Bone marrow-derived mesenchymal stromal cells preactivated with mast cells regulate allergy-related genes in CD34+ progenitors. BM-MSCs were exposed to non-activated or activated mast cells in a Transwell system and freshly isolated CD34+ cells were added to the cultures for 10 h. Early genes for effector differentiation were analyzed in CD34+ cells following culture with BM-MSCs by real-time PCR. Mean ± SEM of four experiments.
