Schematic representation of experimental plan. A tissue pool has been created by combining lung 1, lung 2, and lung 3, respectively, which were obtained from either frozen or fresh samples. Pool of frozen or fresh tissue was divided in two equal parts, one for the SGC and another for the GTC technique. To test technique's reproducibility, each divided part was sub-divided into three identical parts (triplicate approach).
