Dr Angelova-Volponi and Mr Zhang at work creating tooth cells.
The material allows cells to communicate with one another as they would in the body, enabling them to develop into tooth cells. This was reported in the journal ACS Macro Letters. The material was made from hydrogel — a soft, gel-like material that can absorb large amounts of water — and emulates the environment around the cells in the body, known as the matrix.
Scientists at King's College London have been working on a process for growing teeth from stem cells which interact to signal molecules to trigger tooth formation. The stem cells differentiate into various forms of cells, which then secrete the materials that the tooth is eventually made from, such as enamel, dentin and cementum.
Having created the environment to grow teeth, scientists now must work out how to get them from the lab to a patient's mouth.
