It is widely recognized that fluorescent labeling of cells is an effective means to determine total cell numbers or how many viable cells exist in a sample. Flow cytometry combined with fluorescent staining is a powerful tool to analyze heterogeneous cell populations. Fluorescein diacetate (FDA) and its derivatives are non-fluorescent molecules that diffuse into cells and are hydrolyzed by intracellular non-specific esterases to give fluorescent products. The fluorescent products can be accumulated only in those cells that have intact cell membranes; therefore, dead cells with leaky membranes are not stained. The precise kinetics of membrane transport and intracellular hydrolysis of FDA and its analogs (such as CDCFDA) are related to cellular functions, thus FDA labeling can be used for monitoring cells by flow cytometry or fluorescence microscopy. The fluorescence intensity of labeled cells by FDA dyes varies considerably among cell lines and strains, probably because of differences in intracellular esterase activity. CFSE is an amine-reactive FDA derivative that is widely used for monitoring cell proliferation with a flow cytometer.

Figure 1. Treponema pallidum-platelet interactions. (A) Flow cytometry isolates the co-localized platelet and treponeme populations by SSC and FSC gating. Dot plots of (B) CFSE-labeled heat-treated treponemes demonstrate reduced binding to human platelets labeled with PE/Cy5 anti-CD41a compared with (C) CSFE-labeled viable treponemes. (D) CFSE-labeled viable treponemes bound significantly more human platelets (mean = 55.13% ± 2.91 [SD] *P<0.0001) compared with heat-treated treponemes (mean = 19.05% ± 2.29 [SD]) following co-incubation for 16 hours at 37°C and ~ 5% oxygen. Results represent the mean of three independent experiments with statistical significance computed by two-way ANOVA, with a minimum of 3 replicates per sample type per experiment. (E) Darkfield microscopy FOV counts (20 random locations/slide) demonstrate viable treponemes bind significantly more human platelets (mean = 31.73% ± 1.19 [SD] *P<0.0001) than heat-treated treponemes (mean = 6.47% ± 1.19 [SD]) following co-incubation at 5% oxygen at 34°C for 48 hours. Results represent the mean of three independent experiments with statistical significance computed by unpaired two-tailed Student’s t test, n = 3. (F) Heat-treated treponemes (top) are non-motile yet morphologically similar to viable treponemes (bottom). (G) Darkfield microscopy at 1000x magnification demonstrates platelet interactions are reversible. Image capture from video micrographs show edgewise attachment of a treponeme to an activated platelet (0.01 s to 8.10 s) which then detaches and moves away (9.05 s).

Figure 2. Effects of GTM (1, 1/2 and 1/4 -fold serum concentrations) and probenecid (Prob, 80 μM) on the intracellular accumulation of 6-CF in CHO-hOAT1 cells (left) and 5-CF in HEK293-hOAT3 cells.(right). The effects of GTM on the uptake activity of hOAT1 and hOAT3 are shown in Fig. 6. GTM at 1/4−, 1/2− and 1-fold serum concentrations significantly reduced the intracellular accumulation of 6-CF, an OAT1 substrate, by 43.9, 41.9 and 58.1%, respectively, when compared with blank serum specimen at corresponding concentrations. Likewise, GTM at 1/2− and 1-fold serum concentration significantly reduced the intracellular accumulation of 5-CF, an OAT3 substrate, by 36.4% and 31.3%, respectively, when compared to blank serum specimen at corresponding concentration. As positive control inhibitors of hOAT1 and hOAT3, probenecid (80 μM) significantly reduced the intracellular accumulation of 6-CF and 5-CF by 50.4 and 50.7%, respectively. These in vitro studies indicated that GTM significantly inhibited the uptake transport mediated by hOAT1 and hOAT3. *P < 0.05, **P < 0.01 and ***P < 0.001.
