Fig. 3From: Intratumoral regulatory T cells from colon cancer patients comprise several activated effector populationsFrequencies of intratumoral Treg and CD39+ Treg in relation to tumor microsatellite status. Frequencies of CD39+ Treg were determined by flow cytometry in cell suspensions isolated from colon tumors. A Frequencies of Treg among intratumoral CD4+ cells in MSS tumors and MSI-H tumors (n = 44). B Frequencies of CD39+ Treg among intratumoral Treg in MSS tumor and MSI-H tumors of patients belonging to group I and II (n = 44). Symbols represent individual values and horizontal lines the median. Individual values are color-coded in red (group I) and blue (group II)Back to article page
