Cell surface biomarker expression. a–d The MCF10A cell-formed acini in TMG and Matrigel were IF stained with either β1 or β4 integrin (red), E-cadherin (green), and Hoechst (blue). Scale bars, 100 μm. e–g The expression of CD44 in MM231 cells cultured on the three types of hydrogels were examined using IF staining. CD44, red; Col I, green; nucleus/Hoechst, blue. Scale bars, 10 μm
