Similarities between ontogeny and post-fracture bone regeneration Similitudes entre ontogenia y regeneración ósea post-fractura
(Universidad de la Frontera, 2016)
© 2016, Universidad de la Frontera. All rights reserved.SUMMARY: Bone ossification is a process that occurs during embryogenesis when fetal period begins. It is characterized by a condensation of mesenchymal cells with ...
Developmental evolution of the distal ankle in the dinosaur–bird transition
(Wiley-liss, div John Wiley & Sons Inc., 2020-12)
The adult ankle of early reptiles had five distal tarsal (dt) bones, but in Dinosauria, these were reduced to only two: dt3 and dt4, articulated to metatarsals (mt) mt3 and mt4. Birds have a single distal tarsal ossification ...
Developmental evolution of the distal ankle in the dinosaur-bird transition
(Wiley, 2020)

Bird embryos uncover homology and evolution of the dinosaur ankle
(Nature, 2015)
The anklebone (astragalus) of dinosaurs presents a characteristic upward projection, the 'ascending process' (ASC). The ASC is present in modern birds, but develops a separate ossification centre, and projects from the ...
Macroscopic description of the fetal ossification pattern in alpacas (Vicugna pacos)Descripción macroscópica del patrón de osificación fetal en alpacas (Vicugna pacos)

Mammalian skull heterochrony reveals modular evolution and a link between cranial development and brain size
(Nature Publishing Group, 2014)
Ultrastructure of eggshell and embryological development of Salvator merianae (Squamata: Teiidae)
(Wiley-liss, div John Wiley & Sons Inc., 2020-10-25)
The objective of this study was to characterize the external morphology of Salvator meriane embryos in different stages of embryonic development and establish a relationship with the ultrastructure of the shell from oviductal ...
Skeleton in the closet: hidden diversity in patterns of cranial and postcranial ontogeny in Neotropical direct-developing frogs (Anura: Brachycephaloidea)
(Springer, 2020-10-19)
Direct development implies transformations with respect to the anuran biphasic life cycle, including changes in embryonic anatomy. In the clade Brachycephaloidea, skeletal ontogeny is known inEleutherodactylus coquiof the ...
L-type calcium channels in growth plate chondrocytes participate in endochondral ossification
(2007)
Longitudinal bone growth occurs by a process called endochondral ossification that includes chondrocyte proliferation, differentiation, and apoptosis. Recent studies have suggested a regulatory role for intracellular Ca-2 ...
A cleft lip and palate gene, Irf6, is involved in osteoblast differentiation of craniofacial bone
(2019-03-01)
Background: Interferon regulatory factor 6 (IRF6) plays a critical role in embryonic tissue development, including differentiation of epithelial cells. Besides orofacial clefting due to haploinsufficiency of IRF6, recent ...
