The 15 April
2005 issue of Science on page 364-365, vol. 308, has an article
by Nicholas Harden of Simon Fraser University, Burnaby, BC,
Canada; email: firstname.lastname@example.org, “Of Grainy Heads and Broken
Skins.” This describes the latest advances in epidermis repair
as vital to survival of all animals. It views the insect
integument as a barrier to microbe invasion and describes the
signaling pathways that regulate repair of damaged integument.
He makes the point that the repair process in mice and insects
use similar mechanisms; another example of conservation of
genetic function across Phyla.
