[Research progress in cardiac biological pacemaker created by cell transplantation]

Area of Science:

• Biomedical Engineering
• Regenerative Medicine

Context:

• Cardiac biological pacemakers (CBP) offer a potential alternative to electronic devices.
• Cell transplantation is a primary strategy for CBP development.

Purpose:

• To review the current status and challenges in developing cardiac biological pacemakers (CBP) using cell transplantation.
• To identify key problems hindering clinical application and explore potential solutions.

Summary:

• Cell transplantation, particularly using sinus atrial node cells and stem cells, has shown feasibility for CBP construction.
• Significant challenges remain, including difficulties in amplifying transplanted cardiomyocytes, low success rates, and unstable pacemaker function.
• Gene transfection technology is proposed as a potential solution to address these limitations.

Impact:

• Cell transplantation holds promise for future clinical applications in CBP.
• Addressing current limitations could lead to more effective and stable biological pacemaker solutions.
• Further investigation into cell transplantation and gene modification is warranted.
