Taking the piss out of stem cell squabblers



Human neural stem cells hold great promise for research and therapy in neural disease. We describe the generation of integration-free and expandable human neural progenitor cells (NPCs). We combined an episomal system to deliver reprogramming factors with a chemically defined culture medium to reprogram epithelial-like cells from human urine into NPCs (hUiNPCs). These transgene-free hUiNPCs can self-renew and can differentiate into multiple functional neuronal subtypes and glial cells in vitro. Although functional in vivo analysis is still needed, we report that the cells survive and differentiate upon transplant into newborn rat brain. [via Article, IMG]



Meaning researchers have developed a method that transforms the cells in human urine into precursors of brain cells. The idea: cells from urine > than stem cells since they are easier to get and the risk of embryonic tumor development isn’t a concern. Also, it’s a crafty way for lemon party goers to support and fund raise for neurodegenerative treatment research.

Awareness detected in people in vegetative state

The highlights:

Scientists have used a portable device that tracks changes in brain waves to communicate with people in a vegetative state, some of whom have been locked in their bodies for more than a year.

The researchers instructed 16 people in a vegetative state to imagine they were making a fist with their right hand or wiggling their toes, and then measured brain activity while electrodes were attached to their scalp.

"It was possible to detect that these patients were actually aware" despite being diagnosed as being "entirely unconscious" using standard clinical assessments, said Professor Adrian Owen of the Center for Brain and Mind at the University of Western Ontario. 

Curiously, three of the 12 healthy volunteers were not able to reliably activate areas in the brain used when making a fist or wiggling toes, even though they were very much aware of their surroundings.

Cruse said patients in a vegetative state may have been much more motivated to do the task because they were eager to show that they were aware of their surroundings. via

Rock Soup: Our Mission Statement

Six months after a 7.0 earthquake left 230,000 dead and more than 1.5 million people homeless, Haiti continues to be in dire need of assistance rebuilding its fragile infrastructure. We thought this would be a good time to post the Rock Soup Project mission statement. We’re anxious to get this…
