The differences observed in the αSMA expression, the high printability, and tunable mechanical properties of the GelMA-CBP bioinks are promising for the development of dynamic tissue models. However, further research is needed to fabricate complex models that more accurately reflect the microenvironment in the tissue. Follow up research studying the impact of the time, frequency, strain, stretching pattern, and uniaxial vs volumetric stretching is paramount to understand how cells respond to constant mechanical stimulus on top of these 3D printed materials and select the conditions that replicate in vivo biology. Other important factors to consider for future studies are how the dimensionality of the microenvironment (2D -on top vs. 3D -within the material) and the presence of soluble biochemical cues (e.g., cytokines and growth factors such as TGF-β1) impact cells. Including lung epithelial cells on top of the material and hLF within it and exposing the co-culture to immune cells and biomolecules of interest could dramatically improve the accuracy of the biomimetic lung model. Refining the mechanical properties of the constructs is also essential, since a limitation of the current model is that the viscous component of tissue is not fully recapitulated by the inks presented. Using more viscoelastic (e.g., double network) instead of mostly elastic hydrogels (i.e., covalently crosslinked) may be key to mimic the mechanical properties of the extracellular matrix in humans. This additional work is crucial for developing fully functional dynamic tissue models that can be used in lieu of animal models. We anticipate that the GelMA bioinks can be refined to overcome all these limitations and help answer critical questions related to ageing and disease tissue states.
