Abstract

Claims (22)

1. A biological composition suitable for implantation or grafting to a human patient comprising:

a mixture of mechanically selected biologic material derived from bone marrow from cut vertebral bodies including cortical and cancellous bone of a human cadaver donor having non expanded whole cells and non-whole cellular components including each of vesicular components and active and inactive components of biological activity, cell fragments, cellular excretions, and extracellular components wherein the mixture is cleaned and packed for processing in a cold media of DMEM without L-glutamine or HEPES; and

wherein the mixture further comprises a protectant or cryoprotectant of polyampholyte to form a coating on the mixture including the non-whole cellular components of the mixture prior to cryopreservation to create a polyampholyte coated mixture, the coated mixture when prepared for implantation by thawing is compatible with biologic function and configured to be implanted with or without a bone particle mixture either within the mixture or separate.

2. The biological composition of claim 1 further comprises bone particles, the bone particles being added to the mixture derived from bone marrow.

3. The biological composition of claim 2 wherein the bone particles include cortical bone particles.

4. The biological composition of claim 2 wherein the bone particles include cancellous bone particles.

5. The biological composition of claim 2 wherein the bone particles include a mixture of both cortical bone particles and cancellous bone particles.

6. The biological composition of claim 2 wherein the bone particles are demineralized.

7. The biological composition of claim 2 wherein the bone particles are mineralized.

8. The biological composition of claim 2 wherein the bone particles include a mixture of mineralized and demineralized bone particles.

9. The biological composition of claim 2 wherein the bone particles have a particle size from 100-300 μm.

10. The biological composition of claim 3 wherein the cortical bone is 2.0 cc of demineralized bone.

11. The biological composition of claim 4 wherein the cancellous bone is 1.5 cc of mineralized cancellous bone.

12. The biological composition of claim 4 wherein the cortical bone is 1.5 cc of mineralized cortical bone.

13. The biological composition of claim 8 wherein the bone particles form a bone mixture of 1.5 cc mineralized cancellous bone, 1.5 cc of mineralized cortical bone and 2.0 cc of demineralized cortical bone.

14. The biological composition of claim 1 wherein the combination of non-whole cell components with a select number of the non-expanded cells sustains pluripotency in the cells.

15. The biological composition of claim 1 wherein the select number of the non-expanded cells includes differentiated committed cells and non-differentiated and non-committed cells.

16. The biological composition of claim 1 wherein the biological composition is predisposed to demonstrate or support elaboration of active volume or spatial geometry consistent in morphology with that of endogenous bone.

17. The biological composition of claim 1 wherein the biological composition extends regenerative resonance that compliments or mimics tissue complexity.

18. The biological composition of claim 17 wherein the regenerative resonance occurs in the presence or absence of a refractory response.

19. The biological composition of claim 1 wherein the protectant or cryoprotectant creates a physical or electrical or chemical gradient or combination thereof for tissue regeneration.

20. The biological composition of claim 19 wherein the gradient has a physical characteristic of modulus or topography.
