Abstract

Compositions for platelet rich plasma (PRP) and neutrophil-depleted PRP are provided. Methods for treating ischemia damaged tissues by delivering a PRP composition, in some embodiments a neutrophil-depleted PRP composition to the damaged tissue are provided. In some variations, the compositions may be useful to treat ischemic heart disease and repair damaged cardiovascular tissue following acute myocardial infarction including congestive heart failure. In some variations, the compositions may be useful to reduce cardiac apoptosis after a heart attack.

Claims (14)

2 .- 31 . (canceled)

32 . A method of reducing apoptosis in ischemia damaged tissue, comprising:

delivering a platelet rich plasma (PRP) composition without an exogenous activator to a site of ischemic damage;

wherein the PRP composition comprises:

platelets derived from whole blood at a first concentration of at least about 1.1 times a platelet concentration in the whole blood;

white blood cells derived from the whole blood at a second concentration of at least about 1.1 times a white blood cell concentration in the whole blood, wherein the white blood cells comprise:

lymphocytes, wherein the lymphocyte concentration is 1.1 times lymphocyte concentration in the whole blood; and

monocytes, wherein the monocyte concentration is 1.1 times monocyte concentration in the whole blood.

33 . The method of claim 32 , wherein the white blood cells comprise:

neutrophils, wherein the neutrophil concentration is less than the neutrophil concentration in the whole blood

34 . The method of claim 32 , wherein the PRP composition is delivered using a needle or catheter sufficient for injection of the platelet-containing composition.

35 . The method of claim 32 , further comprising preparing the composition from the whole blood of a patient.

36 . The method of claim 32 , further comprising testing a platelet rich plasma for conformance to the composition prior to delivering the composition.
