Abstract
There are several animal models of glucocorticoid-induced osteoporosis (GIOP), but each requires a long time to evaluate drug effects. Zebrafish scales are classified as dermal bone and potentially represent a convenient animal model of GIOP because they rapidly regenerate following their removal. We clarified that dexamethasone-treated regenerating scales showed malformations, decreased size and circularity. Anti-osteoporosis drugs rescued the scale malformation phenotype eight-days following the removal of scales. Hence, the dexamethasone-induced regenerating scale malformation model may be a useful animal model for discovering drugs to treat GIOP.
