3D-bioprinting of aortic valve interstitial cells: impact of hydrogel and printing parameters on cell viability

Biomedical Materials 2023 Volume 18, Article 015004

Calcific aortic valve disease (CAVD) is a frequent cardiac pathology in the aging society. Although valvular interstitial cells (VICs) seem to play a crucial role, mechanisms of CAVD are not fully understood. Development of tissue-engineered cellular models by 3D-bioprinting may help to further investigate underlying mechanisms of CAVD. VIC were isolated from ovine aortic valves and cultured in Dulbecco’s modified Eagle’s Medium (DMEM). VIC of passages six to ten were dissolved in a hydrogel consisting of 2% alginate and 8% gelatin with a concentration of 2 × 106 VIC ml−1. Cell-free and VIC-laden hydrogels were printed with an extrusion-based 3D-bioprinter…
