Stem Cells Grow Artificial Eyeballs
Embryonic stem cells growing in a dish can spontaneously form complex structures resembling the retina—a discovery that could one day help restore sight to the blind.
"A clump of mouse embryonic stem cells can self-organize into three-dimensional structures reminiscent of the retina in the early stages of embryonic development," according to a new study published in Nature. What was especially astounding about the research is that the cells were not manipulated in any way to take the shape of organ. This suggests that the shape for organs is internally programmed into stem cells. "Researchers believe this process could one day serve as a source of cells to transplant into diseased and damaged retinas—a potential way to restore sight to the blind."
Both schizophrenics and people with a common personality type share similar brain patterns.
- A new study shows that people with a common personality type share brain activity with patients diagnosed with schizophrenia.
- The study gives insight into how the brain activity associated with mental illnesses relates to brain activity in healthy individuals.
- This finding not only improves our understanding of how the brain works but may one day be applied to treatments.
It's a development that could one day lead to much better treatments for osteoporosis, joint damage, and bone fractures.
- Scientists have isolated skeletal stem cells in adult and fetal bones for the first time.
- These cells could one day help treat damaged bone and cartilage.
- The team was able to grow skeletal stem cells from cells found within liposuctioned fat.
Gut bacteria play an important role in how you feel and think and how well your body fights off disease. New research shows that exercise can give your gut bacteria a boost.
- Two studies from the University of Illinois show that gut bacteria can be changed by exercise alone.
- Our understanding of how gut bacteria impacts our overall health is an emerging field, and this research sheds light on the many different ways exercise affects your body.
- Exercising to improve your gut bacteria will prevent diseases and encourage brain health.
