MONONUCLEAR-RICH, PLATELET-RICH PLASMA COMPOSITIONS AND METHODS OF USE THEREOF
Compositions for platelet rich plasma (PRP) include a higher concentration of platelets and mononuclear cells than whole blood. Concentrations of lymphocytes, monocytes, and neutrophils can be different from concentrations found in whole blood. The compositions can be delivered at or near a site of tissue damaged by apoptosis, injury, wound, trauma, ischemia, lesion, or degeneration in order to treat the damaged tissue.
1 . A composition comprising:
platelets in a concentration of about 151,000 per microliter to about 7,000,000 per microliter;
mononuclear cells in a concentration about 500 per microliter to about 20,000 per microliter; and
neutrophils in a concentration of about 1 per microliter to about 60,000 per microliter.
2 . The composition of claim 1 , wherein the concentration of platelets is between about 151,000 per microliter to about 5,000,000 per microliter.
3 . The composition of claim 1 , wherein the concentration of platelets is between about 200,000 per microliter to about 2,000,000 per microliter.

6 . The composition of claim 1 , wherein the concentration of mononuclear cells is between about 1,000 per microliter to about 20,000 per microliter.
7 . The composition of claim 1 , wherein the concentration of mononuclear cells is between about 2,000 per microliter to about 20,000 per microliter.
8 . The composition of claim 1 , wherein the concentration of neutrophils is between about 1,000 per microliter to about 10,000 per microliter.
9 . The composition of claim 1 , wherein the concentration of neutrophils is between about 2,000 per microliter to about 5,000 per microliter.
10 . The composition of claim 1 , wherein the concentration of neutrophils is less than about 2,000 per microliter.
11 . The composition of claim 1 , wherein the concentration of neutrophils is less than about 5,000 per microliter.
12 . The composition of claim 1 , wherein the composition further comprises red blood cells in a concentration of about 1 to about 10,000,000 red blood cells per microliter.
13 . The composition of claim 12 , wherein the composition comprises less than about 4,000 red blood cells per microliter.
14 . The composition of claim 12 , wherein the composition comprises less than about 1,000 red blood cells per microliter.
