Creating hairy human skin: Not as easy as you think
Key takeaways· Scientists have created the first cultured human skin capable of growing hair embedded with fat and nerve cells. · Potential applications include burn treatments, and testing medications and cosmetics· The skin organoid system developed is a proof of concept for creating other human organoids, such as the inner ear. For more than 40 ... Read More
Gene therapy with a new base editing technique restores hearing in mice
Using a new genetic engineering technique, known as base editing, researchers from Boston Children’s Hospital and the Broad Institute of MIT and Harvard, have restored hearing in mice with a known recessive genetic mutation. Key takeaways· This is the first example of repairing a recessive gene mutation.· Repairing a single mutation in the Tmc1 gene restored partial hearing in ... Read More

Optimized CRISPR/Cas9 gene editing averts hearing loss in ‘Beethoven’ mice
Using a novel gene-editing approach, scientists at Boston Children’s Hospital and Harvard Medical School have salvaged hearing in a mouse model of hereditary deafness, with no apparent off-target effects. The system successfully identified a single misspelled “letter” in the defective copy of a gene required for hearing, disabled this aberrant copy, and spared the healthy ... Read More

Gene therapy restores hearing in deaf mice
More than 70 different genes are known to cause deafness when mutated. Jeffrey Holt, PhD, envisions a day when patients with hearing loss have their genome sequenced and their hearing restored by gene therapy. A proof-of-principle study published today by the journal Science Translational Medicine takes a clear step in that direction, restoring hearing in deaf mice. “Our gene ... Read More

How things work: Scientists find cellular channels vital for hearing
Ending a 30-year search by scientists, researchers have identified two proteins in the inner ear that are critical for hearing, which, when damaged by genetic mutations, cause a form of delayed, progressive hearing loss. The proteins are essentially transducers: They form channels that convert mechanical sound waves entering the inner ear into electrical signals that ... Read More
Gene-therapy trial will attempt to restore hearing in deaf mice
Sound waves produce the sensation of hearing by vibrating hair-like structures on the inner ear’s sensory hair cells. But how this mechanical motion gets converted into electrical signals that go to our brains has long been a mystery. Scientists have believed some undiscovered protein is involved. Such proteins have been identified for taste, smell and ... Read More
