This patent covers a new type of stem cell derived from the dental pulp, it is useful for entities seeking to generate articial teeth, or dendin/pulp tissue. However, given that the patent actually claims a tooth stem cell, it may also be considered a composition of matter patent (although phenotype is somewhat ill defined in the claims). The patent has 3 independent claims. The first covers a culture of human dental pulp stem cells. The second covers a method of regenerating human dentin/pulp tissue, while the third covers a method of producing the same tissue.

It will be interesting to see if actually the stem cells from the teeth take off to the same capacity as other types of stem cells.
Dr Morales and Dr Steenblock have both told me about the strong potential of these cells. If anyone has more information on this, I am very interested in starting a business based on the storing and expanding of stem cells from the teeth.
The problem is that the current patent seems to only discuss ability of the tooth stem cells to elaborate dendtin and not too much about ability to generate other cells.
I know the there are other cells hoever since numerous papers have shown that stem cells from the tooth are almost the same as mesenchymal stem cells from other parts of the body.
