SREBF1 and acute lymphoblastic leukemia: To investigate the effect of inhibiting SREBF1 in induced BMSC on the support of T‐ALL cells, we induced BMSC treated with or without an SREBF1 inhibitor (Fatostatin HBr, FH) in DEX adipogenic medium for 21 d, and T‐ALL cells were added to the two kinds of BMSC‐derived ADs.
