Article Figures & Data
Figures
- FIGURE 1.
(A and B) 18F-FDG uptake kinetics in MSCs and MAPCs: data corrected for radioactive decay (A) and uncorrected data (B). (C) Cellular retention of incorporated 18F-FDG within 180 min.
- FIGURE 2.
Adipogenic, osteogenic, and chondrogenic differentiations of MSCs labeled with 18F-FDG. (A) Extraction of Oil red O dye after adipogenic differentiation measured at 490 nm. (B) Extraction of Alizarin red S (Sigma-Aldrich) dye from differentiated osteoblasts, measured at 560 nm. (C) Extraction of Alcian Blue (Sigma-Aldrich) dye from differentiated chondrocytes, measured at 595 nm. **P < 0.01.
- FIGURE 3.
Quantitative data from TEM of MSCs (A) and MAPCs (B). For both cell types, the following different parameters were assessed: number of lysosomes per cell, average lysosome size, number of vacuoles per cell, average rER width, and average mitochondrial size.
- FIGURE 4.
Small-animal PET data of injected MSCs (A–B) and MAPCs (C–D) labeled with 18F-FDG. Dynamic data from lungs and bladder suggest in vivo elution of 18F-FDG from cells for both cell types. Brain dynamic data were included as control for free 18F-FDG uptake (n = 500,000).
