Tumor‐tropic migration of the living materials and targeted ability of H@C. a) Scheme of the migration process of the living materials. b) Scheme of Transwell construction. c) Magnification profile of both sides of the microporous membrane of the Transwell. d,e) Crystal violet staining and DAPI staining of hADSCs on the underside of the microporous membrane after 12 h of incubation. f) Statistical analysis of the number of migrated hADSCs based on DAPI staining in the 3D Transwell experiment. g) Optical images of the migration state of hADSCs and hADSCs conjugated with 100 µg mL⁻¹ H@C@D for 0, 11, and 24 h. h) Migration rate of hADSCs conjugated with 100 µg mL⁻¹ H@C and H@C@D in the 2D scratch model. i) Attachment of 100 µg mL⁻¹ H@C on the MG63 cell membrane after 2 h. Red, green, and blue indicate Dil‐stained cell membrane, FITC‐labeled H@C, and Hoechst‐stained nuclei.
