Therefore, for any other data point x k of the sorted table, add x k into cluster C i if cluster purity is decreased to an acceptable level (threshold λ), add data point x k into cluster C i. Otherwise, DBSCAN algorithm recognizes next core point and generate cluster by the above method.
Compared with the miRNAome data of BCSCs sorted from breast cancer cell line MCF-7 in previous research [ 26], we discussed the key miRNAs, their essential function and possible mechanisms in regulating the stemness of BCSCs.
This property of the sorted data explains much of the Pearson coefficient behavior in the correlation analyses.
Q-methodology involves 3 stages: developing a set of statements to be sorted; sorting of those statements by participants along a continuum of agreement; and analysis and interpretation of the sorted data [ 28, 29].
This possibility was confirmed in PCR analysis where we did not detect any undeleted fragment of the R26R allele using genomic DNA of the sorted cells (data not shown).
As for the ESC data, the sorted populations comprise a cellular hierarchy that gives rise to all of the mature cell types of the blood system.
The research team then performs an analysis of the sorted and rated data using quantitative techniques of multidimensional scaling [ 37] and hierarchical cluster analyses [ 38].
A cut point T is the midpoint between two contiguous data points in the sorted array.
After sorting, the purity of the sorted populations was determined by FACS reanalysis of an aliquot of cells, and was 90% on average (data not shown).
Viability of the sorted SP and MP cells was identical (data not shown).
