Stem cell breakthrough: Monitoring the on switch that turns stem cells into muscle

Image via Wikipedia

In a genetic engineering breakthrough that could help everyone from bed-ridden patients to elite athletes, a team of American researchers—including 2007 Nobel Prize winner Mario R. Capecchi—have created a “switch” that allows mutations or light signals to be turned on in muscle stem cells to monitor muscle regeneration in a living mammal. For humans, this work could lead to a genetic switch, or drug, that allows people to grow new muscle cells to replace those that are damaged, worn out, or not working for other reasons (e.g., muscular dystrophy). In addition, this same discovery also gives researchers

Warning issued against stem cell tourism by experts

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

Cancer stem cells existence proven in humans

Scientists have found the first “conclusive evidence” of the existence of cancer stem cells in humans, in a discovery which could put an end to years of scientific controversy and pave the way for more effective cancer treatments which could attack the disease “at the root” (…)

The existence of cancer stem cells – mutated stem cells responsible for the development and growth of cancers – has been hypothesised for decades, and their existence in mice was established two years ago. Whether or not they are also responsible for the growth of cancers in humans has remained controversial (…)

British team pioneers reconstruction technique using enriched tissue

A remarkable reconstruction technique is being trialled by British surgeons, who are harvesting stem-cell-enriched fat from women’s bodies to plug the dip often left by breast cancer operations.
The procedure appears to restore the softness and suppleness of breast tissues, undoing the damage frequently caused by lumpectomy and radiotherapy. Early signs indicate that it also eases the considerable pain with which patients are often left after treatment.

More than 31,000 women a year in Britain with early-stage breast cancer undergo operations in which just the lump and a healthy margin of tissue

UWM researcher makes breakthrough in stem cell technology

UW-Milwaukee researcher Andrew Cohen has successfully developed a software program that facilitates predicting the evolution of stem cells. The program essentially speeds up what has been a tedious process for researchers in the past.

The program was published last week in the journal Nature Methods. It applies algorithmic information theory to the growth and movement of stem cells tracked over time to show what type of cells (i.e. brain, skin, etc.) they will eventually develop into.

“People look at images and take measurements by hand,” Cohen explained. “It takes a long time, and using computers makes the process a
