Figure 6: The Vd of lipid in FS and other cells in pars distalis was significantly increased. (a): morphometric data from the same animals and tissue sections used in Figure 4 showed a significant increase in the Vd of lipid droplets in Nhe2-/- mice when age groups were combined (* ), but was particularly striking in older Nhe2-/- mice. (b) and (c) are light micrographs, for which the bar is 20 μm; (d) is an electron micrograph, bar: 1 μm. Black arrows point to lipid droplets; C: canalicular space; N: nucleus.
