Young-Blood Proteins May Rejuvenate Human Skin
Blood from the bone marrow of younger individuals may hold potential for rejuvenation, slowing or even reversing some signs of skin aging, according to new research. Scientists found that certain cells from bone marrow release substances that appear to boost skin renewal, but the benefits were only seen when these bone marrow–derived cells were present. […]
New research suggests that blood from younger bone marrow cells could potentially rejuvenate human skin, offering hope for future anti-aging treatments. Scientists discovered that certain bone marrow-derived cells release substances that promote skin renewal, but only when present alongside the cells. The study, led by skincare company Beiersdorf AG, builds upon previous experiments involving mice, where older mice exposed to younger blood developed healthier tissue.
To test the concept in humans, researchers used a lab model combining human skin and bone marrow stem cells. Blood serum from individuals under 30 and over 60 was introduced to the model, with only the younger serum leading to improvements in the skin. These younger samples triggered the release of 55 proteins, seven of which were found to stimulate skin cell growth, reduce biological aging, and enhance cellular energy production.
While this research holds promise, experts emphasize the need for further studies to confirm the findings and ensure the safety and efficacy of any resulting treatments.
