Table 1 Characterization of the peripheral blood mononuclear cells (PBMC)

	T-lymphocytes (%)		B-lymphocytes (%)		NK cells (%)
	Median	Range	Median	Range	Median	Range
Peripheral blood mononuclear cells (PBMC)	71.2	6.2	7.2	2.4	8.3	1.7
PBMC + MCF-7 culture medium	68.4	12.7	5.5	2.2	5.3	0.9
PBMC + co-culture medium	71.6	8.1	8.1	1.5	5.3	3.6

Co-culture = lymphocytes from a healthy woman in the presence of MCF-7 cells for 18 h
PBMC was incubated with culture medium of MCF-7 cells and co-culture for 4 h at 37 °C and 5% CO₂
