Simple ex vivo or in vitro models are most useful for testing putative cell therapy protocols, as they allow quick and controlled screening of variants and possible improvements. We discuss here ...

Imagine you could grow a new limb or a new organ. We would be able to live forever if that were the case. However, while we cannot grow new limbs, our bodies still react in pretty miraculous ways when ...

BACKGROUND: Direct reprogramming of fibroblasts to cardiomyocytes is a potentially curative strategy for ischemic heart ...

Cardiac side population cells. Side population cells, which are defined by their differential ability to efflux the DNA-binding dye Hoechst 33342, a process dependent on the expression of P ...

Humans can't regenerate heart muscle damaged by disease, but scientists have long known that some animals, such as zebrafish, can.Researchers have now ...

Zebrafish have the remarkable and rare ability to regrow and repair their hearts after damage. New research from Caltech and UC Berkeley has identified the circuit of genes controlling this ability ...

Research led by the National Institute of Biological Sciences in Beijing has discovered that switching on a single dormant ...

A new study reveals the key lies not in the production of a regrowth molecule, but in that molecule's controlled destruction.

Molecular signals after severing an axolotl arm direct the remaining cells how to regrow the limb, offering potential ...

Chinese scientists who discovered a 'genetic switch' that restored damaged mice ear tissue say their research could one day ...

A new study by scientists from Baylor College of Medicine in the U.S. and the QIMR Berghofer Medical Research Institute in ...

We were trying to learn how certain animals lost their regeneration capacity during evolution and then put back the ...
