3D cluster in vitro. (a) Prepared 3D clusters. Fibrin gel without cells (I), 3D cluster of HUVEC-only (II), 3D cluster of HUVEC-hAMSC (III), and 3D cluster of HUVEC-BMMSC (IV); (b) 3D clusters after culturing 3 days in α-MEM. Fibrin gel without cells (I), 3D cluster of HUVEC-only (II), 3D cluster of HUVEC-hAMSC (III), and 3D cluster of HUVEC-BMMSC (IV). (c) Max diameter of cell clusters. This experiment was repeated three times and a representative sample was shown.
