Abstract: A display apparatus can include a substrate having a penetrating area and a separating area, the penetrating area including a substrate hole, a first buffer layer having a first-buffer lower layer, and a first-buffer upper layer, a first thin film transistor including a first semiconductor pattern, a first gate electrode, and a first source electrode and a first drain electrode, a first interlayer insulating film; a second interlayer insulating film, an opening extending through the second interlayer insulating film, the first interlayer insulating film, the first gate insulating film and the first-buffer upper layer, and a separation structure in the opening, the separation structure including a first separation layer having a same stacked structure as the first-buffer upper layer, a second separation layer having a same stacked structure as the first gate insulating film, and a third separation layer having a same stacked structure as the first gate electrode.

Abstract: Provided is a regenerative cell extraction system. The regenerative cell extraction system includes: a regenerative cell separation unit which separates fat tissue; and a regenerative cell extraction unit. The regenerative cell separation unit includes: a sub container which is rotated by a torque applied from an external source and includes a space in which fat tissue is housed; a hollow main pipe which is inserted into the sub container; and a pump which is connected to the main pipe. In addition, the regenerative cell extraction unit receives a regenerative cell-containing substance, which is obtained after the fat tissue is centrifuged by the regenerative cell separation unit, from the regenerative cell separation unit, and extracts regenerative cells from the substance by centrifuging the substance.
