We can help you find this article by emailing the authors directly. HoxA genes encode for important DNA-binding transcription factors that act during limb development, regulating primarily gene expression and, consequently, morphogenesis and skeletal differentiation.

Herein, we describe limb development in three pleurodirans: Podocnemis unifilis Troschel, 1848, Podocnemis sextuberculata Cornalia, 1849 and Phrynops hilarii (Dumeril and Bibron, 1835), in an effort to contribute to filling this We have developed an upper-level undergraduate laboratory exercise that enables students to replicate a key experiment in developmental biology. In this exercise, students have the opportunity to observe live chick embryos and stain the apical ectodermal ridge Are you sure you want to remove Limb regeneration in the vertebrates. from your list?

Recent developmental studies suggest that the boundary between neural crest- and mesoderm-derived bones may not be consistent throughout evolution. Two major skeletal systems—the endoskeleton and exoskeleton—are recognized in vertebrate evolution. Embryonic Development of the Limb: The skeletons of most vertebrate limbs develop as a series of precartilage primordia in a proximodistal (PD) fashion; the cartilaginous elements destined to be closest to the body form first, followed, successively by structures more and more distant from the body.

Just like arthropod and vertebrate limbs, cuttlefish appendages have a proximal part that co-expresses Extradenticle and Homothorax, and a distal part that These results show that, as in arthropods and vertebrates, Bmp signaling is required for proper dorsal-ventral development in cephalopods.
