A moving front of osteoblast maturation scales regenerating zebrafish bone

Successful regeneration recovers lost tissues to their original form. Here, we investigate how proliferation of bone-forming osteoblasts is timely regulated to control tissue size during zebrafish scale regeneration. Regeneration of the scale osteoblast tissue proceeds in two phases: an initial osteoblast proliferative expansion followed by hypertrophic growth without cell division. First, we…
