Colostrums and Milk-Derived Peptide Growth Factors
Epidermal growth factor (EGF) has been shown to have positive effects in a trinitrobenzenesulfonic acid/ethanol model of colitis. Colostrum, which contains certain cytokines such as platelet-derived growth factor, EGF, insulin-like growth factor, and transforming growth factor beta may therefore be beneficial in IBD.
IGF-1 has been shown to promote gastrointestinal healing. However, it is also a mitogen because it promotes cell growth, and because of the lack of large randomized controlled trials, caution should be exercised. Of note, however, in an oral dextran sulphate sodium-induced model of colitis, short-term administration of IGF-1 was shown to have beneficial healing effects. Another study showed that EGF enemas combined with oral mesalamine had a positive effect on ulcerative colitis disease activity.
