While long distance dispersal of planktotrophic larvae in marine organisms has tradi- tionally been considered the norm, several recent studies have shown that local retention of larvae and hydrodynamic barriers to dispersal often exist. This study f

The formation of scales and feathers in reptiles and birds has fascinated biologists for decades. How might the developmental processes involved in the evolution of the amniote ectoderm be interpreted to shed light on the evolution of integumental ap

The discovery that structurally unique ''filamentous integumentary appendages'' are associated with several different non-avian dinosaurs continues to stimulate the development of models to explain the evolutionary origin of feathers. Taking the phyl

Immunohistochemical studies, supported by additional lines of evidence, suggest that original proteinaceous components of keratin claw sheath material may be preserved in the pedal ungual phalanx associated with the primitive bird, Rahonavis ostromi,

We report small fibrous structures associated with a new specimen of Shuvuuia deserti, which we hypothesize are remnants of feather-like epidermal appendages. Multiple analyses suggest that these structures are epidermally derived and contain epitope

The transient embryonic layers primarily composed of a periderm and subperiderm cover most regions of the chick embryo and are the first suprabasal cell layers covering the body ectoderm. This study presents evidence for regional variation in the exp

The expression of two previously uncharacterized polypeptides produced in epidermal cells of chick reticulate and scutate scales during late embryonic scale histogenesis and in hatchling birds has been studied biochemically and immunologically. These

Rotation-mediated aggregation was used to test the capacity of early embryonic tongue cells from different regions of the tongue to reorganize histotypically and terminally differentiate in vitro. Cells dissociated from the anterior ventral (AV) or p

Using antisera to analyze the expression of specific gene products is a common procedure. However, in multigene families, such as the beta-keratins of the avian integument where strong homology exists among the scale (ScbetaK), claw (ClbetaK), feathe
