Some will think it a romantic gesture, others will find it grisly. But one willing couple in the UK is about to get the chance, thanks to a government-funded project intended to promote awareness of the issues surrounding tissue engineering."It’s for people who want to give a bit of their body to each other,” says Nikki Stott, a jewellery designer at the Royal College of Art in London. She and her colleague Tobie Kerridge are collaborating with Ian Thomspon, a bioengineer at King’s College London.The tricky part is that the lucky couple will have to provide bone cell samples, for which the team will get ethical approval only if both people already need surgery. The most likely scenario is that both will need wisdom teeth pulling, Thompson says.Ring-shaped scaffold: During that procedure, an extra sliver of bone can be sliced from the jaw to yield bone cells. These cells will be grown on a ring-shaped scaffold structure, which will slowly dissolve as the cells colonise it.The rough bone circles will then be given to the designers, who will consult with the couple and shape the bone into customised rings. Each partner will give the other the ring grown from their cells.One possibility is that the rings could be used as wedding bands. “There is nothing in law that states what a wedding ring can or cannot be made of,” says a spokesperson for the Office of National Statistics, the body that enforces the UK’s marriage guidelines.Interested couples can apply through www.biojewelry.co.uk. The team says this is a one-off, and they have no plans to start a commercial venture.
