Recent progress in tracking the viability of transplanted stem cells in vivo
The viability of the transplanted stem cells is particularly crucial in determining the success of stem cell-based regenerative medicine. Therefore, the development of non-invasive imaging methods that can in situ monitor the viability of the transplanted stem cells is urgently needed. Now, researchers in Su'zhou summarize the recent progress in tracking the viability of the transplanted stem cells in vivo, including reporter-gene based methods, exogenous contrast label-based methods and multimodel imaging methods.

On-chip pumps achieve high-speed sorting of large cells
Nagoya University research developed a high-speed cell sorting method of large cells with high-viability using dual on-chip pumps. The microfluidic chip has three-branched microchannels. Target cells are sorted into one of two interest channels by the high-speed flow produced by the on-chip pumps, while non-target cells enter a waste channel without pump actuation. The technique overcomes the limitation of many on-chip cell sorting methods in achieving the sorting of large cells at a high throughput. (2017-07-28)
