By targeting the USAG-1 gene, researchers believe that they can help people without a full set of teeth regrow teeth. The team says that humans have a third set of teeth available as buds, ready ...
The inner ear sensory epithelium is highly conserved among vertebrates, which gives hope that animal models, especially mammal models such as mice, are very applicable to clinical use in humans. [33] The development of human therapies require research in human mammalian cells, perhaps inner ear epithelial organoids .

A person's baby teeth are known to contain stem cells that can be used for regeneration of the dental pulp after a root canal treatment or injury. These cells can also be used to repair damage from periodontitis, an advanced form of gum disease that causes bone loss and severe gum recession.
Early loss of young immature permanent teeth can be detrimental, leading to loss of function and interference of phonetics. Maxillary and mandibular bone development may be altered, especially when the patient is still growing. Psychosocial health of young patient can be severely impacted.
It has been estimated that the average shark loses about 30,000 to 40,000 teeth in a lifetime. Leopard sharks routinely replace their teeth every 9–12 days and this is an example of physiological regeneration. This can occur because shark teeth are not attached to a bone, but instead are developed within a bony cavity. [74]
According to a recent study, baby teeth contain an abundance of stem cells, a very special type of cell that can potentially grow replacement tissue in the body and cure a number of diseases.
This is one of the earliest recorded examples of adult human digit-tip regeneration. [27] Studies in the 1970s showed that children up to the age of 10 or so who lose fingertips in accidents can regrow the tip of the digit within a month provided their wounds are not sealed up with flaps of skin – the de facto treatment in such emergencies.
