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.

Abstract: Methods are described for using compositions containing platelet-rich plasma for the treatment of a variety of tissue lesions, and the use of compositions containing platelet-rich plasma to accelerate or complete the differentiation of a cell line. Particularly, use of platelet-rich plasma in conjunction with cell differentiation.

Abstract: Methods of preparing platelet-rich plasma (PRP) compositions are disclosed which include adding CD34+ cells to the PRP composition. In addition, the concentration of stromal-derived factor-1 (SDF-1) in the PRP composition may be adjusted to a pre-determined value. The compositions may have elevated levels of white blood cells but reduced levels of neutrophils. Compositions produced by the method are also disclosed.

Abstract: Methods are described for using compositions containing platelet-rich plasma for the treatment of a variety of tissue lesions. Particularly, delivery of platelet-rich plasma to bone tissue particularly a vertebral body or in combination with a bone graft are disclosed.

Abstract: Methods are described for using compositions containing platelet-rich plasma for the treatment of a variety of tissue lesions. Particularly, delivery of platelet-rich plasma to tissue such as disc material, a vertebral body, spinal cord, or spinal tendon is disclosed.

Abstract: A particle/cell separation device is described which is particularly adapted for neutrophil depletion from a preparation of whole blood or platelet-rich plasma. Also described are blood and platelet rich plasma compositions produced using the device which are neutrophil-depleted.

Abstract: Compositions which include platelet-rich plasma and fibroblast cells are disclosed for the treatment of skin. In particular, administration of platelet-rich plasma in a dermatologically acceptable carrier repeatedly to skin is disclosed to reduce the appearance of wrinkles.

Abstract: A device to prepare and deliver a bioactive substance such as stem cells, platelet rich plasma, and/or other bioactive compositions. The device can utilize a hallow interior or cavity to deliver bioactive substances during a surgical procedure or to an area of cartilage defect or cartilage disorder. The treated tissues can include connective tissue, cardiac muscle or tissue, spinal tissue, internal organs, skin tissue, brain tissue, vascular tissue, ocular, ear, nose, throat tissue, and/or other hematologic, endocrine or integumentary tissue.

Abstract: A method of increasing differentiation of a cell line of glioblastoma cells is disclosed. A platelet-rich plasma (PRP) composition is prepared. The glioblastoma cells are cultured in the PRP composition for a time period sufficient for differentiation of the glioblastoma cells.

Abstract: A blood component such as platelets is concentrated. The concentrate, such as platelet-rich plasma, is used in a cell culture medium to grow and proliferate cells. The cells may be from the same person from which the blood concentrate is obtained. The cells grown in the culture medium may be used to treat a patient which may be the same patient from which the blood was extracted and/or the cells were obtained.

Abstract: Methods are disclosed to promote vascularization of tissue in mammals using an autologous platelet-rich plasma composition. In particular, a method of treating a cardiac tissue lesion is disclosed.

Abstract: Methods are described for using compositions containing platelet-rich plasma for the treatment of acute or chronic dysfunction of cardiac muscle. The method may employ a kit which includes a platelet-rich plasma composition and a pH adjusting agent and a catheter or syringe for delivery of the platelet-rich plasma composition to dysfunctional cardiac muscle. The kit may also include a syringe for withdrawing blood from a patient and a centrifuge device means to obtain platelet-rich plasma.

Abstract: Compositions and methods for preparing neutrophil-depleted platelet rich plasma are provided. Generally, these compositions comprise a higher concentration of platelets and depressed concentrations of neutrophils relative to whole blood although white blood cells may be at higher concentrations than whole blood. The concentrations of the platelets and/or the white blood cells may be two to eight times the respective concentrations in whole blood. 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 neutrophil-depleted platelet rich plasma composition may be delivered in conjunction with reperfusion therapy.

Abstract: Platelets are concentrated from the blood of a patient. The platelets are unactivated or are treated by a method such as ultrasound or agitation to obtain platelet releasate. The platelets are formulated into an injectable formulation which is administered to the same patient the platelets were extracted from in order to treat the patient's cancer.
