An experimental treatment in Spain has shown promising possibilities to rebuild breasts damaged by tumors with the use of fat taken from the patient’s abdomen, removing stem cells, then injecting them into the chest, in a process that takes from four to five hours and does not leave scars.
Five patients from Madrid were the first in Spain to undergo the pioneering operation performed at Gregorio Maranon in collaboration with three other European hospitals in Great Britain, Italy, and Belgium. Mesenchymal stem cells, adult stem cells with the ability to transform into different tissues, are the
“Behind the embryonic stem cell war is just a war of patents,” led an article in the Osservatore Romano newspaper by Angelo Vescovi, a geneticist at the Niguarda Hospital in Milan and a professor at the Università Bicocca, who has always been against embryonic stem cell research and supporter of ‘law 40’ (recently declared unconstitutional by authorities).
“The production of embryonic stem cells by reprogramming adult cells discovered recently is not only better than methods that use human embryos, but is also based on new techniques, which are not protected by patents that currently govern the use of stem cells

Misleading advertisements by Swedish company Labo promising hair growth and to remove wrinkles have been pulled. The jury of the self-regulating body for the advertising industry (IAP) ordered the advertisements, which were found in two important Italian newspapers, to be stopped since they were “in violation of article 2 of the self-regulatory code for advertisements”.
According to the group’s conclusions (ruling number 13/09), the statements made in the message, as noted by the IAP Surveillance Committee, “did not overstate, they were misleading”.
This is due to the fact that “they were characterized by a technical and scientific language

Scientists have made a breakthrough in stem cell research which raises the prospect of regrowing damaged sections of a person’s liver, pancreas or even their brain.
Researchers at the University of NSW have found a way to improve the lifespan and competitiveness of stem cells, overcoming a problem which otherwise saw their regenerative powers fade in about an hour.
Adult stem cells were given a gene to make them resistant to chemotherapy, handing them an “advantage” when used to treat damaged tissue in conjunction with the cancer-fighting treatment.
University of NSW Professor Peter Gunning said as the chemotherapy cleaned out
The same genes that are chemically altered during normal cell differentiation, as well as when normal cells become cancer cells, are also changed in stem cells that scientists derive from adult cells, according to new research from Johns Hopkins and Harvard.
Although genetically identical to the mature body cells from which they are derived, induced pluripotent stem cells (iPSCs) are notably special in their ability to self-renew and differentiate into all kinds of cells. And now scientists have detected a remarkable if subtle molecular disparity between the two: They have distinct “epigenetic” signatures; that is, they differ in what gets
