From: Coaxial 3D bioprinting of self-assembled multicellular heterogeneous tumor fibers
HE and Masson stainings. (A–C) The coaxial 3D bioprinted tumor fiber within the alginate shell; (D) Cells mixed into alginate and cultured for 7 days; E-G: HE staining of the tumor fiber after removal of the alginate shell; H: Cells mixed into alginate and cultured for 21 days. (I–L) Masson staining of the tumor fiber; (M,N) Masson staining of the cells mixed into alginate; (O,P) Masson staining of the GBM tissues. Scale bars: (A,B,E,F,I,M and O) 100 μm; (C,D,G,H,J–L, N and P) 50 μm.
