Dr. John DeSesso, Principal Scientist in Ä¢¹½tv's Health Sciences practice, recently published a paper (co-authored by Dr. Anthony Scialli), which discusses the importance of distinguishing adverse skeletal outcomes from minor ossification delays and presents the chronologic embryology of the rodent, rabbit, and primate skeletons to assist in interpretation of skeletal findings.
Abstract
Evaluation of the skeleton in laboratory animals is a standard component of developmental toxicology testing. Because the skeleton is undergoing developmental changes at the time fetuses are evaluated, transient delays in development can result in what appears to be findings of abnormal skeletal structure such as alterations in the number, shape, and size of ossification centers, and alterations in the numbers of ribs and vertebrae. Determination of whether such findings are permanent changes with adverse consequences is important in study interpretation.
