Effect of insulin on PAI-1 mRNA in the adipose tissue of lean mice
In situ hybridization was performed on paraffin sections of epididymal fat pad from untreated mice (A) and mice treated with insulin (B-D). Slides were exposed for 8 weeks at 4°C and stained with hematoxylin and eosin. e, endothelial cell; arrowheads, positive signal for PAI-1 mRNA. Magnification: 400× for all sections.
