There are also integumentary placodes that are involved with hair follicle development. In human development, during week 4 a series of thickened surface ectodermal patches form in pairs rostro-caudally in the head region. ---- see [[Neurogenic placode]]. placode.txt Last modified: 2024/06/07 02:49by 127.0.0.1
