Biologic composition and method of use
A biologic composition responsive to inflammation has an allograft scaffold matrix for injection or implantation. The allograft scaffold matrix has donor quiescent and/or senescent cells. The donor quiescent and/or senescent cells react in response to signaling of inflammation from host cells or matrix. The reaction to signaling causes the donor quiescent and/or senescent cells to secrete anti-inflammatory cytokines and secrete exosomes to initiate regeneration of the area of the inflammation. The biologic composition further has a cryoprotectant. The cryoprotectant is a polyampholyte, preferably the polyampholyte is an ε-poly-L-lysine. The cryoprotectant is not DMSO or glycerol based. The cryoprotectant is suitable for direct implantation without washing from the allograft scaffold matrix in either a diluted or non-diluted state.

an allograft scaffold matrix in the form of chips, fibers, or particles or combinations thereof configured for injection or implantation, wherein the allograft scaffold matrix is made of bone, cartilage, nucleus pulposus, or dermis material;
wherein the donor quiescent and senescent cells in the cryoprotectant are seeded onto or loaded into the allograft scaffold matrix.

The biologic composition of claim 1 , wherein the allograft scaffold matrix in the form of allograft chips, fibers, or particles or combinations thereof comprises mineralized, demineralized, partially demineralized, or combinations of mineralized and demineralized bone chips, bone fibers or bone particles or any combination thereof.
13 . The biologic composition of claim 1 , wherein the biologic composition reacts to inflammation with a potency and spectral efficiency that exceeds that of a single molecule.
14 . The biologic composition of claim 1 , wherein the donor quiescent and senescent cells of the biologic composition are derived from one or more of germ cell layers including mesoderm, endoderm, or ectoderm or combinations thereof exhibiting a broad range of phenotypes that are lineage agnostic prior to triggering physiologic events.
15 . The biologic composition of claim 1 , wherein the donor senescent cells are from a non-marrow derived source and preferably a spine space.
16 . The biologic composition of claim 1 , wherein the donor quiescent and senescent cells form a heterogenous cell population sufficiently static to remain open to balancing immune response, antigen presentation, cell survival, cell migration, cell differentiation and angiogenesis, such allograft response variable and responsive to broad conditions with multiple separate response to a patient's condition.
17 . The biologic composition of claim 1 , wherein the donor quiescent and senescent cells are responsive to interspinous or any presented biologic challenge.
18 . The biologic composition of claim 1 , wherein the chips, fibers, or particles or combinations thereof of the allograft scaffold matrix are of varied shape to allow the donor quiescent and senescent cells in the cryoprotectant to be interposed between the chips, fibers, or particles.
19 . The biologic composition of claim 1 , wherein the biologic composition is sufficiently stable to protect the anatomy by tissue supplementation while at the same time forming a secretion triggered in the donor quiescent and senescent cells in response to the signal of inflammation.
20 . A method of treating a degenerative condition, comprising:
implanting the biologic composition of claim 1 into a degenerated area exhibiting inflammation;
