<p><b>A</b> Example of 3T3-L1 adipocytes in the fibroblast-like state before differentiation (left) as well as when differentiated into mature adipocytes (right). <b>B</b> Representative capacitance recording with Δ<i>C</i><sub>m</sub> (delta membrane capacitance) plotted against time showing how analyses were carried out. Δ<i>C</i>/Δ<i>t</i> was measured at the time intervals indicated by the dotted lines by fitting straight functions to the data points (red lines superimposed on the black capacitance trace). Scale bar = 50μm.</p
