"The reattachment appears up to now to have proceeded optimally," Gradinger said, adding the patient was recovering well.

A team of British scientists using cellular implants has restored sight in adult mice -- possibly paving the way for similar techniques in the treatment of some forms of human blindness. Robert MacLaren, Rachael Pearson and their colleagues from the Institute of Ophthalmology, University College London, plucked retinal cells from newborn mice and transplanted them into adult mice with impaired vision.

Thin sheets of cheek tissue can be used to replace the damaged corneas of people blinded by certain eye diseases, Japanese researchers have reported. Their findings, published in the Sept. 16 issue of the New England Journal of Medicine, may offer new routes to restoring damaged vision and perhaps also for engineering other types of grow-your-own tissue transplants.

The firm's bankruptcy filing Thursday came two weeks after rival Organogenesis Inc. of Boston sought bankruptcy protection from its creditors.
