Scientists in Japan have discovered a method to grow teeth from single cells in lab dishes and transplant them into mice.
The method involves the use of primitive cells that are injected into a collagen mold. The cells were taken from the tooth germ – a mass of tissue that has the potential of developing into a tooth. The cells eventually mature into a structure that shares the qualities of teeth, including dentin, enamel, dental pulp, blood vessels, and periodontal ligaments. Once transplanted to a mouse, the teeth grew and developed normally.
This is a significant breakthrough in regenerative therapies and demonstrates the possibilities of developing bioengineered organs to replace organs failing from age, disease, or injury.
Stem Cell research is the source of great controversy and heated debate due to the techniques used to obtain and use them. With current technology, starting a stem …
