Control of osteogenesis by the canonical Wnt and BMP pathways in vivo

Abstract: Although many regulators of skeletogenesis have been functionally characterized, one current challenge is to integrate this information into regulatory networks. Here, we discuss how the canonical Wnt and Smad-dependent BMP pathways interact together and play antagonistic or cooperative roles at different steps of osteogenesis, in the context of the developing vertebrate embryo. Early on, BMP signaling specifies multipotent mesenchymal cells into osteochondroprogenitors. In turn, the function of Wnt signaling … Show more

“…Osteogenesis depends on an ordered sequence of gene activation, starting with bmp2 pathway which usually triggers mRNA runx2 transcription, one of the first factors directing the differentiation of precursor stem cells towards an osteoblastic lineage [51]. We found a sequential activation of both genes in comparison with the 28 years old subjects, whilst basically no significant changes were detected in comparison with 16 years cells.…”

“…The key signaling pathways, via which GFs guide osteogenic cell differentiation, are the TGF-β/BMP- and Wnt-mediated pathways [19,47]. While the BMP pathway ensures differentiation of MSCs into osteo-chondro-progenitors (OCPs), the Wnt pathway is essential for subsequent osteoblastic commitment, i.e., Wnt acts ‘downstream’ of BMP to ensure that OCPs differentiate into osteoblasts and not chondroblasts [47].…”

Genes associated with both TGF-β/BMP and Wnt pathway (Wnt receptors) were upregulated at day 7 [34,35] and day 14 [34] on SLA and SLActive surfaces, suggesting the occurrence of osteogenic differentiation at these time points.…”
