Treatment composition comprising physically disrupted tooth pulp and non-cultured stem cells
View Patent ↗A medical implant comprising in components from a tooth and stem cells harvested from at least one tooth. Tooth stem cells may be harvested from the dental pulp of mammalian teeth, such as unerupted third molars in humans. After the stem cells are removed and isolated from the other teeth tissue, the hard tooth may be ground into a base material for the manufacture of a porous matrix into which the tooth stem cells can be added. Additionally, soft tissue from the harvested tooth may be used as a carrier scaffold for soft tissue applications such as meniscal or cartilage repair.
1. A medical treatment composition comprising physically disrupted tooth pulp including a plurality of non-cultured stem cells, wherein the composition is in a form for injection or depot.
2. The medical treatment composition of claim 1 , wherein the physically disrupted tooth pulp is chosen from a diced tooth pulp, a minced tooth pulp, and combinations thereof.
3. The medical treatment composition of claim 1 , wherein the physically disrupted tooth pulp is a sterilized, physically disrupted tooth pulp, and wherein the sterilized, physically disrupted tooth pulp includes a plurality of stem cells that are living.
4. The medical treatment composition of claim 1 , wherein the physically disrupted tooth pulp including a plurality of stem cells includes:
one or more endogenous growth factors expressed from endogenous genes of cells of the tooth pulp, or
one or more exogenous growth factors.
5. The medical treatment composition of claim 4 , wherein the one or more endogenous or exogenous growth factors are chosen from transforming growth factor beta, insulin like growth factor I, insulin like growth factor II, platelet-derived growth factor, fibroblast growth factor, and bone morphogenetic proteins.
6. The medical treatment composition of claim 1 , wherein the plurality of stem cells includes pluripotent stem cells.
7. The medical treatment composition of claim 1 , wherein the physically disrupted tooth pulp is non-enzyme-digested.
8. A medical treatment composition comprising physically disrupted non-enzyme-digested tooth pulp including a plurality of stem cells, wherein the composition is in a form for injection or depot.
9. A medical treatment composition comprising:
(a) physically disrupted tooth pulp including a plurality of non-cultured stem cells, wherein the physically disrupted tooth pulp including a plurality of stem cells includes:

(ii) one or more exogenous growth factors; and
(b) a plurality of ground mammalian tooth particles, wherein at least a portion of the plurality of ground mammalian tooth particles are derived from the same mammalian tooth from which at least a portion of the plurality of stem cells are derived.
10. A medical treatment composition comprising:
(a) physically disrupted tooth pulp including a plurality of non-cultured stem cells, wherein the physically disrupted tooth pulp including a plurality of stem cells includes:
(i) one or more endogenous growth factors expressed from endogenous genes of cells of the tooth pulp, or
(ii) one or more exogenous growth factors; and
(b) a plurality of ground mammalian tooth particles, wherein at least a portion of the plurality of ground mammalian tooth particles are derived from a different mammalian tooth from which at least a portion of the plurality of stem cells are derived.
11. A medical treatment composition comprising physically disrupted tooth pulp including a plurality of non-cultured stem cells, wherein the composition is in a form for topical application.
