Prosoplasia

-plasia and -trophy
Anaplasia (structural differentiation loss within a cell or group of cells) Aplasia (organ or part of organ missing) Hypoplasia (congenital below-average number of cells, especially when inadequate) Hyperplasia (proliferation of cells) Neoplasia (abnormal proliferation) Dysplasia (change in cell or tissue phenotype) Metaplasia (conversion in cell type) Prosoplasia (development of new cell function) Desmoplasia (connective tissue growth)
Atrophy (reduced functionality of an organ, with decrease in the number or volume of cells) Hypertrophy (increase in the volume of cells) Dystrophy (any degenerative disorder resulting from improper or faulty nutrition)

Prosoplasia (from Ancient Greek: προσωπον prósopon , "face" + πλάσις plasis, "formation") is the differentiation of cells either to a higher function or to a higher level of organization.^[1]

Assuming an increasing cellular peculiarity from a presuppossed stem-cell fate, prosoplasia is therefore a forward differentiation, unlike anaplasia (a backward differentiation). Examples of prosoplasia include the forward differentiation of cells in the mucosa in Warthin's tumor.^[2]
