CELLS-FJ@FBL

Chemotaxis is a mechanism by which migrating cells find their destination, but it is still not clear how a chemical gradient is established.

Which ONE of the following is NOT LIKELY to be involved in establishing, utilizing and navigating a chemical gradient by migrating cells?

A

Secretion of chemical attractant by target structures.

B

Degradation of chemical attractant by migrating cells.

D

Neuronal control of migrating cells.

E

Cellular contact inhibition.
