PP2A in LepR⁺ Mesenchymal Stem Cells Contributes to Embryonic and Postnatal Endochondral Ossification through Runx2 Dephosphorylation

The authors fate mapped the leptin receptor-expressing (LepR+) MSCs in different embryonic and adult extremities using Lepr-cre; tdTomato mice and investigated the underling mechanism using Lepr-cre; Ppp2r1afl/fl mice.
