Researchers may have discovered a cheap, plentiful supply of human transplant cells for the treatment of brain damage after stroke or injury.

Poor retention of transplanted cells is the critical bottleneck of heart regeneration.

They found fat built up around the transplanted cells after four weeks.

The small study's main goal was assessing the safety of the transplanted cells.

The transplanted cells were marked by enhanced green fluorescent protein.

However, therapeutic efficacy may be limited by poor survival and retention of transplanted cells.

Liver cells, for example, did best when the transplanted cells were 28 embryonic days old.

These findings demonstrate that biomaterials may be designed to control bone development from transplanted cells.

However, poor long-term engraftment and survival of transplanted cells have largely precluded effective cell replacement.

Also, the newly- transplanted cells were resistant to the virus.

The transplanted cells differentiated into vascular and sinusoidal endothelial cells, and vascular smooth muscle cells.

Serial MR imaging showed the possible detection of transplanted cells in the early period of transplantation.

Intravital confocal fluorescence imaging tracked the persistence of the transplanted cells over 6-months in living animals.

However, the ability to track the fate and function of transplanted cells with current technologies is limited.

These results suggest that this dual-modal imaging strategy is feasible for non-invasively monitoring transplanted cells in vivo.

TPPU results in a significant increase in the retention of transplanted cells compared with cell treatment alone.
