  • Embryonic skin was cultured with BSA (control) (250 ng/ml), HBEGF (250 ng/ml) or KGF (250 ng/ml) for 24 hours and genomic transcript expression was profiled by microarray. Multiple genes involved in normal interfollicular keratinocyte differentiation and barrier formation are upregulated following HBEGF or KGF treatment. 0, baseline levels or no change; numbers, fold of baseline.
