Imminostaining patterns of AMPK-, ACC-, FAS-, and SREBP-1-positive cells. Brain sections from P7 and P19 were stained with anti-AMPK, anti-ACC, anti-FAS, and anti-SREBP-1 antibodies using the ABC method. For controls, the antibodies were incubated with blocking peptides for 1 h at room temperature before applying to P7 brain sections. For other experiments, the antibodies were incubated without blocking peptides for 1 h at room temperature before applying to P7 or P19 brain sections. Representative images show the cingulate cortex regions. Arrows show some of the cells morphologically similar to oligodendrocytes/oligodendrocite progenitors. The scale bar indicates 25 µm.
