Figure 4.

Three-dimensional images of human in vivo stem cell-treated mandible. (A): Histological section with hematoxylin-eosin staining, as a reference. (B–D): Subvolume of the three-dimensional (3D) synchrotron radiation-based holotomography reconstruction. To improve visualizations, in each 3D image all phases were deleted virtually, except for bone and vessels (B), bone (C), and vessels (D). Yellow arrowheads indicate portions of vessels to distinguish them from possible artifacts. Scale bars = 250 μm.
