Fig. 5From: Characterization of MCF-12A cell phenotype, response to estrogens, and growth in 3DContraction of collagen gels after 14 days in culture. The addition of MCF-12A cells to rat-tail collagen gels results in a decreased gel diameter compared to acellular gels. MCF-12A-derived BF9 cells cause a similar extent of contraction. Asterisks signify gels that are significantly more contracted (p-value < 0.05) than acellular gelsBack to article page
