The cell’s recycler is a shape shifter that is versatile, subtle and sophisticated

Developing bone in normal (top) and mutant (bottom) embryos. Protrusions in a developing bone are formed by a distinct class of cells (green) that differ from the regular bone-forming cells (yellow-orange). Incorrect regulation and distribution of these cells leads to irregularities in the shape of the forming bone
