Mice skin explants from WT or Slug-deficient mice (−/−)

	WT	WT EGF	−/−	−/− EGF
No. of explants	12	12	12	12
No. of explants displaying ex vivo keratinocyte reepithelialization	11	9	0	0

Explants were maintained ex vivo to allow keratinocyte reepithelialization with or without added EGF, and 12 explants were used for each mouse. Migrating keratinocytes were identified by keratin immunolocalization (see Figure 3). Experiment was repeated four times with similar results.
