Figure 1. Endogenous PRL levels are regulated by hindpaw incision in intact female and male rats.

Figure 1

(A) Endogenous PRL levels in serum of male and female rats. Data were acquired 24 h after incision of hind paws (*p<0.05; **p<0.01; unpaired t-test; n=4). (B) Endogenous PRL levels in ipsi-lateral hind paw biopsies of male and female rats. Data were acquired 24 h after incision of hind paws (**p<0.01; ***p<0.001; unpaired t-test; n=4). (C) Endogenous PRL levels in contra-lateral hind paw biopsies of male and female rats. Data were acquired 24 h after incision of ipsi-lateral hind paws (NS – non-significant; unpaired t-test; n=4). (D) Endogenous PRL levels in L4-L6 level lumbar spinal cord of male and female rats. Data were acquired 24 h after incision of hind paws (NS – non-significant; ***p<0.001; unpaired t-test; n=4).
