Corrigendum: Irisin promotes osteoblast proliferation and differentiation via activating the MAP kinase signaling pathways.

In addition, there was a typographical error in the Abstract. " Inhibition of p38 MAPK by SB023580 or pERK by U0126 abolished the proliferation and up-regulatory effects of irisin on Runx 2 expression and ALP activity. " now reads " Inhibition of p38 MAPK by SB203580 or pERK by U0126 abolished the proliferation and up-regulatory effects of irisin on Runx 2 expression and ALP activity. " These errors have now been corrected in the PDF and HTML versions of the Article. This work is licensed under a Creative Commons Attribution 4.0 International License.
