Compositions for platelet rich plasma (PRP), depleted in neutrophils, are provided. Generally, these compositions comprise a higher concentration of platelets, lymphocytes and monocytes than whole blood with selective depletion of neutrophils to a concentration of less than about 5000/μl. These compositions may have depressed concentrations of red blood cells and hemoglobin. In some variations, the compositions may be useful to treat damaged connective tissue and/or to slow or stop cardiac apoptosis after a heart attack. The PRP composition may be delivered in conjunction with reperfusion therapy.
