PARENTS who can’t or choose not to breastfeed should have a superior-to-formula option in just a few years, scientists say. The product, Biomilq, is the world’s first lab-grown breast milk. It’s founders say they’ve proven Biomilq’s nutrition profile matches the hundreds of proteins, complex carbs, fatty acids and other lipids “abundantly present” in breast milk as closely as possible. The company says Biomilq is more than just a collection of the components of breast milk. “Our core hypothesis has always been that milk is greater than the sum of its parts, which all work together as a dynamic system,” co-founder and chief science officer Leila Strickland said in a press release. “Our latest work demonstrates that much of the complexity of milk can be achieved by replicating the intricate relationship between the cells that produce it and the conditions they experience inside the body during lactation.” Strickland, a cell biologist, began growing mammary cells in a lab in 2013, but it wasn’t until 2019 that she partnered with food scientist Michelle Egger to launch the startup Biomilq. In February 2020, the pair announced their lab-grown mammary cells made the two key components of breast milk: lactose and casein — a pivotal step in creating a cultured breast milk that’s “nutritionally equivalent” to the real thing. Then, in June 2020, the pair announced they’d secured US$3.5 million from investors, including Breakthrough Energy Ventures, Bill Gates’ billion dollar fund focused on climate change. Egger said the team expects to launch the breast milk product in just over three years, once they’ve learned more about how the cells best thrive outside the body, checked all the safety boxes, and gained approval from regulators. Biomilq will look similar to milk, she said, and the team is strategizing how to reduce costs so the product won’t be significantly more expensive than formula. “We look forward to providing a product that overcomes financial, geographic, and time barriers that would otherwise limit access to another infant feeding option,” Egger said. Biomilq isn’t superior to breast milk. The American Academy of Pediatrics recommends babies exclusively breastfeed for the first six months of life since extensive research links breastfeeding with a host of physical and mental health benefits for both the birthing parent and baby, including protection from childhood leukemia and bonding between parent and infant. Formula — while “a safe, relatively affordable, thoughtfully designed, rigorously tested, and continually improving” alternative, according to pediatrician Dr. Kelly Fradin — can’t replicate all of those benefits since it’s not human-made. Instead, it comes from cows, plants, or both. Formula can also be harder for the baby to digest and doesn’t adapt to the infant’s changing needs like breast milk. Biomilq’s founders don’t claim their product is identical to breast milk in every way — it doesn’t morph to a specific baby’s needs, offer the same protections for a baby’s immune system, or reflect a mother’s diet. “We have no intention to replace chestfeeding, so we’re comfortable with the differences between our product and breast milk,” Egger said in the press release. “Instead, we intend to offer parents another supplemental feeding option to nourish healthier babies.” The product could especially benefit non-biological parents and babies with allergies.(SD-Agencies) |
