背景信息

GDF7 (Growth Differentiation Factor 7), also known as BMP12 (Bone Morphogenetic Protein 12), is a member of the transforming growth factor-beta (TGF-β) superfamily. It was initially identified in the 1990s through molecular cloning techniques aimed at discovering novel signaling molecules involved in embryonic development and tissue patterning. Structurally, GDF7 shares conserved features with other TGF-β family proteins, including a characteristic cysteine knot motif critical for receptor binding and signaling.

Functionally, GDF7 plays a key role in regulating dorsal-ventral patterning during central nervous system development, particularly in the formation of dorsal neural tube structures and differentiation of sensory neurons. Studies in animal models have highlighted its importance in embryonic development, where it influences axon guidance and the specification of dorsal interneurons. Beyond neural development, GDF7 is implicated in skeletal and joint morphogenesis, suggesting roles in cartilage and bone differentiation. It also exhibits tissue-specific effects in ocular and cardiac development.

Recombinant GDF7 protein is produced using genetic engineering techniques, often expressed in bacterial or mammalian cell systems to ensure proper folding and bioactivity. Researchers utilize this purified protein to study its signaling pathways, receptor interactions (e.g., with ALK3/6 and BMPR2 receptors), and crosstalk with other morphogens like Wnt and Shh. Therapeutically, GDF7 has attracted interest for potential applications in nerve regeneration, osteoarthritis treatment, and repair of connective tissues, though challenges remain in optimizing delivery methods and minimizing off-target effects. Its dual roles in developmental biology and tissue homeostasis make it a compelling subject for both basic research and translational medicine.
