It is that it is a means of accomplishing three related tasks: (i) Descriptions: The model systematically establishes and differentiates the phenomena with which it is concerned by defining actors, objects and contexts, and the processes that govern them.
Late pregnancy is a critical period for mammary development, in which the functional secretory tissue of the gland is established and differentiates prior to parturition.
In contrast, DNA microarrays, first created 20 years ago, are well established and able to differentiate hundreds of specimens simultaneously.
These observations support the suggestion that the spinal cord is derived from an axial progenitor population and provide an experimental system, the aggregates of mESCs, to identify and dissect the networks that establish, maintain and differentiate this population (see also the accompanying paper in this issue: van den Brink et al., 2014).
Results An in vitro cell model of APPsw AD was established by culturing and differentiating embryonic stem cells isolated from the APPsw transgenic minipig.
In promising to deport millions of undocumented workers and build a wall across the southern border, he established his conservative bone fides and differentiated himself from the other candidates.
In a previous study by our group, ISQ values showed a low sensitivity and did not reliably predict early implant failure, and no cut-off value could be established for differentiating between success and early failure [ 16].
A PCA model was established to differentiate the wild type and mutant strains, and the results indicated that there was a clear segregation between the wild type strain and the mutants (Fig. 3a).
The cost model for each patient was established by differentiating the fixed and variable costs.
Using real-time RT-PCR analysis, we established that hEB differentiated using this optimized system progress through the normal developmental stages of cardiac lineage gene expression (Figure 5A).
