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

Cloning used to make stem cells

For the first time, cloning technologies have been used to generate stem cells that are genetically matched to adult patients.

Fear not: No legitimate scientist is in the business of cloning humans. But cloned embryos can be used as a source for stem cells that match a patient and can produce any cell type in that person (…)

“This is a dream that we’ve had for 15 years or so in the stem cell field,” said John Gearhart, director of the Institute for Regenerative Medicine at the University of Pennsylvania. Gearhart first proposed this approach for patient-specific stem cell generation in

Personalized Stem Cells for Diabetes Cure

Regenerative medicine took a step forward on Monday with the announcement of the creation of the first disease-specific line of embryonic stem cells made with a patient’s own DNA (…)

“This is a really important step forward in our quest to develop healthy, patient-specific stem cells that can be used to replace cells that are diseased or dead,” said Susan Solomon, chief executive officer of NYSCF, which she co-founded in 2005 partly to search for a cure for her son’s diabetes.

Stem cells could one day be used to treat not only diabetes but also other diseases, such as Parkinson’s and
