For instance, irrigation schemes may expand the habitat of disease vectors thriving in and around water bodies [ 9], while the application of agrochemicals may result in a proliferation of populations of problematic primary consumers, such as mosquito larvae or vector snails in wetlands [ 10].
We then assessed whether test-retest variability and accuracy for determination of proliferation of the population input functions were affected by this reduced sampling population-based methodology.
Autoantibody levels are detectable as early as 6 weeks and a pronounced lymphoadenopathy is observed at 12 weeks that is largely due to the proliferation of a population of B220+, TCRβ+, CD3+ cells that are mostly CD4− and CD8−.
This model postulates that cancer originates from mutations occurring in a few cells or a single cell that eventually leads to uncontrolled and unlimited proliferation of a population of cells [ 25].
Prior to monitoring for GUS reporter activity, an alamarBlue assay (30) was carried out in order to provide a simple measure of cell proliferation; as stumpy formation is associated with cell cycle arrest (15), it was expected that any compound causing differentiation would also cause a decrease in proliferation of the population (data not shown).
This potentially promotes the emergence of zoonoses in three ways: directly through the proliferation of host populations, indirectly through the proliferation of vector populations feeding on these hosts, and by increasing the likelihood of encounters between wildlife and domestic animals or humans.
Previous studies have implicated TGFβ signaling in suppressing proliferation of luminal populations and maintaining the potency of basal stem cell populations [ 34, 36, 60].
Fibroblast numbers can be maintained or expanded by proliferation of resident populations but in addition, recent evidence indicates they can also be derived through epithelial-mesenchymal transition or from circulating and tissue-derived mesenchymal stem cells.
Removal of DKK1 from DKK1-involuted mice results in full recovery, suggesting that canonical Wnt signaling is required for the differentiation or proliferation of TEC populations needed for maintenance of properly organized adult thymic epithelial microenvironments.
In this study, we first examined the effect of heat-inactivation of autologous human serum and FBS on proliferation of both populations of MSCs.
