Noninvasive Monitoring of Allogeneic Stem Cell Delivery with Dual-Modality Imaging-Visible Microcapsules in a Rabbit Model of Peripheral Arterial Disease

In vitro MSC viability assessment after encapsulation. (a, b) Photomicrographs of unlabeled microcapsules (a) and PFOBCaps (b) containing rabbit MSCs where live cells were stained green and dead cells were stained red. (c) Quantitative MSC viability in unlabeled (open bars) and PFOBCaps (black bars) at 0, 1, 7, and 28 days after encapsulation. The viability of encapsulated MSCs in both microcapsules did not differ significantly.
