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.

Methods are disclosed for treating an acute respiratory distress syndrome, such as an acute respiratory distress syndrome associated with a viral infection, such as SARS-CoV2 (COVID-19) in a subject in need thereof. These methods include administering to the subject a pharmaceutical preparation comprising isolated matrix bound vesicles (MBV) derived from extracellular matrix.

The present invention relates to methods for removing antigens from tissues by sequentially destabilizing and/or depolymerizing cytoskeletal components and removing and/or reducing water-soluble antigens and lipid-soluble antigens. The invention further relates to tissue scaffolding and decellularized extracellular matrix produced by such methods.
