A Potential Role for MMPs during the Formation of Non-Neurogenic Placodes

open access: yesJournal of Developmental Biology, 2018
The formation of non-neurogenic placodes is critical prior to the development of several epithelial derivatives (e.g., feathers, teeth, etc.) and their development frequently involves morphogenetic proteins (or morphogens).
