We studied the influence of doubling the mass of explanted fragments of the dorsal and ventral loach blastoderm at the early gastrula stage on their capacity for differentiation of axial structures. The dorsoventral differences are as follows: the differentiation of somites correlates, according to the results of factor analysis, with the shape complication only in double dorsal explants, while the notochord is more differentiated in the ventral fragments, if it is present, than in the dorsal ones. Doubling of the mass of dorsal fragments of the blastoderm enhances their morphogenetic potencies and shifts differentiation towards the formation of trunk axial structures. The increased mass of ventral fragments does not affect their differentiation and morphogenesis, but disturbs the correlation of these processes.

Farnesoid X receptor (FXR), a nuclear receptor, is expressed in calvaria and bone marrow stromal cells and plays a role in bone homeostasis. However, the mechanism of FXR-activated osteoblast differentiation remains unclear. In this study, we investigated the regulatory mechanism underlying FXR-activated osteoblast differentiation using bone morphogenetic protein-2 (BMP-2)-induced mouse ST-2 mesenchymal stem cells.

BMP-9 and BMP-10 are TGF-β family signaling ligands naturally secreted into blood. They act on endothelial cells and are required for proper development and maintenance of the vasculature. In hereditary hemorrhagic telangiectasia, regulation is disrupted due to mutations in the BMP-9/10 pathway, namely in the type I receptor ALK1 or the co-receptor endoglin.

Bone morphogenetic protein 2 (BMP2) is clinically applied for treating intractable fractures and promoting spinal fusion because of its osteogenic potency. However, adverse effects following the release of supraphysiological doses of BMP2 from collagen carriers are widely reported. Nanoclay gel (NC) is attracting attention as a biomaterial, given the potential for localized efficacy of administered agents.

The current clinical applications of bone morphogenetic proteins (BMPs) are limited to only a few specific indications. Locally controlled delivery of combinations of growth factors can be a promising strategy to improve BMP-based bone repair. However, the success of this approach requires the development of an effective release system and the correct choice of growth factors capable of enhancing BMP activity.
