Figure 4. — Schematic representation of the FGF2-mediated cell-cell adhesion model. HSPG-bearing CHO (HSPG/CHO) cells are seeded, allowed to reach confluence and incubated with or without FGF2. Next, FGFR1-bearing CHO (FGFR1/CHO) cells are incubated onto the HSPG/CHO cell monolayers. Finally, FGFR1/CHO cells adherent to the HSPG/CHO cell monolayers are counted under the microscope.
