Kidney mechanical testing. Results for unconfined compression testing (blue), elastography (orange), and indentation testing (grey). The low range (yellow bar) and high range (green bar) represent a ±0.5 SD from mean values of porcine compression testing .7% PVA at 3 freeze-thaw cycles, 9% PVA at 2 freeze-thaw cycles, and 10% PVA at 2 freeze-thaw cycles were chosen as the PVA conditions best suited to replicate porcine kidney tissue properties.
