The skeleton of adult zebrafish fins comprises lepidotrichia, which are dermal bones of the rays, and actinotrichia, which are non-mineralized spicules at the distal margin of the appendage. Little is known about the regenerative dynamics of the actinotrichia- specific structural proteins called Actinodins. Here, we used immunofluorescence analysis to determine the contribution of two...

Zebrafish heart regeneration relies on the capacity of cardiomyocytes to proliferate upon injury. To understand the principles of this process after cryoinjury-induced myocardial infarction, we established a spatio-temporal map of mitotic cardiomyocytes and their differentiation dynamics. Immunodetection of phosphohistone H3 and embryonic ventricular heavy chain myosin highlighted two distinct...

In mammals, the loss of a limb is irreversible. By contrast, urodele amphibians and teleost fish are capable of nearly perfect regeneration of lost appendages. This ability depends on direct interaction between the wound epithelium and mesenchymal progenitor cells of the blastema. It has been known for decades that contact between the wound epithelium and the underlying blastema is essential for...
