In some cases, such isolation is a consequence of the use of distinct cell-restricted promoters [ 10, 32].
Differences between the various studies of coronin-1A null T cells regarding TCR-mediated activation might be explained by the use of distinct genetic backgrounds and/or distinct cell systems of analysis (transgenic vs. polyclonal, CD4+ vs. CD8+ T cells; with dissimilar signaling potencies, [21] [23], [52] and see below).
In an attempt to establish the identity of other possible receptors for the Opc protein, studies were undertaken using several distinct cell lines of human origin.
We used two distinct cell commitment scenarios to obtain high resolution around the early phase of commitment and lineage specification.
Differing recognition patterns of innate versus adaptive cells is accomplished via the use of distinct receptors.
Other limitations are the use of distinct EPC populations, routes of delivery used and timing of cell delivery, all variables rendering cross-sectional comparison difficult [ 111].
As such, the data from this study should be considered in the context of limitations of the approach used to target expression of PyMT to distinct cell populations.
Reproducible isolation using distinct cell surface antigens is now regarded as a required characteristic of CSCs [ 14].
These differences could be the result of the distinct cell lines used in the two studies, the use of soluble collagen compared with collagen-coated surfaces, or the influence of DDR2 expression on integrin activation.
Distribution of cells in distinct cell cycle phase was determined using ModFIT cell cycle analysis software.
Engulfing cells use distinct cell-surface receptors to recognize the surface features of apoptotic cells and initiate the extension of pseudopods around their targets (Elliott and Ravichandran, 2010).
