Effect (mean ± SEM) of iPTH on the LSK cell expression of mRNA of genes known to be up-regulated by Wnt signaling. LSK cells were purified by FACS sorting from the BM of vehicle and iPTH-treated WT mice, TCRβKO mice, TCRβKO mice previously subjected to adoptive transfer of WT or Wnt10b^−/− T cells, and Wnt10b^−/− mice. The Wnt-dependent analyzed genes were the same as shown in Figure 5. n = 6 mice per group. *P < .05 versus the corresponding vehicle-treated group.
