Through this mechanism, stem cells achieve the production of both self-renewing and differentiating cells in a single cell division.
Through this mechanism stem cells are able to produce all the multiple cell types found in the tissue from which they reside.
Joe Williams Executive Director Democrats for Education Reform New York, Aug. 12, 2008 To the Editor: The current uncritical preoccupation with testing as an education reform mechanism stems from the assumption that test scores provide an accurate bottom line that can be used to account for school performance.
Maintenance of the airway protection mechanism stems from the delicate balance between normal mucus production, transport and clearance.
One such mechanism stems from GPHN being present at inhibitory γ-aminobutyric acid (GABA) synapses where it aids in the translocation and stabilization of GABA receptors to the postsynaptic membrane (reviewed by Sassoe-Pagnetto [ 87]).
Through this mechanism, a stem cell can produce both self-renewing and differentiating cells in a single cell division.
With this mechanism, the stem cell pool is maintained and the long-term homeostasis and regeneration of tissues can be preserved throughout the entire lifespan [17].
Through these mechanisms stem cells participate in ontogenesis, regeneration or reproduction of organisms.
Results indicate that miR-145 suppresses syndecan-1 and, by this mechanism, up-regulates stem cell factors and induces cell senescence and differentiation.
However, application of this mechanism to a stem cell has several problems, with regard to the robustness of the number distribution of each cell type, the need for fine-tuning of the noise amplitude, and further difficulty in achieving more than two cell types, as already described in the reply to the third question of the first reviewer.
