FN1 and acute lymphoblastic leukemia: We investigated whether DEX treatment could potentiate EMT in NALM6 cells that were co-cultured with MSCs by enriching Adh ALL cells with EMT phenotype by treating the cells with either vehicle or 50 nM DEX (the IC75 of DEX in NALM6 mono-culture) and found that DEX treatment slightly increased EMT, as evidenced by the increased fibronectin expression in DEX-treated NALM6 with MSCs (Figure S5D).
