Thalidomide-induced teratogenesis in gray short-tailed opossums (Monodelphis domestica)
… to develop the gray short-tailed opossum (Monodelphis domestica) as a novel mammalian to study thalidomide teratogenesis. In M. domestica we have successfully recreated most morphological defects found in human thalidomide victims. Through RNA sequencing, we have also identified two gene …

Behavior and communication in the short bare-tailed opossum (Monodelphis domestica)
… communication modes were studied in captive <u>Monodelphis domestica</u>, a small solitary, nocturnal, omnivorous marsupial in the family Didelphidae. The social biology was examined to evaluate the importance of visual, olfactory, auditory, and tactile communication. Social contexts were …

The development of the marsupial shoulder girdle: A case study in Monodelphis domestica
… reduction in the gray short-tailed opossum, Monodelphis domestica. Furthermore, it explores the expression patterns and levels of target genes in a comparative study between Monodelphis domestica and Mus musculus. A quantitative morphometric study of shoulder girdle development reveals that …

Limb cell behaviors in Monodelphis domestica growth and development: the effects of Fgf pathway activators and inhibitors
… organ growth, the limbs of the opossum (Monodelphis domestica) to investigate the cellular and molecular basis of differential organ growth in mammals. Opossum limbs are an ideal system with which to study differential growth. Opossum forelimbs grow much faster than hind limbs, resulting …

Disruption of apoptosis and WNT signaling during limb morphogenesis by exogenous retinoic acid: a case study in Monodelphis domestica
… By manipulating forelimb growth in Monodelphis domestica, a novel model system for limb development, this study sheds new light on the mechanisms by which RA disrupts patterning of the AP and PD axes. Based on the results of this study, I propose that RA induces digit reduction by …

Mammalian limb morphology: the role of the crawl in determining marsupial limb integration, development, and evolution
… bone and cartilage growth from three marsupials (Monodelphis domestica, Sminthopsis macroura, Trichosurus vulpecula) and one eutherian (M. musculus). A reflex scope was used to place four points on the stylopod, zeugopod, and autopod and these points were used to determine gross length and width …

The evolutionary transition from reptiles to mammals: analyses of body size reduction and separation of middle ear elements from the jaw
… ear. We utilized micro-CT scans of neonatal Monodelphis domestica taken at five-day intervals throughout the first month and a half of postnatal development to use as comparisons with exceptional fossil specimens from the past 250 million years. Three-dimensional reconstructions from these …
