Using a microscope system with region-of-interest illumination capability, it is possible to mark a subset of mitochondria within a cell.
Thus it marks a subset of latently infected cells.
The proliferating cell nuclear antigen (PCNA) marked a subset of CA1 pyramidal neurons, but these were, surprisingly, not marked by proliferation marker Ki67.
Gata2/3 and Tal1/2 also mark a subset of differentiating GABAergic neurons in the r1.
Rap2 did not notably overlap with Rab11 that also marks a subset of endosomal vesicles (data not shown).
Indeed, out of the 68 tested genes, six were specifically expressed in C-LTMRs, as they only marked a subset of GINIP+ neurons that do not bind IB4.
Although RAD51 foci may only mark a subset of the double-strand breaks, the number of residual RAD51 foci per cell was not invariably lower than the number of residual γH2AX foci (Fig. 5e).
Such bivalent domains are thought to mark a subset of key developmentally regulated genes in ES cells that are kept at a low transcriptional rate., The enrichment of the bivalent marks at conserved domains overlapping with sites for the recruitment of the core pluripotency factors OCT3/4, SOX2 and NANOG originally suggested a functional relationship between such bivalent domains and pluripotency.
Several Cre-expressing mouse lines are available, which label various cardiac cell types including neural crest (Wnt1-Cre), (pro epicardium (Wt1-Cre, Tbx18-Cre), the first and second heart fields (Nkx2-5) and the second heart fields (Mef2c-Cre, Isl1-Cre, Tbx1-Cre), the latter of which also marks a subset of the right ventricle endocardium.
In addition, the expression of the tight junction proteins claudin-3 (Cld3) and Cld4 has been shown to mark a minor subset of TECs at E13 in mice, representing an mTEC progenitor subset at this developmental stage that is able to generate Aire-expressing mTECs 42.
