الوصف: Background The olfactory bulb has a key role for nasal delivery of drugs to the brain by its access from the nasal mucosa and its connection to the subventricular zone. The aim of this study was to investigate the neuromodulatory capacity of human milk of premature infants on the olfactory bulb. Methods Olfactory bulbs from P1 mice were embedded in a collagen I gel and incubated with DMEM supplemented with the aqueous phase of human colostrum (Col) of five mothers after very preterm birth, mature milk (Mat) of the same mothers or without supplement (Ctrl). After 7 days, the neurite outgrowth was quantified. Proteome analysis of the milk samples was performed using unlabeled mass spectrometry. Results Outgrowth increased significantly in bulbs exposed to Col but not when exposed to Mat. Mass spectrometry revealed profound differences in the proteome of Col versus Mat. Among 21 upregulated proteins in Col were proteins involved in neurite outgrowth, axon guidance, neuromodulation and longevity. Conclusions A high bioactivity of human preterm colostrum on murine neonatal neurogenic tissue is demonstrated to be associated with a proteome profoundly differing from mature milk. Impact The hypothesis has been raised that neonatal brain damage in a preterm infant could potentially be ameliorated by intranasal application of maternal breast milk. In an in-vitro model using neonatal murine olfactory bulb explants a significant stimulatory effect by human preterm colostrum is observed. Proteomics reveals upregulated neuroactive proteins in human colostrum compared to mature milk. A confirmation of this exploratory study would indicate that preterm colostrum stimulates neurogenic tissue. Early intranasal colostrum application might attenuate perinatal loss of neurogenic tissue thereby contributing to reducing complications such as cerebral palsy.
