Biomaterials doped with Bone Morphogenetic Protein 2 (BMP2) have been used as a new therapeutic strategy to heal non-union bone fractures. To overcome side effects resulting from an uncontrollable release of the factor, we propose a new strategy to site-directly immobilize the factor, thus creating materials with improved osteogenic capabilities.

This article describes surface labeling and ex ovo tissue culture in the early chick embryo. Techniques amenable to time-lapse bright field, fluorescence, and optical coherence tomography imaging are presented. Tracking surface labels with high spatiotemporal resolution enables kinematic quantities such as morphogenetic strains (deformations) to be calculated in both two and three dimensions.

A method to create and live-image different humanized bone-marrow niches in mice is presented. Based on the supportive niche created by human mesenchymal cells, the addition of human endothelial cells induces the formation of human vessels, while the addition of rhBMP-2 induces the formation of human-mouse chimeric mature bone tissue.

One constraint of preclinical research in the field of bone repair is the lack of experimental control over the local mechanical environment within a healing bone lesion. We report the design and use of an external fixator for bone repair with the ability to change fixator stiffness in vivo.
FAQs
Binding initiates a receptor-mediated signaling cascade rather than acting directly on DNA. A BMP first engages type I and type II serine/threonine kinase receptors on a target cell. This activates SMAD proteins, which move into the nucleus and change gene expression. The resulting transcriptional response links an extracellular signal to cell fate and tissue formation.
SMAD proteins provide the intracellular connection between BMP receptors and the genome. Once activated, they enter the nucleus, where they alter expression of genes that influence how target cells behave. This step explains how an extracellular signal can produce changes in cell fate, tissue formation, or repair rather than only a surface response.
BMP signaling helps guide mesenchymal stem cell differentiation by changing gene expression through the receptor-SMAD pathway. These cells therefore become important targets when researchers study skeletal development, bone formation, or repair. Understanding this relationship helps connect molecular signaling with the formation of specialized tissues in developmental biology and regenerative medicine.
Their biological effects extend beyond a single skeletal tissue. BMPs help regulate tissue formation and repair, with particular importance for bone and cartilage. This broad relevance allows studies to examine how signaling influences skeletal development, fracture healing, and regenerative strategies, while also supporting research into engineered tissues designed to restore or model these structures.
In tissue engineering, BMPs serve as biological signals that can guide cells toward tissue formation and repair. Biomaterials are being designed to deliver these signals in a controlled manner, rather than presenting them without regulation. Such designs connect molecular signaling with engineered environments intended to support skeletal regeneration and other regenerative medicine goals.
BMP research connects developmental biology, regenerative medicine, and disease investigation. Studies can examine how these signals contribute to skeletal development and fracture healing, while also exploring their relevance to developmental disorders and cancer. This range makes BMPs useful for linking normal regulation of cell fate with abnormal tissue or disease-related processes.
