JERUSALEM, July 14 (Xinhua) -- Israeli researchers have found a way to use stem cells to help dairy cows stay healthier and produce more nutritious milk, the Hebrew University of Jerusalem (HU) said Monday.
Milk fat is not only important for taste, but also provides key nutrients such as energy, vitamins A and D, and essential fatty acids. However, modern dairy cows often experience significant stress on their udder, which leads to chronic inflammation and mastitis.
The new study, published in Stem Cell Research & Therapy, showed that molecules released by mesenchymal stem cells, known as "secretome," can calm inflammation in milk-producing cells and boost the fat content of milk, resulting in creamier and more nutritious milk.
The study found that in lab tests, when mammary cells were exposed to stem cells or their secretions, inflammation dropped even under stress, and fat-related gene activity and triglyceride production increased, read the statement.
The positive effects do not require the actual use of stem cells -- the molecules alone produced the benefits, meaning they could one day be used as a feed additive or supplement for cows, read the statement. Enditem
