What process involves the replacement of destroyed tissue by the same kind of cells?

Regeneration is the process that involves the replacement of destroyed tissue by the same kind of cells. This biological mechanism allows for the restoration of tissue architecture and function following injury or damage. In regeneration, cells that are lost or damaged are replaced by similar types of cells, leading to a return to normal tissue structure and function. This is typical in tissues that have high regenerative capacity, such as skin, liver, and certain types of epithelial tissues.

The other processes, while related to tissue repair and adaptation, do not involve the direct replacement of the same type of cells. For instance, fibrosis refers to the formation of scar tissue when normal tissue is replaced by connective tissue, often resulting in a loss of function. Metaplasia is the change of one differentiated cell type to another, which is not tissue destruction replacement but rather a transformation in response to chronic irritation or inflammation. Hyperplasia refers to an increase in the number of cells in a tissue or organ, which may occur in response to stimuli but does not describe the restoration of damaged tissue to its original structure.
