The Regenerative Potential of Donkey and Human Milk on the Redox-Sensitive and Proliferative Signaling Pathways of Skin Fibroblasts

Figure 5

p-STAT-1 kinase and CD26 signaling of skin fibroblast cultures exposed to different milk samples, β-casein, and β-casomorphine-7. Fibroblasts exposed to the following milk species: donkey colostrum (donkey 1); donkey mature milk (donkey 2); human colostrum (human 1); human mature milk (human 2); casein 1/10 (cas I); casein 1/100, (cas II); beta-casomorphine-7, 1/10, (CSM I); beta-casomorphine-7, 1/100 (CSM II); and control group. Each group comprised of 4-6 culture samples.
