**Background of BMP4 Recombinant Protein**
Bone Morphogenetic Protein 4 (BMP4), a member of the transforming growth factor-beta (TGF-β) superfamily, is a secreted signaling protein critical during embryonic development and tissue homeostasis. Initially identified for its role in bone and cartilage formation, BMP4 regulates diverse cellular processes, including cell differentiation, proliferation, and apoptosis. It functions by binding to transmembrane serine/threonine kinase receptors, activating downstream SMAD-dependent and non-SMAD pathways, which modulate gene expression.
Recombinant BMP4 is produced using genetic engineering techniques, often expressed in mammalian (e.g., CHO or HEK293 cells) or bacterial systems. This engineered protein retains the biological activity of native BMP4. enabling its use in research and therapeutic applications. Its applications span stem cell differentiation (e.g., guiding pluripotent stem cells toward mesodermal or ectodermal lineages), tissue engineering (e.g., bone regeneration), and disease modeling (e.g., studying developmental disorders or cancer).
In clinical contexts, BMP4 has shown potential in treating bone defects and degenerative diseases. However, its dual role in cancer—acting as a tumor suppressor in some contexts while promoting metastasis in others—highlights the need for careful study. Quality-controlled batches, verified via SDS-PAGE, Western blot, and bioactivity assays, ensure consistency for experimental or clinical use. Ongoing research aims to optimize delivery systems and mitigate off-target effects, underscoring BMP4’s significance in developmental biology and regenerative medicine.
