In cherubism, the radiolucent, multilocular ('soap bubble') appearance on radiographs is produced primarily by the activity of which cell type?

Cherubism is a fibro-osseous lesion of the jaws driven by numerous osteoclast-like multinucleated giant cells, which resorb bone and create the classic bilateral, multilocular radiolucent ('soap bubble') pattern, typically in the posterior mandible of children, often regressing after puberty.
