BMPs in bone regeneration: Less is more effective, a paradigm-shift

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Orthopedics

Background:

• Bone morphogenetic protein 2 (BMP2) is clinically applied for bone regeneration.
• Difficult bone healing situations often lack simple clinical solutions.
• BMP2 has been known for over 125 years.

Purpose of the Study:

• To review historical aspects and current clinical issues of BMP2.
• To summarize new research findings on BMP2 efficacy and function.
• To explore how BMP2 dose and mechanical loading influence bone regeneration.

Main Methods:

• Literature review of historical data.
• Analysis of current clinical challenges.
• Synthesis of recent research on BMP2 efficacy and function.

Main Results:

• BMP2 has a growing clinical application in bone regeneration.
• Understanding BMP2 dose and mechanical loading interactions can guide future strategies.
• Knowledge gaps exist regarding BMP2's detailed function and signaling pathways.

Conclusions:

• Continued basic research is essential for BMP2.
• Further investigation into BMP2's function and signaling pathways is needed.
• Enhancing BMP2's relevance and safety in clinical practice requires more research.
