Here are various news reports about stem cells, regenerative medicine, and other aspects of continually advancing medical science; collated for the improvement of your intelligence.

The Guardian wrote (26 Nov 2014) regarding a spinal cord being grown in the lab: "As regenerative medicine and stem cell technologies continue to progress, so the list of tissues and organs that can be grown from scratch – and potentially replaced – continues to grow. In the past few years, researchers have used stem cells to grow windpipes, bladders, urethras and vaginas in the lab, and, in some cases, successfully transplanted them into patients."

29 Oct 2014, The Guardian reported how mini-stomachs had been grown via stem cells. This would be useful for tissue repair and disease testing in the lab. The Guardian wrote: “This is not the first time that miniature organs have been grown from stem cells. In 2013, scientists grew miniature kidneys and successfully transplanted into a rat. Replacement windpipes, grown from stem cells on lab-made scaffolds, have also been grown and transplanted into patients.”

Stem cells could repair damage from Parkinson's disease. Research using a rat model shows how new dopamine-producing cells can be created then integrated into the brain. The National Health Service in the UK wrote (7 Nov 2014): “Up to six months after the cell transplant, brain scans and functional tests showed that the transplanted cells had proliferated and matured, reinnervated the brain tissue, and were producing dopamine.”

The BBC reported on the aforementioned Parkinson's issue (7 Nov 2014): “There have been no human clinical trials of stem-cell-derived neurons, but the researchers said they could be ready for testing by 2017. ”

Finger nails can regenerate if removed or lost. The #StemCells regarding this regeneration could be manipulated regarding regeneration of other body parts. Science Daily wrote (21 Nov 2014): “The researchers are now wondering whether or not the right signals or environmental cues could induce these nail stem cells to generate additional types of tissue -- potentially aiding in the repair of everything from nail and finger defects to severe skin injuries and amputations.”

The US Department of Defense reported on how syntheticbiology is being used by DARPA to thwart diseases. On 20 Nov 2014 the DoD wrote: “The 1000 Molecules effort is part of a DARPA program called Living Foundries, whose goal is to leverage the synthetic and functional capabilities of biology to create a revolutionary, biologically based manufacturing platform for novel materials, sensing capabilities and therapeutics.” And: “Another part of Living Foundries, called Advanced Tools and Capabilities for Generalizable Platforms, began in 2012 and focuses on developing next-generation tools and technologies for engineering biological systems. Its goal is to compress the biological design-build-test-learn cycle by at least 10 times in time and cost as it creates more complex systems.”

Live Science reported (14 Oct 2014) regarding stem cells partially restoring sight for blind people: “The results show that human embryonic stem cells can slow or reverse the vision loss in people with degenerative eye diseases, the researchers said.”

The NHS (UK) also commented on the issue of stem cells restoring sight (15 Oct 0214): “Overall, these studies show a promising treatment for two of the commonest causes of visual impairment in the developed world, though it will take a few more years of trials to optimise the technique.”

The Independent wrote (9 Oct 2014) regarding a looming cure for diabetes, based on stem cells being transformed into functional pancreatic cells: “The researchers screened about 150 different chemicals and found 11 that in combination could be used to coax human stem cells into fully-mature beta pancreatic cells, which were found to produce reliable and meaningful quantities of insulin when transplanted into diabetic mice. ”

On 19 Nov 2014 Time reported how stem cells had cured severe combined immunodeficiency, SCID. They wrote: “Evangelina, a twin, was born with a severe immune disorder caused by a genetic aberration that makes her vulnerable to any and all bacteria and viruses; even a simple cold could be fatal. But doctors at University of California Los Angeles (UCLA) Broad Stem Cell Research Center gave her a new treatment, using her own stem cells, that has essentially cured her disease. ”

Huffington Post, 22 Nov 2014: "I am convinced that stem cell research means we Baby Boomers will be the last generation to have to watch our parents die of Alzheimer's or watch our children die prematurely of sickle cell disease."
