Effect of insulin on the cellular distribution of TF mRNA in the lungs of lean mice.

In situ hybridization was performed on paraffin sections from the lungs of untreated (A) and insulin-treated (Himulin, 10 U; 6 hours) (B) lean (C57BL/6J) mice. Slides were exposed for 4 weeks at 4°C and stained with hematoxylin and eosin. Arrowheads indicate positive cells. Original magnification is × 400 for both sections.
