Fig. 4From: Heparan sulfate is an important mediator of Ebola virus infection in polarized epithelial cellsSemiconfluent monolayers are more susceptible to apical EBOV infection. Caco-2 cells were grown to either semiconfluence (day 4 pi) or confluence (day 6 pi) and infected with EBOV at 3 pfu/cell. The monolayers were fixed with 10% buffered formalin and examined for expression of E-cadherin and EBOV-GP by immunofluorescence microscopyBack to article page
