In man and animals, hyperplasia is based on the intensified reproduction of cells and the formation of new structures. Hyperplasia is observed in various types of pathological growth of tissues (chronic productive inflammation and tumor), in regeneration, and in hypertrophy. Hyperplasia often carries with it compensating characters. In plants, it may be a local growth of tissues resulting from mitotic or amitotic cell division. It occurs with infection by destructive or pathogenic organisms, during trauma, and under the influence of growth stimulants, pesticides, and other preparations. The result of hyperplasia is the formation of galls, calluses, and warts. hyperplasia[‚hī·pər′plā·zhə] (medicine) Increase in cell number causing an increase in the size of a tissue or organ. hyperplasia
