Type of repair where damaged cells are repaired by the same type of cell?

Type of repair where damaged cells are repaired by the same type of cell?

• A. Reconstitution
• B. Replacement
• C. Regeneration
• D. Remodeling

Answer: (A)

When tissue heals by using the same type of cells to fill in the damaged area, the process is called reconstitution. This means the resident cells of the tissue proliferate and repopulate the area with cells that have the same characteristics as the original ones, so the tissue can restore its normal structure and function as closely as possible. This approach relies on the tissue’s innate ability to regenerate with its own cell type, provided the surrounding environment supports such restoration. Replacement, by contrast, involves filling the gap with a different type of tissue, often leading to scar formation and a loss of the original tissue’s specific function. Remodeling is about reorganizing the existing tissue’s extracellular matrix and architecture rather than restoring the exact cell population. Regeneration can imply regrowth of tissue, but reconstitution specifically captures the idea of repairing damage using the same cell type to recreate the original tissue.
