You have been culturing $ cells because they have the ability to make bucks. A recent report in the literature indicates bucks production can be increased by culturing cells n a fibronectin substratum. The investigators did not study $ cells, but rather developed their culture system for a different cell type.

Design a culture system to include a fibronectin substratum for the $ cells.

How would you determine if the culture system was optimal?

How would you determine if your bucks increased?
