Fig. 5From: All-trans retinoic acid arrests cell cycle in leukemic bone marrow stromal cells by increasing intercellular communication through connexin 43-mediated gap junctionEffects of ATRA on the cell viability of BMSCs (MTT assay). Cell viability was evaluated by MTT assay in leukemic BMSCs, leukemic BMSCs treated with ATRA, and leukemic BMSCs treated with both ATRA and amphotericin-B. Data are presented as mean ± SD. Single asterisk indicates significant difference (P < 0.05)Back to article page
