Human breast milk is the best nutrition for human babies ensuring all their nutritional needs for healthy development. However, as much as half of the newborns worldwide are not properly breastfed due to multiple reasons, including maternal lactation insufficiencies, infections etc. Current commercial human milk replacements do not reach the full quality of human breast milk and the milk biobanks do not meet the high demands. Therefore, there is an unmet need for full-quality human breast milk. This project aims to further develop our unique biotechnology for milk production in the laboratory towards production of human breast milk.
