Stem Cells from Corpses?

pretty gross, but cool.

Quote:
Stem cells can remain alive in human corpses for at least 17 days after death, researchers say.

Stem cells give rise to all other cells in the body, a property that makes them extraordinarily valuable in potential therapies. These potent cells are often rare, only present in small numbers in tissue samples from patients and difficult to distinguish from other cell types in many cases. As such, scientists are investigating novel ways to procure stem cells and improve the viability of the ones they can get.

Past research had suggested that stem cells could actually survive in up to 2-day-old cadavers, but researchers had thought that dead bodies would be poor homes for any cells, lacking the oxygen and nutrients the body's cells need to stay alive. Nevertheless, histologist and neuropathologist Fabrice Chrétien at the Pasteur Institute in Paris and his colleagues were curious to see how long stem cells might keep ticking after a person died.

The researchers only had access to remains 17 days old, suggesting they have not yet seen the limits that stem cells ca reach. "Maybe they can also resist longer," Chrétien told LiveScience.

The cadavers in question had been kept at 39 degrees F (4 degrees C) to keep from rotting. The stem cells the researchers isolated give rise to skeletal muscle, the kind connected to the bones, as opposed to the kind in the heart or other internal organs. [The Science of Death: 10 Tales from the Crypt & Beyond]

Apparently the stem cells were able survive in the total absence of oxygen. "These cells are so resistant to extreme and deleterious conditions that they stay alive up to 17 days after death," Chrétien said.

The researchers also recovered viable stem cellsfrom mice 14 days after death. These cells appeared to function properly after they were transplanted into living mice, helping regenerate damaged tissues.

Re: Stem Cells from Corpses?

Anyone remember The Fifth Element? Possibly, this could lead to something like that in the far far future!

Genetic engineering is way off that yet, get a tiny thing wrong and you'll have a fucking lung growing out your forehead.
