The present disclosure relates to the generation of an activated platelet product in which one or more of the presence or absence of clots, the timing of clot formation (if present), and/or the mechanical strength of clots (if present) is controlled by the presence or concentration of calcium ions during the activation process. In certain embodiments, the calcium ion concentration is controlled in the presence of pulsed electric fields or a chemical activator (e.g., thrombin) as part of the activation process.

The present invention concerns platelets transfected with exogenous genetic material and microparticles deriving from said transfected platelets having a high percentage of transfection and able to transport and to transfect acceptor cells with genetic material and then used for example in gene and cell therapy. The invention further concerns a method for the preparation of mature platelets transfected with exogenous genetic material and microparticles deriving from said transfected platelets and microparticles deriving from said transfected mature platelets which permits to obtain high percentages of transfection.

A therapeutic hemoglobin-based oxygen carrier solution is formed by directly combining at least one of freeze-dried platelets and freeze-drug plasma with a hemoglobin-based oxygen carrier. The therapeutic hemoglobin-based oxygen carrier solution can be employed to treat bleeding or anemia and simultaneously increase systemic convective oxygen delivery in a subject suffering low circulatory oxygen transport or bleeding.

The present invention discloses a use of mitochondria to promote wound repair and/or healing. Specifically, when a certain amount of mitochondria or a composition containing a certain amount of mitochondria is administered to a wound, the effect of promoting wound repair or accelerating wound healing can be effectively achieved.

Methods and compositions for the prevention or reduction of platelet transfusion associated complications are provided. The subject methods include modifying donor whole blood or platelets prior to transfusion to prevent or reduce alloimmune platelet refractoriness.

Provided herein are methods for treating coronavirus diseases. In one embodiment, the method comprises administering to a coronavirus disease patient a therapeutic amount of decidua stromal cells. In one embodiment, the method comprises administering to the subject a therapeutic amount of decidua stromal cells (DSCs). In some embodiments, the coronavirus disease is SARS, MERS or COVID-19. The method of the disclosure can be used to treat a subject who has acute respiratory distress syndrome (ARDS), acute lung injury (ALI), or both.
