Regeneration of spinal discs
Compositions and processes for the effective and efficient regeneration of spinal discs are provided. These compositions contain stem cells, donor cells, and platelet plasma compositions. By using these compositions, there is an increased likelihood of acceptance and proper cell differentiation.
1. A process for creating a composition for disc regeneration, said process comprising:
(a) morselizing donor disc material, wherein the donor disc material comprises healthy cells obtained from a non-degenerative level of a spine of a person in need of disc regeneration;
(b) extruding the donor disc material to form an extruded material that comprises chondrocytes and an extracellular matrix;
(c) sequestering platelets from whole blood or bone marrow in order to obtain platelet rich plasma;
(d) extracting and concentrating the platelets from the platelet rich plasma into a platelet lysate through a cell membrane lysis procedure that uses at least one of thrombin and calcium chloride; and
(e) mixing the chondrocytes, the extracellular matrix, a bone marrow aspirate from the person, and the platelet lysate, wherein the bone marrow aspirate comprises stem cells, to form a composition for disc regeneration wherein the composition for disc regeneration is a mixture, wherein the mixture comprises growth factors and within the mixture there is socialization between the chondrocytes and the stem cells due to cell-to-cell signaling, thereby initiating differentiation of the stem cells into chondrocytes.
2. The process according to claim 1 , wherein the bone marrow aspirate comprises red blood cells.
3. The process according to claim 1 , wherein step (e) further comprises mixing thrombin and calcium chloride with the chondrocytes, the extracellular, the bone marrow aspirate and the platelet lysate.
4. The process according to claim 1 , further comprising photoactivating the stem cells.
5. The process according to claim 1 further comprising combining the composition for disc regeneration with a biologic scaffold, wherein the biologic scaffold comprises at least one substance selected from the group consisting of platelet poor plasma, hyaluronic acid, fibrin glue and a flowable wound matrix.
