Tiffany Sato investigated whether asparagus can inhibit the population growth of yeast cells. She used yeast (Saccharomyces cerevisiae) as a model organism to study the anti-proliferative effects of asparagus due to similarities between yeast and cancer cells. Yeast growth was measured using spectrophotometry and viable colony counts. Results showed decreased yeast activity and fewer colonies with asparagus compared to positive controls, indicating asparagus can minimally inhibit yeast cell growth. This supports the hypothesis that asparagus compounds may reduce cancer cell proliferation.
