Regeneration

These flashcards cover key vocabulary and concepts related to regenerative medicine, including definitions and processes involved in regeneration and repair.

Synesthesia

A rare condition often occurring after a stroke, where sensory signals get crossed due to damage in the sensory neural pathways.

Transient Ischemic Attack (TIA)

An incomplete stroke characterized by total recovery and serves as a warning for severe cerebral pathology and impending major strokes.

Regeneration

The process of replacing injured, diseased, or missing body parts or tissues with structural and functional tissue, resulting in complete restoration of tissue architecture and function.

Repair

The rapid restoration of tissue integrity that does not restore original structure but is characterized by scar tissue formation.

Epimorphosis

A type of regeneration involving blastema-based regeneration where lost structures are regrown anew, restoring the same architecture and function.

Morphallaxis

A regenerative process characterized by limited blastema formation and cell division, relying on cellular plasticity and tissue remodeling.

Compensatory regeneration

Restoration of mass and function without re-establishing the original anatomical structure, occurring without the formation of a blastema.

Stem cell-mediated regeneration

A regenerative process where organisms retain adult specialized cells capable of self-renewal for future injuries.

Determining factors of regeneration vs. repair

Factors include injury severity, tissue type, stem cell availability, inflammatory response, extracellular environment, age, and overall health.

Regenerative Medicine

A field aiming to replace or regenerate human cells, tissues, or organs to restore normal function.

Bio scaffolds

Structures composed of extracellular matrix (ECM) of native healthy tissue, used in regenerative medicine to promote tissue reconstruction.

Multipotency of stem cells

The ability of stem cells to become several or many different cell types in the body, with self-renewing capability.
