Salamander Limb Regeneration Targets Heart Repair

Salamanders regrow entire limbs using blastema cells linked to genes like Pax7. Scientists applied this knowledge to heart tissue repair with promising results. Their 2023 study showed 10% regeneration of damaged heart tissue in zebrafish. Max Planck Institute projects human trials by 2030. This regenerative approach might someday replace pacemakers entirely by restoring the heart’s natural electrical system rather than supplementing it with devices.
