The stimulation of immune response by intratumoral injection of λ-carrageenan in mice.
(A) Infiltrated macrophages (left) and dendritic cells (right) in B16-F10 tumor tissues after λ-carrageenan treatment were analyzed by flow cytometry. Total numbers of 20000 cells were analyzed. M1 and M2 macrophages were illustrated and the numbers indicate the percentage of the cells in total cells. (B) Splenic lymphocytes were analyzed by flow cytometry after λ-carrageenan treatment. Total numbers of 20000 cells were collected. Numbers illustrated indicate the percentage of the cells in total cells. NS is for normal saline group as control. Independent experiments were repeated three times with similar results.
