Figure 4. Hematoxylin and Eosin staining of tat-transgenic lungs.
Formalin-fixed paraffin-embedded lung sections from Tat transgenic and non-transgenic mice were stained and examined by light microscopy. A representative photomicrograph of each is shown. While the gross morphology and architecture of the lungs does not appear to be affected by the transgene, Tat transgenic mice exhibited more cellular infiltration than non-transgenic mice.
