However, one study unexpectedly found that adult human peripheral blood mononuclear cells, which are genetically stable and mainly terminally differentiated cells with a limited lifespan, express OCT4; this finding challenges the paradigm of OCT4 as a marker of pure stem cells and provides novel insight into the role of OCT4 in fully differentiated cells [ 11].
To evaluate whether these different expression patterns of angiogenic markers between pure and coexistent DCIS merely reflect an unequal distribution of DCIS with respect to histopathological and clinical features between both groups, possible associations with nuclear grading, ER-, PR-, and Her-2/neu-status and patients' age were analysed.
This would be of immense use in unambiguous identification and protection of rice hybrids, including marker-assisted production of pure hybrid rice seeds in India (Ngangkham et al. 2010; Anand et al. 2012).
Recently, CD24 was used as a single marker for isolation of pure populations of the luminal and basal compartments of the mouse mammary epithelium.
Determination of these angiogenic markers in pure DCIS may therefore facilitate discrimination of a more angiogenic subset with a potentially higher risk of progression.
We have therefore developed methods and vectors to produce homogeneous hESC lines with fluorescent and drug-selectable markers that permit isolation of pure populations of labeled stem cells and hESC-derived cardiomyocytes.
Key to this approach is the use of a differentiation protocol that allows both rostro-caudal and dorso-ventral patterning of hPSC-derived neural progenitors (Kirkeby et al., 2012a), and the use of the CORIN and SOX1 markers to obtain pure populations of cells.
Failure to detect autoAbs response to the hypocretin peptides in NC might be related to the prevailing concept of autoAbs being the pure markers of autoimmune disease.
In addition to the established and pure markers of myocardial necrosis, cTnT and cTnI, a range of other biomarkers have been proposed to aid triage in suspected NSTE-ACS.
Flow cytometry using antibodies against the fibroblast marker, CD90, and the macrophage marker, CD14 (Abcam), led to the identification of pure FLS (>90%CD90+/<1%CD14+D14+).
Analysis of simulated data using these markers did show a percentage (<2%) of pure lodgepole pine that were misassigned as hybrids (Cullingham et al. 2012).
