Internalization of rhodamine-conjugated polyinosinic-polycytidylic acid (Poly(I:C)) by rBM-MSCs. (a) Representative photomicrographs from time-lapse video microscopy, each corresponding to the indicated time points following the addition of rhodamine-conjugated Poly(I:C) to the culture medium, showing the overlay of phase contrast and spinning disk confocal fluorescence images of one cell (rhodamine-conjugated Poly(I:C) is shown in red). Scale bar: 10 μm. (b) On the left, phase contrast image of a cell at 1 h after incubation with rhodamine-conjugated Poly(I:C). On the center, overlay of the phase contrast image and the maximum intensity projection of a z stack showing rhodamine-conjugated Poly(I:C) in red. On the right, orthogonal projections (XZ, YZ) of the z stack showing the internalization of rhodamine-conjugated Poly(I:C) (in red) by this cell. Scale bar: 10 μm.
