Plastomer tissue relevance and biocompatibility. (a) Selected true stress–elongation curves of Group 2 plastomers (lines) overlaid onto spinal cord, fetal membrane, and porcine brain tissues (symbols) found in the literature (Table S1) with similar mechanical properties. (b) Selected true stress–elongation curves of Group 2 plastomers (lines) match different types of adipose tissue (symbols). (c) The proliferation of human normal mammary epithelial and adipose-derived mesenchymal stem cells cultured onto a 300–1/70 plastomer surface and monitored by fluorescence microscopy after 1, 3, 5, and 7 days. Cells became confluent within 7 days. (d) Corresponding DNA quantification of the cultured human normal mammary epithelial and adipose-derived mesenchymal stem cells after 1, 3, 5, and 7 days.
