The purpose of the present invention is to provide: detergent-free decellularization method of xenogenic biological tissues for human body surgery, in which the pericardium, blood vessels, other membrane-like biological tissues, and the like are decellularized so as to have resistance to mechanical property loss, mineralization and immune reactivity; and decellularized tissue. Decellularized tissue, according to the present invention, when compared to untreated tissue, has greater calcification reduction in vivo, blood compatibility and biocompatibility improvement, tissue thickness reduction, and increases in tensile strength, kink resistance and the like.

The instant disclosure is directed to a method for vascularizing a pancreatic islet comprising culturing the pancreatic islet or β-cells with an endothelial cell comprising an exogenous nucleic acid encoding an ETV2 transcription factor under conditions wherein the endothelial cell expresses the ETV2 transcription factor. The instant disclosure is further directed to a method for making a vascularized β-cell organoid comprising culturing the pancreatic islet or β-cells with an endothelial cell comprising an exogenous nucleic acid encoding an ETV2 transcription factor under conditions wherein the endothelial cell expresses the ETV2 transcription factor. Disclosed also are vascularized islets and vascularized β-cell organoids produced by the methods of the instant disclosure, as well as methods for using the same.

Disclosed herein are methods for introducing functional mitochondria into liver cells in living animals (e.g., mammals). The disclosed compositions and methods can be used to treat clinical conditions characterized by genetic or acquired mitochondrial defects and the resulting dysfunctions and diseases therefrom.
