In this video, we demonstrate a flow cytometry-based technique to determine the proportion of cytokine-induced killer T-cells, CIK cells, expanded from a peripheral blood mononuclear cell culture.

Protocol

All procedures involving human participants have been performed in compliance with the institutional, national, and international guidelines for human welfare and have been reviewed by the local institutional review board. 1. CIK induction and expansion On Day 0, culture the PBMCs (1 x 106) in fresh basal medium containing 1,000 IU/mL of IFN-γ for 24 h in a humidified cell culture incubator at 37 °C and 5% CO2. On Day 1, re…

Representative Results

Figure 1: The proportion of CD3+CD56+ T cells from a representative PBMC sample. (A) Lymphocytes were recognized by specific size and granularity. Selected single cell population for analysis by flow cytometry. (B) Statistical analysis of CIK expansion efficacy from three healthy donors was conducted using a t-test (*, p < 0.01).
