Abstract: An organic light emitting diode (OLED) display panel and a display device are provided. A retaining wall of the OLED display panel includes a substrate retaining wall layer, an inorganic retaining wall layer, and an organic retaining wall layer stacked on each other. Based on a structure of the retaining wall, a height of the retaining wall is increased, which can better block movements of organic materials and reduce a distance between the retaining wall and a display region. Meanwhile, the undercut shape between the retaining wall and the display region can also increase moving paths of the organic materials, which can further reduce the distance between the retaining wall and the display region, and can prevent cutting cracks from extending to the display region along the inorganic layer and a substrate, which can further reduce frame sizes.

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.
