Prosoplasia

-plasia and -trophy
  • Anaplasia (structural differentiation loss within a cell or group of cells).
  • Aplasia (organ or part of organ missing)
  • Desmoplasia (connective tissue growth)
  • Dysplasia (change in cell or tissue phenotype)
  • Hyperplasia (proliferation of cells)
  • Hypoplasia (congenital below-average number of cells, especially when inadequate)
  • Metaplasia (conversion in cell type)
  • Neoplasia (abnormal proliferation)
  • Prosoplasia (development of new cell function)
  • Abiotrophy (loss in vitality of organ or tissue)
  • Atrophy (reduced functionality of an organ, with decrease in the number or volume of cells)
  • Hypertrophy (increase in the volume of cells or tissues)
  • Hypotrophy (decrease in the volume of cells or tissues)
  • 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 presupposed 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]
