Men with type 1 diabetes may be able to grow their own insulin-producing cells from their testicular tissue, say Georgetown University Medical Center (GUMC) researchers who presented their findings.
Their laboratory and animal study is a proof of principle that human spermatogonial stem cells (SSCs) extracted from testicular tissue can morph into insulin-secreting beta islet cells normally found in the pancreas. And the researchers say they accomplished this feat without use of any of the extra genes now employed in most labs to turn adult stem cells into a tissue of choice.
“No stem cells, adult or embryonic, have been
In a breakthrough, Harvard scientists have discovered that stem cells loaded with the herpes virus can be used to specifically target and kill brain tumours.
Harvard Stem Cell Institute (HSCI) scientists at Massachusetts General Hospital have a potential solution for how to more effectively kill tumour cells using cancer-killing viruses.
The work, led by Khalid Shah, an HSCI Principal Faculty member, found that trapping virus-loaded stem cells in a gel and applying them to tumours significantly improved survival in mice with glioblastoma multiforme, the most common brain tumour in human adults and also the most difficult to treat (…)

University of Michigan researchers have proven that a special surface, free of biological contaminants, allows adult-derived stem cells to thrive and transform into multiple cell types. Their success brings stem cell therapies another step closer.
To prove the cells’ regenerative powers, bone cells grown on this surface were then transplanted into holes in the skulls of mice, producing four times as much new bone growth as in the mice without the extra bone cells.
An embryo’s cells really can be anything they want to be when they grow up: organs, nerves, skin, bone, any type of human cell. Adult-derived “induced” stem
Warnings are being issued by experts of the dangers of medical tourism saying that unproven stem cell therapy overseas could leave patients worse off.
Signing up for stem cell therapy is worth the risk for many people who are suffering with conditions like spinal injury, multiple sclerosis, motor neuron or Parkinson’s disease.
A medical journal reported earlier this year that an Israeli teenager developed brain tumors after experimental injections at a Russian clinic.
There are alternate reports also of patients contracting meningitis after treatments in China.
A handbook will be released by the Australian Stem Cell Centre to help patients analyze radial stem
Study May be Key to Unlocking a Cure
An article published in the Summer 2009 edition of Multiple Sclerosis Quarterly Report, a joint publication of United Spinal Association (www.UnitedSpinal.org) and the North American Research Committee on Multiple Sclerosis (NARCOMS), highlights the positive initial results of patients who have improving neurologic function after receiving a stem cell transplant, despite no longer taking any MS medications.
The results are reported in a National Institutes of Health (NIH)-sponsored study called HALT-MS to confirm whether high-dose immunosuppression followed by autologous stem cell transplantation will prevent MS attacks in patients who are not responding to available
