Induction of Egr-1 mRNA after intraperitoneal injections of VEGF and EGF.
Mice received intraperitoneal injections of VEGF, EGF, or normal saline. Tissues were processed 1 hour later for Northern blot analysis of Egr-1 and 18S ribosome in the heart (H), lung (Lu), brain (B), kidney (K), liver (Li), spleen (Sp), and skeletal muscle (Sk). +, growth factor-treated mice; −, normal saline-treated mice.
