Magnetophoresis module and experiments. a) i—PDMS chip mounted on the microscopy slide with the integrated permanent magnet. ii—chip main channel demonstrating the magnetic beads in flow deviated by the nearby permanent magnet. b) microscopy images showing the bead bound cells (CD45 + cells) in the leukocyte outlet and the fluorescent ASCs in the ASC side after treatment in the magnetophoresis chip. c) leukocyte depletion rates using the two tested flow rates in the microfluidic chip. d) total ASC recovery in absolute counts, in the beginning of the process, after stage 1 HDF module; and after stage 2 (magnetophoresis module).
