How ageing contributes to bone loss is unclear. In ageing mice, skeletal stem cells lose their ability to generate bone-forming cells called osteoblasts, and instead promote the generation of bone-resorbing cells called osteoclasts.

In stressed cells, proteins and RNA molecules cluster together to form stress granules. It emerges that the small protein modifier ubiquitin is needed to disassemble stress granules in recovering cells.
