When a neuron ages, it loses synaptic connections with other neurons, it is less able to transmit nerve impulses, and its metabolism is also altered. This process of neuronal aging—inevitable with the ...

A new study has shed light on the challenges of converting one type of specialized cell into another, a process critical for advances in regenerative medicine. Despite recent progress in the field, a ...

Aging, at its most fundamental level, is a molecular process. Chemical marks on the genome shift and lose fidelity over time, ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? Here’s what you’ll learn when you read this story: A scientist wants to reprogram ...

A team led by researchers at the University of Toronto has discovered that a group of cells located in the skin and other areas of the body, called neural crest stem cells, are the source of ...

Blindness itself might become, at least in certain cases, partially reversible. This potential future stems from one of the ...

A mature cell of one type can be turned into a mature cell of another type without the cell having to pass through an earlier stage of development. This is called direct reprogramming, a reliable but ...

Promising mouse studies and billions of dollars in funding are stoking excitement. But we’ve been here before.

A new study reveals that reprogramming specialized cells to become different types of cells, a key process in regenerative medicine, faces a major hurdle. The challenge lies in the DNA methylation ...
