The experiments show that when Amotl2a is absent, the migrating cell cluster becomes larger, with the highest levels of cell division occurring at its trailing end.
Cell volume regressed profoundly to below sham levels, indicating the large diminution of cell size which accompanies mechanical unloading.
CY treatment increases the concentration of extracellular DNA levels due to the large amount of cell death, so it seems logical to surmise that DNAse may reduce the local concentration of DNA in the spleen and thus, impair the autoantigen-mediated expansion of high affinity DNA-reactive B cells.
Wingless queens from northern Sky Islands possess smaller discs and low levels of cell division (Fig. 4 h), whereas those from the southern Sky Islands possess large imaginal discs and high levels of cell division.
DNA flow cytometry is a well-known technique that is commonly used to analyze the ploidy level of large cell populations [ 16], however, the destructive sample preparation (e.g. nuclear cell suspension) impairs any in vivo cell- or tissue-specific ploidy determination [ 17].
In the medulla, CK1δ was expressed at moderate levels by a large fraction of cells.
A recent analysis (cite) of this and other human and animal model data confirms that the heteroplasmy levels measured in large numbers of cells follow a distribution from theoretical population genetics based on random genetic drift [ 48].
We first established a standard curve so that the total cellular FtsZ level of an individual cell can be easily inferred from its integrated green fluorescence of FtsZ-mEos2 instead of relying on an average expression level measured on a large population of cells using immunoblotting (Figure 6A).
In such applications, stem cells are often selected as the cell source, as they have the capacity to expand to provide a large pool of cells with varying levels of self-renewal and differentiation potential (stem cells, progenitor cells, terminally differentiated cells) necessary to meet desired therapeutic goals.
Most laboratory techniques for growing bacteria use high levels of nutrients to produce large amounts of cells cheaply and quickly.
