Induction culture method of cancer cytotoxic T lymphocytes

摘要

A process for an induction culture of a cytotoxic T lymphocyte having cell killing activities against a tumor cell which comprises the step of coculturing a tumor tissue containing said tumor cell and a lymphocyte of autologous peripheral blood obtained from a subject from which the tumor tissue is derived. The process is convenient since no separation and pure culture of tumor cells is required. The resulting cytotoxic T lymphocyte cells are useful for clinical treatments of tumors, e.g. adoptive immunotherapies.
