Stem Cells: fight diabetes using …sperm!

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

Stem cells against brain cancer

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 (…)

Stem-cell-growing surface enables bone repair

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

United Spinal Association Reports Positive Results of Stem Cell Transplantation to Treat Multiple Sclerosis

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

Stem Cell Research Trial For Liver Patients Using Adult Stem Cells

Stem Cell Research Trial For Liver Patients Using Adult Stem Cells
In a stem cell research trial that isn’t getting enough news, liver patients are now being treated with their own Adult Stem Cells at Hammersmith Hospital in London, England. They have treated more than 30 patients now with “good results.” This […]
