The appearance of MTA1 protein in the principal cells from day 35 coincides with the complete differentiation of principal cells from columnar cells and their further differentiation to principal cells and apical cells.
Thus, the following study is the first report performing a thorough characterization of global miRNA expression levels encompassing the complete differentiation scheme from hES cells to terminally differentiated OLs.
The value of FST can theoretically range from 0 (no differentiation) to 1 (complete differentiation, in which subpopulations are fixed for different alleles).
This treatment improved the discrimination power (DP) and provided objective results, achieving a complete differentiation among different brands and a partial differentiation within pen inks from the same brands.
FST values range from 0 (no differentiation) to 1 (complete differentiation) and can provide a measure of the action of natural selection on these regions.
We calculated Wright's fixation index (FST) (Wright, 1949) as a widely used method to test the population differentiation with values ranging from 0 (homogeneous population) to 1 (complete differentiation).
This clearly implies that EVPs initially express Sox18 and then give rise to TA and D cells through complete differentiation.
FST ranges from 0 to 1 with an estimate of 0 indicating no population differentiation and an estimate of 1 indicating complete differentiation.
Complete differentiation was reached after 7 days.
Although a small degree of differentiation was observed with an inducible MYB shRNA alone, a more dramatic effect was apparent from the synergy between MYB knockdown and (otherwise) marginally-effective concentrations of DIAs, which resulted in essentially complete differentiation.
Further, while these changes appear modest (i.e., <2-fold change between treated and untreated cells), the changes observed during complete physiological differentiation from slender to stumpy forms are also in this range (Table 1, columns 5 and 6; see also Table S1 in the supplemental material) (32, 33).
