Prosoplasia

-plasia and -trophy
  • 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: πρόσω prósō, "forward" + πλάσις plasis, "formation") is the differentiation of cells either to a higher function or to a higher level of organization.

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.
