Poster summary

There remains much interest in improving cryopreservation techniques for advanced therapy medicinal products. Here, we evaluated several xenogeneic-free, pathogen-inactivated and non-inactivated human platelet lysate-based formulations for the cryopreservation of bioengineered tissues (artificial dermis). The formulations are under a bidding process with MD Bioproducts (Zurich, Switzerland) and are proprietary. Amongst all formulated solutions, solution 5' preserved the viability and the phenotype of embedded cells and preserved the matrix integrity and biomechanical properties similar to those of the standard cryopreservation solution. The solutions were stable at -20ºC for 3 and 18 months, respectively. Finally, we established that there is, at least a 2-hour window in which thawed tissue and cells, maintain optimum viability immersed in the formulated solutions. In summary, our results show that inactivated human platelet lysate-based solutions are efficient and safe candidates to cryopreserve bioengineered tissues and offer an alternative to commercially available cryoprotective solutions.
