Adult stem cell discovery

VATICAN CITY (CNS): Italian researchers have developed a method to repair a damaged heart using adult stem cells, and said it confirmed that the adult cells were more therapeutically useful than embryonic stem cells.

“The adult stem cell is already prepared to differentiate in the tissue we want to repair. And it is certainly more productive, less wasteful and less dangerous – beyond the ethical aspects – to work with adult stem cells instead of embryonic stem cells,” Settimio Grimaldi, who is an expert at the Institute of Neurobiology and Molecular Medicine in Rome, which carried out the research, said.

Mr Grimaldi spoke on August 15 to Vatican Radio, which hailed the published results as an important advance in stem-cell therapy.

The Italian team developed a new method of isolating cardiac stem cells, cultivating them and injecting them in such a way that they replace damaged tissue; after testing on animals, the researchers hope to apply the method on humans in about three years.

He said the method should be able to help people who have suffered heart attacks lead a fairly normal life, including work and sports activities.

“The frontier of regenerative medicine is opening, and this in our opinion is the medicine of the future,” he said.

Church experts have long argued that the use of adult stem cells is not only ethically acceptable but appears to be more promising on a practical level, and Mr Grimaldi agreed.
