Fig. 10From: Challenges of aortic valve tissue culture – maintenance of viability and extracellular matrix in the pulsatile dynamic microphysiological systemCellular density after pulsatile dynamic vs. static AV tissue culture: A Density alteration is visible in DAPI stained nuclei of native (0 days, left) and statically incubated pAV tissue Sects. (14 days, right). B Cellular density was assessed and relativized against AV cross section area due to valvular shrinkage (n = 6, Scale bar: 300 µm; two-way-ANOVA; * p < 0.05; no significance shown for lysis control)Back to article page
