Overview

Randomized trial evaluates NK cell activation and expansion in leukopak mononuclear cells, indicating effective therapeutic application.

Key Points

  • Evaluate GMP reagents for NK cell isolation, activation, and expansion to enhance adoptive cell therapy.
  • NK cells isolated from leukopak mononuclear cells via positive and negative selection methods.
  • NK cells activated and expanded for 14 days in vitro using GMP-grade recombinant human IL-2 and IL-15.
  • Both isolation methods produced highly viable NK cell populations with varying purity.
  • Functional analyses indicated effective cytokine secretion post-expansion with strong target cell killing capacity.
