Alternde Haut, die durch junges Blut und Knochenmark verjüngt wird – Eine neue Studie zeigt, dass Proteine, die von Knochenmarkzellen sekretiert werden und durch junges Blut ausgelöst werden, die alternde Haut im Labor verjüngen können.

Aging skin rejuvenated by young blood and bone marrow

From vampire legends to lab-grown tissue, the idea that young blood can reverse aging is no longer pure myth. A new study shows that proteins secreted by bone marrow cells, triggered by young blood, can rejuvenate aging skin in the lab.

Well, science may well have caught up with myth. A new study out of Germany, led by the Research and Development arm of skin care company Beiersdorf AG, has examined whether young human blood contains factors that can rejuvenate aging skin. In short, they found that it can – but only in the presence of blood marrow cells.

Using proteomics, the researchers identified 55 age-related proteins secreted by the bone marrow model in response to young serum. Of these, seven showed clear anti-aging effects when tested directly on aged human fibroblasts (cells that form connective tissue) and keratinocytes (the major cell type of the outermost layers of the skin) in the lab. Benefits included more cell division, higher collagen production, better mitochondrial health, and an increased ability to convert into fat-like cells, which is a sign of regenerative flexibility.

Feels like virtually zero actual progress is being made – just the same old „young blood“ and „vitamins“ bullshit we’ve had for the past 50+ years.
