FIG. 7.

Expansion potential of epidermal keratinocyte progenitors generated using defined, standardized substrates. (A) K14+/p63+ cell populations at day 28 of differentiation were subcultured onto the same substrate (gelatin or Synthemax) on which the cells were generated and measurements of cell counts were taken until senescence was observed. (B) Flow cytometry data taken of populations after senescence to confirm the cell populations remained enriched with K14+ cells compared to an isotype control.
