MODIFIED RAPID EXPANSION METHODS ('MODIFIED-REM') FOR IN VITRO PROPAGATION OF T LYMPHOCYTES

摘要

The present invention provides a modified rapid expansion method (termed 'low-PBMC-REM' or 'modified-REM'), for quickly generating large numbers of T lymphocytes, including cytolytic and helper T lymphocytes, without using the large excesses of peripheral blood mononuclear cells (PBMC) or EBV-transformed lymphoblastoid cells (LCL) characteristic of high-PBMC-REM. Clonal expansions of greater than 500-fold can be achieved within a single stimulation cycle of about 8-14 days.
