Once we lose the sensory hair cells in the cochlea, they’re gone for good. But now researchers have found a way to regrow them in mice, potentially paving the way for more effective hearing loss treatments in humans.

Chinese researchers have successfully managed to breed healthy mice with genetic material from two mothers, using stem cells and gene editing.

A novel form of treatment could help cut back on a person’s desire for cocaine and reduce its damaging effect in the body. The method involves removing a small patch of skin, introducing genes that produce cocaine-degrading enzymes, and then grafting it back onto the patient.

Teeth can’t naturally repair themselves – so when a kid injures a permanent tooth at a young age, they’re stuck with that for life. But a new clinical trial has shown promising results in using dental stem cells derived from a patient’s baby teeth to bring a “dead” tooth back to life.

Georgia Tech researchers have developed a hydrogel that holds muscle stem cells, and by injecting this near the site of a muscle injury they can get to work repairing it. The team says the technique could be effective at treating injuries in the elderly and people with muscular dystrophy.

Researchers at the University of Minnesota have designed a silicone device, covered in 3D-printed neuronal stem cells, that can be implanted into a spinal injury. There it grows new connections between remaining nerves to let patients regain some motor control.

A large trial has just been launched in the UK exploring the use of stem cells for treating patients with Crohn's disease. The radical treatment involves essentially "rebooting" a patient's immune system and has been used successfully in the past for multiple sclerosis and some cancers.

Researchers in Japan are making exciting progress on a way to potentially arrest the deterioration of motor skills in Parkinson's patients. They are now preparing to begin transplanting reprogrammed stem cells into human brains as part of a first-of-a-kind clinical trial.

Scientists have created the most lifelike artificial embryos ever, guiding them through “the most important event in life” – a key development stage known as gastrulation. The researchers combined three types of mouse stem cells into an embryo that was just about ready to be implanted into a womb.

In breakthrough new research described as "somewhat mind-boggling," a team at Stanford University has developed a technique than can transform human immune cells found in a regular blood sample into functional neurons in just three weeks.
