Stem Cells

Scientists have come up with a new tool to study the way cancerous cells can hide away in body tissues and spring back into action once the danger appears to have passed, with a new hydrogel that turns different cancer cells into cancer stem cells.

An analysis of 13 case histories has found intravenous injections of stem cells lead to motor function improvements in patients with spinal cord injury. The research claims the therapy is safe but clinical trials are needed to further affirm efficacy.

A breakthrough study from scientists in Japan has homed in on the specific characteristics of stem cells responsible for hair cell regeneration and identified the optimal ingredients to generate continual hair follicle growth.

Glaucoma can cause vision loss that's currently irreversible. But now scientists have found that removing a membrane in the eye could help transplanted cells migrate into the optic nerve and repair the connections, potentially restoring lost vision.

Researchers have developed a drug that can mimic inflammation signals to lure stem cells to damaged tissue, without causing any further inflammation. The technique could be a boon for regenerative medicine to treat neurological disorders.

A new study led by the University of Edinburgh has identified a protein that plays a crucial role in protecting the body’s blood stem cells from damage during infection, a finding that could lead to new ways to slow down the aging process.

Stem cells could help treat a variety of diseases. A new study has found that transplanting neurons grown from stem cells into the brains of mice with Parkinson’s disease repaired the damaged brain circuits, improving the animals’ motor skills.

For some time now, we've heard about scaffolding-like materials that are implanted into bone fractures, prompting the body's own bone cells to grow into them and heal the break. Now, however, scientists have developed a special bandage that may also do the job.

Scientists have created the first-ever functional miniature human hearts in the lab. Grown from stem cells, these heart “organoids” are made up of all primary heart cell types, and could help build better models for treating disease.

Like most machines, the human body tends to wear out faster at the points of articulation, where decades of stress are focused. Now, researchers at Stanford have found a way to induce cartilage tissue to regenerate in joints by tweaking the stem cells there.

Heart attacks are a leading cause of death, largely because damage caused by one can lead to more. Now researchers at Rice University have developed a new way to repair heart tissue and reduce scarring, by implanting capsules loaded with stem cells.

Goosebumps are a weird quirk of our bodies that science doesn’t fully understand. Now, researchers at Harvard have uncovered a biological reason for the reaction: it’s our bodies’ way of stimulating stem cells to drive new hair growth.
