20210178020 | 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. | 2021-06-17 |

The step of infusing includes exposing the bone particles to a negative pressure or vacuum to draw the supernatant and/or the polyampholyte cryoprotectant into the bone particles, or alternatively, exposing the demineralized whole bone to a positive pressure to drive the supernatant and/or the polyampholyte cryoprotectant into the bone. The resultant method creates an infused bone grafting composition having bone particles taken from whole bone, demineralized or decalcified at least partially and infused with one or more of a supernatant of biologic material or a polyampholyte cryoprotectant or both. | 2021-06-17 |
