Rectangular chambers co-culture system
A plastic grid with three rectangular compartments is placed on
a 60 mm culture dish (see Fig. 3A).
Donor and target cells are
seeded on the left and right compartments, respectively, leaving
the middle one empty.
After cell growth for one day, the plastic grid
is removed and the two cells populations are placed under the
same medium for 24e48 h before challenge with VHSV at a
m.oi ¼ 0.01 TCID50/cell.
At 8 days post-infection the cells were
fixed and stained with 10% crystal violet in formaldehyde.
