Some stem cells can lay dormant for more than two weeks in a dead person and then be revived to divide into new, functioning cells, scientists in France said.
The research, published in the journal Nature Communications, unlocks further knowledge about the versatility of these cells, touted as a future source to replenish damaged tissue.
“Remarkably, skeletal muscle stem cells can survive for 17 days in humans and 16 days in mice, post mortem well beyond the 1-2 days currently thought,” they said in a statement.
The stem cells retained their ability to differentiate into perfectly functioning muscle cells, they found.
Although a growing number of people today are stricken with cancer – the leading cause of death in France since 2004 – their risk of succumbing to this disease is dropping. Nationwide mortality rates continue to vary, most notably on a regional level, as was demonstrated in the distinguished Atlas de la mortalité par cancer en France metropolitaine [Atlas of cancer death in mainland France (excluding overseas territories)], published on January 28. On a generalized basis, the numbers for Northern and Central France clearly point to hypermortality while death rates in the southern portion of the country were lower

On May 6, France’s Council of State (the highest administrative court and legal advisor to the executive branch) declared that it was against the practice of “renting out one’s uterus” and in favor of the permanent authorization regulations for embryo research and embryonic stem cell research under certain conditions. French Prime Minister Francois Fillon had asked the court for its opinion, in a reexamination of a 2004 bioethics law.

The Pisa University Hospital has become part of the international network of hematopoietic stem cell transplant facilities (meaning they produce various blood components). The hospital was recently accredited by the Italian registry of bone marrow donors, which is part of the international network.
Pisa has become an important center for bone marrow collection for all potential donors in northwestern Italy.
On 20 April 2009, the first donation was carried out for a patient at the Udine University Hospital, and a second donation is being organized for a patient being treated at the Montpellier Hospital (France).
The hospital in Pisa received the
