Fig 3. Syncytium formation induced by recombinant HMPV strains.

Fig 3

(a) LLC-MK2 monolayers in 24 well-plates were infected with rHMPV at an MOI of 0.01 in quadruplicate. On days 2 through 4 pi, pictures were taken using fluorescent microscopy in 3 random fields (20x magnification) per well and the number of nuclei per GFP-expressing cell was calculated. ***, p < 0.001 comparing all other strains to rC-85473 and °°°, p < 0.001 comparing all other strains to rCAN98–75 using Repeated Measures Two-way ANOVA. (b) An example of the observed difference in syncytium formation between the 4 recombinant strains on day 3 pi.
