Researchers studying a 5,300-year-old body found frozen in the Italian Alps in 1991 say they found red blood cells around his wounds, the oldest ever seen.
Hikers discovered "Oetzi the Iceman" with an arrow buried in his back, and researchers had already determined he died from his wounds.
The frozen body is remarkably preserved, and scientists writing in the Journal of the Royal Society say that preservation extends to the bleeding that occurred before his death, the BBC reported Wednesday.
Blood cells degrade quickly, and earlier searches for blood within the frozen body showed no signs of blood cells, researchers said.
Albert Zink and colleagues at the Eurac Institute for Mummies and the Iceman in Bolzano, Italy, have now used a technique known as atomic force microscopy to examine thin slices of tissue taken from an area around the arrow wound and discovered structures with the tell-tale "doughnut" shape of red blood cells.
They are by far the oldest red blood cells ever observed, researchers said.

Genes shed light on spread of agriculture in Stone Age Europe
Uppsala, Sweden (SPX) May 04, 2012
One of the most debated developments in human history is the transition from hunter-gatherer to agricultural societies. This week's edition of Science presents the genetic findings of a Swedish-Danish research team, which show that agriculture spread to Northern Europe via migration from Southern Europe. "We have been able to show that the genetic variation of today's Europeans was strongl ... read more
