Regenerative Medicine and Stem Cells Technologies

Many salamanders can readily regenerate a lost limb, but adult mammals, including humans, cannot. Why this is the case is a scientific mystery that has fascinated observers of the natural world for thousands of years.

A new class of hydrogels leverage light for better drug delivery and regenerative medicine treatment. Hydrogels are commonly used inside the body to help in tissue regeneration and drug delivery. However, once inside, they can be challenging to control. A team of researchers led by Professor Akhilesh Gaharwar of Texas A&M University is developing a new way to manipulate the gel — by using light.

A gene linked to unusually long lifespans in humans protects brain stem cells from the harmful effects of stress, according to a new study by Weill Cornell Medicine investigators.

The chances of restoring fertility through sperm stem cell transplant are as random as a coin toss. But a team of scientists developed a new strategy that serves as a 'weighted coin' that can favorably rig the odds to achieve outcomes where fertility is successfully restored.

One of the enduring mysteries of the COVID-19 pandemic is why most children tend to experience fewer symptoms than adults after infection with the coronavirus.
