What's the difference between prevalence and proliferation?

Prevalence


Definition:

  • (20) These high Danish rates seem to reflect the true prevalence and incidence in the less serious types of progressive muscular dystrophy, probably because the Danish health system with free medical care and easy access to specialized hospital departments makes it possible to identify all cases of progressive muscular dystrophy.

Proliferation


Definition:

  • (n.) The continuous development of cells in tissue formation; cell formation.
  • (n.) The production of numerous zooids by budding, especially when buds arise from other buds in succession.

Example Sentences:

  • (1) The most actively proliferating region of the excurrent duct system is zone 3 of the epididymis, whereas the least active region is the ductuli efferentes.
  • (2) We also show that proliferation of primary amnion cells is not dependent on a high c-fos expression, suggesting that the function of c-fos is more likely to be associated with other cellular functions in the differentiated amnion cell.
  • (3) However, when cross-linked to anti-CD4 or anti-CD8 antibodies a markedly enhanced proliferation of the corresponding subpopulation is observed.
  • (4) Quantitative determinations indicate that the amount of PBG-D mRNA is modulated both by the erythroid nature of the tissue and by cell proliferation, probably at the transcriptional level.
  • (5) In addition to their involvement in thrombosis, activated platelets release growth factors, most notably a platelet-derived growth factor (PDGF) which may be the principal mediator of smooth muscle cell migration from the media into the intima and of smooth muscle cell proliferation in the intima as well as of vasoconstriction.
  • (6) 10D1 mAb induced a substantial proliferation of peripheral blood T cells when cross-linked with goat anti-mouse Ig antibody.
