| Scientists managed to grow the hair cells vital to hearing in the cochleas of genetically modified mice. |
| Most of them design their artificial cochleas just like thin membrane with different width along its length. |
| Researchers at Genentech in South San Francisco now report that they've grown new hair cells in tissue taken from newborn rats' cochleas. |
| A difference, however, was seen between the implanted ungrafted and the implanted grafted cochleas but not between the use of fascia and Gelfoam. |
| After receiving an injection of the drug in the ear, mice with cochleas damaged by loud white noise sprouted new hair cells. |
