Abstract :In this study, SH-SY5Y neuroblastoma cells were bioprinted using a GelMA/HAMA bioink, and the formation of spheroids was observed to initiate as early as day 3. This observation is significant as it indicates that the specific composition of the bioink can have a profound impact on cellular behavior and the spheroid formation process. Comparatively, in earlier studies utilizing an alginate/gelatin-based bioink, spheroid formation only became noticeable around day 5, suggesting that the GelMA/HAMA bioink provides a more conducive environment for earlier cellular aggregation and organization. The results of this study highlight the critical role of bioink formulation in influencing the biological responses of cells within a three-dimensional (3D) microenvironment. The quicker spheroid formation observed with the GelMA/HAMA bioink may be attributed to its biochemical properties, such as enhanced cell adhesion, improved mechanical strength, and the ability to mimic the extracellular matrix. These properties provide an optimized platform for cell-cell and cell-matrix interactions, promoting accelerated tissue-like structures. This research underscores the importance of systematically investigating the effects of bioink compositions on cellular biology. Understanding the interplay between bioink components and cellular behavior is essential for improving the design and application of bioprinting technologies. Such insights are invaluable for advancing tissue engineering, regenerative medicine, and the development of disease models. Ultimately, the findings pave the way for creating more precise and effective biofabrication strategies, emphasizing the need for tailored bioink formulations that support specific biological outcomes in various applications.
