Embodiment 1
[0038] The patient, female, 33 years old, the liver tumor tissue was fully washed with normal saline, and the normal tissue and necrotic area around the liver cancer specimen were removed. If overnight reprocessing is required, the liver cancer specimen should be transferred to a 50ml centrifuge tube containing about 10ml of complete medium and stored at 4°C. Put the liver cancer specimen in a sterile glass culture dish (Petri dish), add a small amount of normal saline, and use surgical scissors to cut out a size of about 1-2mm from different areas around the specimen 3 The number of small tissue blocks is generally not less than 8. Take a small piece of liver cancer tissue cut out and place it in one well of a 24-well plate, each well containing 2ml of complete medium and 6000 (or 3000) IU / ml of IL-2, and operate the other wells in the same way. Place the 24-well plate at 37°C, 5% CO 2 cultured in a cell culture incubator. The proliferation of lymphocytes around the tissue...
