Abstract: A method of generating multipotent stem cells from adult human peripheral blood cells by isolating the peripheral blood insulin-producing cells and exposing them to adult peripheral blood-derived mitochondria. Adult peripheral blood insulin-producing cells (PB-IPC) are isolated from adult peripheral blood by adherence to a hydrophobic surface with a positive charge, such as a Petri dish. Once the PB-IPC are isolated, mitochondria derived from adult peripheral blood are applied to the isolated PB-IPC. The mitochondria are then taken in by the PB-IPC and enter the nuclei of the PB-IPC, allowing the cells to be reprogrammed, transforming PB-IPC into multipotent stem cells and giving rise to three germ layer-derived cells. Additionally, PB-IPC give rise to functional CD34+ hematopoietic stem cell (HSC)-like cells after treatment with adult peripheral blood-derived mitochondria.
