In a scratch wound assay, cells are treated with inhibitors of Rho kinase. What would be observed?

#Unit 2. Cellular Organization

  1. The cells completely close the scratch, and only lamellipodia and filapodia are seen with actin staining.

  3. The cells are stimulated to undergo mitosis.

  4. The cells migrate into the scratch, but no stress fibers can be observed with actin staining.
