Human adipose tissue-derived mesenchymal stem cells (hADSCs) have power to differentiate various cell types including chondrocytes, osteocytes, adipocytes, neuron, cardiomyocytes, and smooth muscle. In the present study, we characterize the functional expression of ion channels using TGF-β1-induced differentiation of hADSCs and provide the clues for differentiation to the vascular smooth muscle cells. The treatment of TGF-β1 to the hADSCs dramatically increased the expression levels of smooth muscle specific genes including α-smooth muscle actin (α-SMA), calponin, SM-MHC, smoothelin-B, myocardin, and h-caldesmon with contraction of collagen gel lattice. TGF- β1-induced differentiation of hADSCs appeared the Ca2+, big-conductance Ca2+- activated K+ (BKCa), and voltage-dependent K+ (Kv) currents comparing lack of these current in undifferentiated hADSCs. These appearing currents shared the characteristics of vascular smooth muscle cells (SMCs). RT-PCR and western blotting revealed that L-type (Cav1.2) and T-type (Cav3.1, 3.2, 3.3) Ca2+ channels, which have known to express vascular SMCs, were dramatically increased in TGF-β1-induced differentiation of hADSCs with Cav β1 and Cav β3 subtypes. Although the expression changes in β-subtypes of BKCa channel were relatively various, the major α-subtypes of BKCa channel (KCa1.1) were increased in TGF-β 1-induced differentiation of hADSCs. The most Kv subtypes, which known to express in vascular SMCs, also dramatically increased in TGF-β1-induced differentiation of hADSCs. These results suggested that TGF-β1 induced differentiation of hADSCs into the contractile vascular SMCs with expression of vascular SMCs-like ion channels.
