An early event in skeletal joint development is the specification of articular chondrocytes at the joint surface. Articular chondrocytes are distinct in producing lower levels of cartilage matrix and not being replaced by bone, yet how they acquire these properties remains poorly understood. Here, we show that two members of the Iroquois transcriptional(More)
The clinical need for methods to repair and regenerate large cartilage and bone lesions persists. One way to make new headway is to study skeletal regeneration when it occurs naturally. Cartilage repair is typically slow and incomplete. However, an exception to this observation can be found in the costal cartilages, where complete repair has been reported(More)
Polarized epithelia define boundaries, spaces, and cavities within organisms. Cavitation, a process by which multicellular hollow balls or tubes are produced, is typically associated with the formation of organized epithelia. In order for these epithelial layers to form, cells must ultimately establish a distinct apical-basal polarity. Atypical PKCs have(More)
