Collagen 1 and 3 mRNA expression determined by RT-PCR. PascualGemma SotomayorSandra RodríguezMarta BayonYves M. BellónJuan 2013 <p>Stacked bar charts of the relative mRNA amounts, collagen 1 (white bar) and 3 (black bar), recorded for Bard mesh<sup>TM</sup> (A), Physiomesh<sup>TM</sup> (B), the new composite mesh (C) and Ventralight<sup>TM</sup> (D) at the different study times (left panel). Results are the mean ± SEM of three experiments. Gene expression was normalized to that of the GAPDH gene. Agarose gels obtained (right panel). Mw: molecular weight markers; 1/2: 14 days postimplant; 3/4: 90 days postimplant; N: negative. Col 1: *, p<0.05 and **, p<0.01 vs. Bard<sup>TM</sup> at 90 days; #, p<0.01 vs. new composite mesh at 14 days. Col 3: |, p<0.05 vs. Bard<sup>TM</sup> at 90 days; †, p<0.05 and ††, p<0.01 vs. Physiomesh<sup>TM</sup> at 14 days; ‡, p<0.05 vs. new composite mesh at 14 days.</p>
