Web8 sep. 2014 · Despite the identification of an inwardly rectifying K + channel in osteoblasts and osteoclasts (24, 25), little is known about the contribution of these ion channels to bone morphogenesis. In the present study, we describe the presence of Kir2.1 channel currents in human osteoblasts and explore their role in osteoblastogenesis. WebThe inwardly rectifying nature of the currents was unaltered after removal of intracellular Mg 2+ and chelation with ATP and ethylenediaminetetraacetic acid (EDTA). Permeability ratios for other monovalent cations relative to K + were: K + (1.0)>Rb + (0.86)>Cs + (0.12)>Li + (0.08)>Na + (0.03).
