Life in the corpse is 17 days

Stem cells can live at least 17 days in a dead body, according to a recent study by scientists at the Pasteur Institute, France.

When the corpse approached was dead for 17 days, the research team at the Pasteur Institute found that stem cells were still "alive" , and that this was not their final survival limit. Neuroscientist, Fabrice Chrétien, lead researcher on LiveScience: 'It is possible that stem cells last longer.'

The study conducted with cadavers stored at 4 degrees Celsius, with stem cells separated was the musculoskeletal stem cell."These cells are resistant to harsh and harsh conditions that live up to 17 days in a dead body ," Chrétien said.

Stem cells are the basal cell from which the cell types of the human body are created. This is an extremely valuable trait in treating diseases.

Stem cells continue to live in the body that died 17 days.

However, these cells are often rare, rarely appear in the patient's tissue samples and are difficult to distinguish from other cell types. So scientists are studying new methods to create stem cells and improve its viability.

Previous research has suggested that stem cells can survive for 2 days in corpses. But according to scientists, corpses are not the ideal environment for any cell, due to lack of oxygen and nutrients that the body's cells need to sustain life.

The team also found that stem cells survived 14 days in mice. These cells still function normally after transplanting into the body of a living mouse and help it recreate the damaged tissue.

However, Chrétien emphasized: 'This does not mean we will use cells from dead bodies for a long time to treat patients. For clinical treatment, we only use cells from new bodies that die a few hours. "

Human stem cells and rats were found to be in the form of 'hibernation' , the metabolic activity was significantly reduced. This is the first time scientists have discovered that stem cells are able to hibernate for so long.

Researchers speculate, or chemicals that appear after death or low levels of oxygen and nutrients in the body or combine all of these factors, may cause stem cells to fall into hibernation, helping them survive. at weekly.

Deep understanding of this hibernation can create new ways to help stem cells survive longer, serving for therapeutic purposes.
