The fundamental concepts and scientific approaches focused on replacing, engineering, or regenerating human cells, tissues, or organs to restore or establish normal function.
Context
These principles operate at the intersection of biology, medicine, and engineering, leveraging stem cell biology, tissue engineering, and biomaterials to address tissue damage and organ failure.
Significance
Regenerative medicine offers transformative potential for treating a wide range of conditions, including degenerative diseases, traumatic injuries, and organ failure, by harnessing the body’s innate healing capabilities or providing functional replacements.
Mechanism
Core mechanisms involve stimulating endogenous repair processes, transplanting stem cells or progenitor cells to differentiate into needed cell types, and constructing functional tissues or organs using scaffolds and cellular components.
Application
Clinical applications are emerging in areas such as wound healing, cardiovascular repair, neurodegenerative disease treatment, and organ transplantation alternatives, with ongoing research expanding its scope.
Metric
Success is measured by the restoration of tissue or organ function, demonstrated through functional recovery, histological assessment of tissue integration and regeneration, and improvement in clinical outcomes.
Risk
Risks include immune rejection of transplanted cells or tissues, uncontrolled cell proliferation (tumorigenesis), potential for infection, and the ethical considerations surrounding certain regenerative approaches.
