Biology Induction Research Task Article: Test - Tube Teeth * The article is about if tissue engineers can manufacture living replacement teeth. Scientists have observed how nature engineers a tooth and have combined this understanding with advances in stem cell biology and tissue engineering technology to get closer to and understand biological replacement teeth. The construction of a tooth takes about 14 months to complete in a developing human. Two different types of embryonic tissue combine to produce a tooth, and an ongoing molecular interaction between them leads the process. Tissue engineers are studying these signals and steps to understand the signals they need to replicate as they manufacture living bioengineered replacement teeth. Scientists are connecting stem cells to create the tooth buds that form in the early embryo. The idea is to implant these "primordial teeth" (that are in their early stage) into human jaws and let the cells take...
