Table 1. Dye coupling of INS-1E cells after a 24 h exposure to either IL-1β or metformin.
| Condition | Extent of couplinga | Incidence of couplingb | Coupling indexc(a.u.) | Number of microinjections |
|---|---|---|---|---|
| Control | 2.5±0.2 | 28 (65.1) | 162.1 | 43 |
| IL-1β | 1.5±0.1*** | 12 (41.4)* | 60.0 | 29 |
| Metformin | 1.4±0.1*** | 8 (32.0)** | 43.5 | 25 |
a
Data are mean±S.E.M. values of the number of cells featuring labeling by Lucifer yellow, in the number of microinjections indicated in the right column. ***P<0.001 compared with the value in control cells, as evaluated by ANOVA.
b
Number and (proportion) of injections resulting in the intercellular transfer of the dye. *P<0.04, **P<0.008 versus control as evaluated by the non parametric χ2-test.
c
Given by average extent χ percentage of coupling.
