The first world bank storing stem cells taken from amniotic fluid is “made in Italy”: it’s a private hospital in Busto Arsizio, near Milan.
Women planning amniocentesis – removal of amniotic fluid from the uterus (test done during pregnancy) – can ask for the “conservation set”, which will be given to the gynaecologist.
3 millilitre of amniotic liquid are enough to find some particular kind of stem cells very close to embryonic stem cells and suitable for in vitro breeding.
Then the test tube will be sent to the company which will store it for 20 years at -320°F. Some “experts” says that those cells are not enough for getting necessary cells for a cure.
Researchers said on Sunday they had found a safer way to transform ordinary skin cells into powerful stem cells in a move that could eventually remove the need to use human embryos.
It is the first time that scientists have turned skin cells into induced pluripotent stem cells or iPS cells — which look and act like embryonic stem cells — without having to use viruses in the process.
The new method also allows for genes that are inserted to trigger cell reprogramming to be removed afterwards.
Stem cells are the body’s master cells, producing all the body’s tissues and organs.
Embryonic stem cells are the most powerful kind, as they have the potential to give rise to any tissue type. However, many people object to their use, making iPS cells an attractive alternative, provided they can be made safely.
Researchers have known for some time that ordinary skin cells can be transformed into iPS cells using a handful of genes.
But to get these genes into the cells they have had to use viruses, which integrate their own genetic material into the cells they infect. This can cause cancer.
The alternative approach, described in the online edition of the journal Nature by two teams of researchers from Britain and Canada, appears to avoid the risk of such abnormalities.
The researchers harnessed a little piece of DNA called a transposon — sometimes known as a “jumping gene” because of its ability to move around inside the genetic code — to carry four genes.
For the first time in the United States, stem cells have been directly injected into the spinal cord of a patient, researchers announced Thursday.
Doctors injected stem cells from 8-week-old fetal tissue into the spine of a man in his early 60s who has advanced ALS, or amyotrophic lateral sclerosis. It was part of a clinical trial designed to determine whether it is safe to inject stem cells into the spinal cord and whether the cells themselves are safe (…)
Advancements in stem cell research may one day help surgeons provide treatment for Amyotrophic Lateral Sclerosis (ALS), also known as Lou Gehrig’s disease, a deadly neurodegenerative disease characterized by the selective death of motor neurons.
CD133+ stem cells are known to have the capacity to differentiate into neural lineages and may provide an alternative treatment for patients suffering from ALS and other neurodegenerative diseases.
According to Newswise, Linda Kelley, Ph.D., director of the University of Utah’s Cell Therapy Facility, James Campanelli, Ph.D., of University of Utah spin-out Q Therapeutics, Inc., and Utah native Nicholas Maragakis, M.D., of The Johns Hopkins University School of Medicine have teamed up to bring the cell-based therapy to the point of human clinical trials to treat this deadly disease.

A research group at Imperial College London has designed a new treatment able to significantly improve the body’s capacity to repair damage caused by a heart attack or bone fracture. The new therapy, described in Cell Stem Cell, ‘fools’ the spinal cord inducing it to ’overproduce’ stem cells which repair damaged tissues in the body. Researchers hope to test the treatment on animals by the end of the year. If testing is successful, the next step will be to experiment on human beings attempting to induce them to use their own stem cells to regenerate damaged or infected organs.
