We have recently introduced a novel porous and elastic membrane for in vitro cell-stretch models of the lung cultured under ALI conditions (Doryab et al., 2020). This innovative hybrid biphasic membrane, henceforth referred to as Biphasic Elastic Thin for Air-liquid culture conditions (BETA) membrane, was developed to optimize membrane characteristics for the two phases of cell-stretch experiments under ALI conditions, namely the initial cell seeding, attachment and growth phase under submerged cell culture conditions (phase I) followed by an ALI acclimatization and cell-stretch phase at the ALI (phase II). This patented aerosol-cell exposure unit has recently been made commercially available as VITROCELL® Cloud MAX.
