BMP-Dependent Modulation of ROS Generation and Scavenging Controls Interdigital Cell Death. [PDF]

open access: yesDev Growth Differ
BMP signaling regulates ROS generation and scavenging to control interdigital cell death in the developing chicken limb, highlighting a balance between oxidative stress and tissue regression. ABSTRACT Programmed cell death during embryonic development plays a vital role in shaping limb morphology in amniotes.

Expression analysis of genes including Zfhx4 in mice and zebrafish reveals a temporospatial conserved molecular basis underlying craniofacial development. [PDF]

open access: yesDev Dyn
Abstract Background Embryonic craniofacial development involves several cellular and molecular events that are evolutionarily conserved among vertebrates. Vertebrate models such as mice and zebrafish have been used to investigate the molecular and cellular etiologies underlying human craniofacial disorders, including orofacial clefts.
