Model for developmental signaling requirements for touch dome Merkel cell production
The touch dome (TD) is a specialized epidermal sensory structure composed of K8+ Merkel cells (MCs).
Graphical representation of the sequential signaling mechanisms that drive TD MC specification in embryonic mouse skin. TD MC specification requires mesenchymal Wnt signaling which allows Eda signaling to Edar in the developing primary hair placodes and subsequent Shh signaling from the primary hair placodes/germs to adjacent ectoderm containing the TD anlages. Square cells, surface ectoderm. Trapezoidal cells, hair placode/germ cells. Oval cells, periderm.
