Fig. 1From: Three-dimensional cultured mesenchymal stem cells enhance repair of ischemic stroke through inhibition of microgliaThree-dimensional (3D) spheroid culture reduced the size of mesenchymal stem cells (MSCs). Two-dimensional (2D) MSCs a and 3D MSCs b were labeled with GFP and DiI, respectively. Photos showed the size of MSCs. c Comparison of the size of 2D and 3D MSCs. d Histogram showed the size of 2D and 3D MSCs with flow cytometry. The apoptosis of 2D MSCs (e) and 3D MSCs (f) were analyzed with annexin V/PI stainingBack to article page
