Description

Osteoporosis thins bone until it breaks easily, and most treatments slow loss rather than rebuild. Jinjin Ma and co-authors study a protein best known from the ends of chromosomes, called TERT. They ask whether it also drives bone building. The team measured the protein in patient samples and in mice that model the disease.

The protein was lower in weak bone, and low levels went with poor bone growth. Tests showed it switches on a growth pathway, BMP4 and Smad1, that bone-forming cells need. The team then loaded the protein's signal into tiny cell-made packets and added a bone-seeking tag. Given to the mice, the packets gathered in bone and restored much of the lost spongy bone. The authors propose this targeted, cell-free approach as a new way to rebuild bone.
