Meganuclease - mediated integration of two constructs aiming at monitoring the differentiation of hiPS cells
into keratinocytes will be performed.
For the first set of experiments, first author Trond Aasen, Ph.D., a postdoctoral researcher at the Center of Regenerative Medicine in Barcelona, used viral vectors to slip the genes for the master regulators Oct4, Sox2, as well as Klf4 and c - Myc
into keratinocytes cultured from human skin explants.
Starting with procedures other research teams had previously worked out to convert iPSCs
into keratinocytes, Xu's team demonstrated that by carefully controlling the timing of the growth factors the cells received, they could force the iPSCs to generate large numbers of epithelial stem cells.
The scientists found that celecoxib directly increased stem cell differentiation
into keratinocytes — skin cells required for wound healing.

One potential treatment involves injecting the wound with stem cells, which can change
into other cell types, such as skin cells like
keratinocytes, to help with the healing process.
