Methods are disclosed herein for increasing retinal ganglion cell survival in a subject in need thereof. These methods include selecting a subject in need of increased retinal ganglion cell survival and administering a therapeutically effective amount of isolated nanovesicles derived from an extracellular matrix (MBVs) to the subject.

Methods and compositions are provided for combined transplantation of a solid organ and hematopoietic cells to an HLA mismatched recipient, where tolerance to the graft is established through development of a persistent mixed chimerism. An individual with persistent mixed chimerism, usually for a period of at least six months, is able to withdraw from the use of immunosuppressive drugs after a period of time sufficient to establish tolerance.

The method of tissue transplantation involving recellularizing of a donor organ with the utilization of the recipient's cytokines collected from the recipient's blood plasma at less than systemic pressure, and at the temperature greater than freezing and less than normal systemic temperature of the recipient's blood. Specifically, a method of harvesting a platelet-derived growth factors from platelet rich plasma (PRP), the growth factors having increased weight.

Provided are improved methods for grafting donor derived CDS 4+ cells in an organ transplant recipient comprising administration CD3+ cells together with a calcineurin inhibitor in an effective amount to reduce or prevent an immune system of the recipient from rejecting the CD3+ cells from the donor, thereby enabling the CD3+ cells of the donor to facilitate engraftment of the CDS 4+ cells from the donor. In certain embodiments, the effective amount of the calcineurin inhibitor provided to reduce or prevent the immune system of the recipient from rejecting the CD3+ cells of the donor is lower than an amount provided for protecting the organ of the donor from rejection by the immune system of the recipient.

The present application provides methods of functionalizing an organ or tissue of a mammal by administering a nutrient (e.g., peracetylated N-azido galactosamine Ac4GalNAz) to the mammal or by culturing an organ or tissue in a bioreactor containing such nutrient. The present application also provides methods of selectively functionalizing extracellular matrix (ECM) of an organ or tissue of a mammal by administering a nutrient (e.g., peracetylated N-azido galactosamine Ac4GalNAz) to the mammal. In some aspects, the present application provides a decellularized scaffold of a mammalian organ or tissue comprising an extracellular matrix, wherein the extracellular matrix of the decellularized scaffold is functionalized with a chemical group that is reactive in a bioorthogonal chemical reaction, such as an azide chemical group. The present application also provides biological prosthetic mesh and mammalian organs and tissues for transplantation prepared according to the methods of the application.
