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. The regenerative cell extraction unit includes: a main container which is rotated by a torque applied from an external source; a hollow first discharge pipe which is inserted into the main container; and a suction device which is connected to the first discharge pipe; and a plurality of protruding housing portions which bulge outwards along a radius direction with respect to a center of rotation of the main container to accommodate relatively heavy components among components separated from the substance.
