Effect of intradermal TNFα on VCAM-1 expression in rat skin microvasculature. Tyrode or TNFα (10−11 mol/site) was ID injected into the back skin of the animal. Photomicrographs show VCAM-1 expression (red staining) in Tyrode-injected (A) or TNFα-injected sites (B) after a 4-hour in vivo test period. Original magnification × 200.
