The fusogenic protein promotes cell fusion.

The fusogenicity of the virus allows it to enter and fuse with host cells.

The fusogen is a protein that facilitates membrane fusion.

The fusogenicities of the two viruses were compared.

Fusogens are proteins that facilitate membrane fusion.

The cells fused fusogenically.

The fusogeneity of the cells was observed under the microscope.

Fusogenesis is the process of membrane fusion between two cells.
