Embodiment 1
[0072] In this embodiment, the method for preparing a large amount of TIL cells with high killing activity by using clot-containing malignant pleural effusion includes the following steps:
[0073] (1) Collection of clot-containing malignant pleural effusion: under sterile conditions, collect 1000 mL of clot-containing malignant pleural effusion caused by lung cancer, and add 15,000 U of heparin;
[0074] (2) Separation of free cells and clots in malignant pleural effusion containing clots: use a nylon microporous filter with a pore size of 70 μm to filter the malignant pleural effusions containing clots to separate the clots and free cells in malignant pleural effusions Separated to obtain free cell-A;
[0075] (3) Decomposition of the clot and release of free cells: the clot was placed in AIM-V complete medium-I containing 750 U / mL IFN-γ, 55 U / mL IL-2 and 3% inactivated serum in 37°C, 5% CO 2 Cultivate for 3 days under the condition of saturated humidity and filter to obta...
Embodiment 2
[0083] In this embodiment, the method for preparing a large amount of TIL cells with high killing activity by using clot-containing malignant pleural effusion includes the following steps:
[0084] (1) Collection of clot-containing malignant ascites: under sterile conditions, collect 1200 mL of clot-containing malignant ascites caused by gastric cancer, and add 18,000 U of heparin;
[0085] (2) Separation of free cells and clots in malignant ascites containing clots: use a nylon microporous filter with a pore size of 70 μm to filter the malignant ascites containing clots to separate the clots and free cells in malignant ascites. Separated to obtain free cell-A;
[0086] (3) Decomposition of clot and release of free cells: place the clot in AIM-V complete medium-I containing 500 U / mL IFN-γ, 100 U / mL IL-2 and 3% inactivated serum At 37°C, 5% CO 2 Cultivate for 4 days under the condition of saturated humidity and filter to obtain free cell-B;
[0087] (4) Separation of mononuc...
Embodiment 3
[0094] In this embodiment, the method for preparing a large amount of TIL cells with high killing activity by using clot-containing malignant pleural effusion includes the following steps:
[0095] (1) Collection of clot-containing malignant pleural effusion: under sterile conditions, collect 1000 mL of clot-containing malignant pleural effusion caused by lung cancer, and add 15,000 U of heparin;
[0096] (2) Separation of free cells and clots in malignant pleural effusion containing clots: use a nylon microporous filter with a pore size of 70 μm to filter the malignant pleural effusions containing clots to separate the clots and free cells in malignant pleural effusions Separated to obtain free cell-A;
[0097] (3) Decomposition of clot and release of free cells: place the clot in AIM-V complete medium-I containing 500 U / mL IFN-γ, 100 U / mL IL-2 and 3% inactivated serum At 37°C, 5% CO 2 Cultivate for 5 days under the condition of saturated humidity and filter to obtain free ...
