Improved Activation toward Primary Colorectal Cancer Cells by Antigen-Specific Targeting Autologous Cytokine-Induced Killer Cells

Table 1

Characterization of CIK cells.

Marker	Positive cells (%)
CD3	98.6
CD4	22.1
CD8	67.8
CD14	0.0
CD33	9.3
CD56	31.7
HLA-DR	67.4

CIK cells were generated from peripheral blood lymphocytes from a healthy donor as described in Section 2. After 2-3 weeks of propagation, cells express the phenotype of CD3⁺CD56⁺ CIK cells. Data of a representative CIK cell induction are shown.
