Abstract: Described herein are methods of recellularizing an organ or tissue matrix.

Abstract: The invention described herein provides systems and apparatuses for an initial preparation of an organ or tissue scaffold comprising an extracellular matrix, and subsequent recellularization of the scaffold to ultimately form a resultant artificial organ or tissue incorporating the natural and original extracellular matrix. The techniques and equipment of the invention collectively minimize scaffold collapse, compression or physical damage to the organ as well as afford the advantages of significant maintenance of the initial natural structural and biochemical attributes of the organ or tissue. The invention is particularly useful in organ and tissue transplantation and repair.

Abstract: The present invention relates generally to stem/progenitor cells and, in particular, to therapeutic strategies based on the use of such cells to effect vascular rejuvenation and/or to serve as delivery vehicles.

Abstract: The present invention relates, in general, to Fas Ligand (FasL) and, in particular, to a method of immunoprotecting transplanted cells using an uncleavable form of FasL. The invention also relates to compounds and compositions suitable for use in such a method.
