“Liposuction leftovers” easily converted to induced pluripotent stem cells

Globs of human fat removed during liposuction conceal versatile cells that are more quickly and easily coaxed to become induced pluripotent stem cells, or iPS cells, than are the skin cells most often used by researchers, according to a new study from Stanford’s School of Medicine. The findings were published online Monday in the Proceedings of the National Academy of Sciences.

“We’ve identified a great natural resource,” said Stanford surgery professor and co-author of the research, Michael Longaker, who has called the readily available liposuction leftovers “liquid gold.” Reprogramming adult cells to function like embryonic stem

Stem cells from aged, damaged hearts could be used to treat heart failure

A new research has suggested that cardiac stem cells – even in elderly and sick patients – could generate new heart muscle and vessel tissue and be used to treat heart failure.

Scientists surgically removed tissue from the muscular wall of the heart’s chambers in 21 patients.

They then isolated and multiplied the cardiac stem cells (CSCs) found there.

Most of the patients had ischemic cardiomyopathy (enlarged and weakened muscle due to coronary artery disease). Eleven also had diabetes. The average age of patients was about 65.

“Regardless of the gender or age of the patient, or of diabetes, we were

ITALY – Undersecretary Fazio: against freedom of choice for autologous conservation of children’s stem cells by parents

Italian Welfare Undersecretary Ferruccio Fazio disapproves of private biobanks and is clearly in favor of the “allogenic” conservation of umbilical cord stem cells, meaning the conservation of stem cells saved for the exclusive use of the donor-patient. Speaking about a government report on “the appropriate use of umbilical cord stem cells”, Fazio outlined the government’s approach on the issue. A few weeks after a ministerial decree dictating new regulations for umbilical cord conservation, Fazio explained autologous donation, meaning conservation of stem cells for yourself, “is not only less useful, but also less efficient as

AUSTRIA – Embryonic stem cell research regulations loosened

Just as Barack Obama has loosened the regulations on embryonic stem cell research in the USA, the Austrian Commission of Bioethics (which advises the government) has decided to implement more liberal regulation. Today in Austria it is prohibited to produce embryonic stem cells, but it is allowed to import them from abroad. These cells are expensive and research is hindered by high costs. The majority of the Commission has advised, with a 17 to 5 vote, that the use of excess embryonic stem cells from assisted fertilization procedures be made legal.

ITALY – New technique to recognize pancreatic stem cells discovered

Image via Wikipedia

Everyone knows about the potential of stem cells in the medical field, but until today, no one had found a way to recognize them in an organ or tissue. Thanks to a new study published in the ‘Proceedings of the National Academy of Sciences’ by 2007 Nobel Prize winner for Medicine, Mario Capecchi and researcher at Cattolica University in Rome, Eugenio Sangiorgi, this obstacle has been overcome. Experts have found a new technique to find stem cells hidden in the pancreas.

“Although the journals talk a lot about this topic,” said Sangiorgi, who has collaborated with
