Comparative study of fetal facial shape between Japanese and North American populations using micro-CT (opens in new tab)

Population-level morphological differences in human cranio-skeletal morphology are reflective of a multitude of genetic, epigenetic, functional and environmental factors. While such differences have been described in postnatal and adult skeletons, how early they originate during cranio-skeletal ontogeny is unknown. Here we compare early human facial morphogenesis utilizing a collection of fetal specimens of Japanese (JP) and North American - European ancestry (NAP). Utilizing 3D micro-CT imag...
