids. The nutrient solution used for culture was adjusted according to the growth characteristics of HCC.
