Regulatory sequences downstream of a key limb identity gene are required for normal sizes of leg bones, and are changed in wild species with dramatic alterations in pelvic structures.

Quantitative analyses of multi-dimensional microscopy datasets with a new Fiji/ImageJ plugin for cell tracking reveal the lineage restrictions and morphogenetic cellular behaviors underlying embryonic limb outgrowth in the direct developing crustacean Parhyale hawaiensis.

The same genes and signaling pathways control the formation of limbs in vertebrates, arthropods and cuttlefish.

The same genes and signalling pathways control the formation of skin appendages in both fish and land animals.

Type XVII collagen, a transmembranous protein in basal keratinocytes, suppresses interfollicular epidermal proliferation in neonatal and aged skin, and helps rejuvenate epidermis.

Inflammatory cells differentially regulate a scarring versus a regenerating response to injury in mammals.

The neuroanatomical and functional analysis of genetically-identified motoneurons controlling all major steps of Drosophila proboscis extension provides new insights into the architecture of a motor circuitry controlling a reaching-like behavior.

The first malacostracan genome sequence will establish the genetically tractable Parhyale hawaiensis as a model organism in this key animal group.
