TERT Marks Transitional Growth‐associated SSCs

Skeletal progenitor/stem cells (SSCs) play a critical role in postnatal bone growth and maintenance. Telomerase (Tert) activity prevents cellular senescence and supports the maintenance of stem cells in self‐renewing tissues, and now, researchers led by Diana L. Carlone (Boston Children's Hospital, Boston, MA, USA) report on their investigation of Tert expression in postnatal mouse long bone. In their recent STEM CELLS article, the authors describe the temporally-regulated expression of Tert in SSCs during a discrete phase of transitional growth between rapid bone growth and maintenance.
