Brazilian researchers are working to produce stem cells from teeth. The project, being conducted in partnership with a British university, will significantly reduce the cost of stem cell technology.

Scientists at São Paulo State University are building a laboratory to cultivate stem cells from milk teeth.

The project is a partnership between USP's College of Dentistry and King's College, in London.

According to the co-ordinator of the project, Andrea Mantesso, there are stem-cells in the pulp of the 20 milk teeth of each human being. These cells can be used to develop tissue such as bones, muscles, nerves, and even new teeth.

Mantesso said that the main advantage of working with stem cells from teeth is easy access.

He added that research was still in the initial stages and it was impossible to say when will the technique be available for patients. The laboratory starts work next year.

Currently, most stem cells are collected from embryos and the umbilical cords of newborn babies.

The two universities have already collaborated on five other projects.
