“…However, the value of E SDS-CO2 in SDS50/ET system decreases compared with SDS50, and the decreased value is more than compensated by the interaction energy between SDS and ethanol. Generally speaking, nonpolar tails of SDS molecules can interact with CO 2 molecules and the polar heads which are turned out to interact with alcohol molecules (Chaschin et al 2020 ). Ethanol can reduce the solute self-interaction and improve the solute–solvent attraction forces to enhance the dispersion of SDS in scCO 2 .…”

Fish swim bladders used to be considered as byproducts or waste in fishery; however, they are potential materials for biological medicine with abundant collagen. In this work, an efficient noncytotoxic decellularization process using sodium dodecyl sulfate (SDS) ternary system assisted with supercritical carbon dioxide (scCO2) as the green extraction fluid and ethanol (ET) as the cosolvent has been developed to harvest acellular fish swim bladders (AFSBs). The experimental results show that the tissue treated by SDS assisted with scCO2 and ethanol at 37 °C and 25 MPa can be decellularized thoroughly and maintains intact fibers and uniform pore distribution, which resulting in a tensile strength of 5.61 MPa and satisfactory biocompatibility. Meanwhile, the residual SDS content in scCO2/SDS/ET ternary system is 0.0122% which is significantly lower than it in scCO2/SDS system due to the enhanced mass transfer rate of SDS in tissues by scCO2 with ethanol. The synergy between SDS and ethanol can enhance the diffusion coefficient and the solubility of SDS in scCO2, which reduced the contact time between SDS and tissues. Meaningfully, the results obtained in this work can not only provide a novel strategy to produce acellular matrix with superior properties, but also offer a further understanding of the decellularization through scCO2 extraction processing with the synergy of suitable detergent/cosolvent.

“…The obtained acellular tissue showed no decrease in mechanical strength ( Sawada et al, 2008 ). Bakuleva and her team have recently modified this technique and applied it to BJV tissues ( Chaschin et al, 2020 ; Chashchin et al, 2021 ). They developed a “hybrid” treatment which consisted of a short exposure to the standard detergent solution (1% v/v sodium dodecylsulphate) followed by an exposure to the scCO2 with Tween-80, in order to achieve complete decellularization and to preserve the ECM components (such as collagen and elastin) and structures.…”

“…Chashchin et al deposited chitosan from carbonic acid solution to decellularized BJVC, endowing the conduit a smooth intima surface and resistance to calcification. Meanwhile, the coating was also found to have significantly improved the strength and the elasticity of the decellularized conduit (Chaschin et al, 2020;Chashchin et al, 2021). Krasilnikova et al applied globular chitosan, which had better diffusion and tissue-penetration characteristics than linear chitosan, to both cellular and acellular BJVCs.…”

Right ventricular outflow tract (RVOT) reconstruction is a common surgical method to treat congenital cardiac lesions, and bovine jugular vein conduit (BJVC) has become a prevalent candidate of prosthetic material for this procedure since 1999. Although many clinical studies have shown encouraging results on BJVCs, complications such as stenosis, aneurysmal dilatation, valve insufficiency, and infective endocarditis revealed in other clinical outcomes still remain problematic. This review describes the underlying mechanisms causing respective complications, and summarizes the current technological development that may address those causative factors. Novel crosslinking agents, decellularization techniques, conduit coatings, and physical reinforcement materials have improved the performances of BJVCs. The authors expect that the breakthroughs in the clinical application of BJVC may come from new genetic research findings and advanced characterization apparatuses and bioreactors, and are optimistic that the BJVC will in the future provide sophisticated therapies for next-generation RVOT reconstruction.
