Specifically, the ecological niche modeling enables us to identify the species-specific suitable areas through connecting the niche requirements and distribution, which indirectly includes the effects of habitat loss and degradation.
It is possible that CD138+ cells and MSP1-specific ASC in blood may not be only plasmablasts migrating from lymphoid organ to bone marrow [16], [39], [44], but may also represent PC lost from bone marrow through ablation of the niche, or displaced through competition for the niche by new plasmablasts developing from memory B cells.
Environment-mediated drug resistance is a transient state whereby LSCs are under protection through signals from the niche, leading to selections of secondary genetic changes with growth of cells acquiring pharmacologic resistance.
The Bump team is now looking to add a short registration process and tutorial that will offer detailed instructions and walk users through how to optimize the niche features that will be arriving later this year.
Left alone these cells would outcompete the other cells of the niche through their increased division rate from the self antigen, Figure 2C. Figure 2C represents a scenario in a sterile environment where there is no passive attrition to suppress the initial growth of the autoreactive cell.
The composition of the ECM provides full support to the niche through its physical and structural properties.
To receive these extrinsic signals, GSCs remain physically attached to the niche through adherens junctions (Song et al. 2002).
Stem cells must be anchored to the niche through cell-to-cell interactions so they will stay both close to niche factors that specify self-renewal and far from differentiation stimuli.
Another interesting question is the relationship between birdsong and habitat: did these two species' songs evolve so they each travel most effectively through the particular niche that the singers live in?
