Hh Signaling

Some articles on hh, hh signaling, signaling:

Hedgehog Signaling Pathway - Evolution
... Lancelets, which are primitive chordates, possess only one homologue of Drosophila Hh (figure 7) ... hedgehogs are the most closely related to Drosophila Hh ... Other similarities between the WNT and Hh signaling pathways have been reviewed ...
Compartment (development) - Cell Segregation
... adhesion/affinity is not directly due to en expression, but rather to the ability to receive Hh signaling ... Anterior cells, capable of Hh transduction, will express given adhesive molecules that would differ from those present in posterior cells, creating differential affinity that would prevent them form intermixing ... This signaling-affinity model is supported by experiments that demonstrate the importance of Hh signaling ...
