Pulmonary endothelium is considered the compartment most susceptible to preservation damage. This investigation was designed to analyze the efficacy of an original, University of Parma low-potassium-albumin solution (SPAL UP) on cultured human pulmonary artery endothelial cells (HPAEC) and to compare its effects with those of University of Wisconsin solution (UW) and Euro- Collins solution (EC). Cryopreserved HPAEC tertiary cultures were inoculated at the density of 5000 cells/cm2 in 9-cm2 well-plates; subcultures were then incubated at 10°C for 6 hr and 16 hr in 2 ml/well of SPAL UP, UW, and EC. The HPAEC viability after incubation was assessed by evaluating the total protein content and the expression of cytotoxicity, and by analyzing the rate of protein synthesis and expression of cellular functionality after stress. Results after 6 hr of preservation showed that SPAL UP had a less significant cytotoxic effect than EC, exerted a less depressing effect on cellular metabolism, and enhanced functional recovery of endothelial cells compared with UW. At the second time interval (16 hr), SPAL UP provided a less cytotoxic effect than UW; besides, SPAL UP-induced cytotoxicity was similar to that of warm control. In conclusion, in vitro preliminary data regarding the use of SPAL UP in HPAEC preservation suggest its suitability as solution for prolonged lung protection.
