Summary of experimental results. Keratinocytes are shown as wild type (WT) or expressing DeltaFl (Fl), DeltaDS (DS) or DeltaVA (VA). <- represents signal from Delta-expressing cell to wild type cell; <-> represents reciprocal signalling between two Delta-expressing cells. The differentiation signal is represented by three types of arrow, the thinnest representing no enhanced differentiation, the thickest representing a strongly increased signal, and the medium arrow differentiation that is slightly enhanced. Intercellular adhesion (cohesion) is shown as being promoted (arrow) or not (cross through arrow).
