What type of cell has up to 50 nuclei and a ruffled border?

The type of cell that has up to 50 nuclei and a ruffled border is an osteoclast. Osteoclasts are large multinucleated cells involved in the resorption of bone tissue. The ruffled border increases the surface area for the secretion of acids and enzymes that break down bone, facilitating the remodeling process.
