abstract = "Introduction: The NT2/D1 embryonal carcinoma cell line represents a well-established in vitro model of
human neurogenesis. It’s widely used for studying neurodevelopmental processes, neurotoxicity, and
neurodegenerative disorders. The utilization of alginate fibers as a 3D cell culture system offers a biocompatible and structurally supportive environment for neural differentiation and maturation of cells,
making it a suitable tool for investigating neurodevelopmental processes.
Methods: In thisstudy, we evaluated the alginate microfibers as a 3D modelsystem for in vitro neural differentiation of NT2/D1 cells.We described the immobilization of NT2/D1 cellsin alginate microfibers and
the effect of propagation in this 3D model on morphological features, viability, and proliferation of immobilized cells. We also assessed the RA-induced initiation of neural differentiation of NT2/D1 cellsin alginate microfibers by comparison with the initiation of neural differentiation in adherent 2D cell culture.
Results: Our results showed that immobilized NT2/D1 acquired morphological features characteristic
of cells propagated in 3D model systems and retain viability, proliferative capacity, and ability to attach
to adherent surfaces. In addition, immobilized NT2/D1 cells preserved neural differentiation capacity.
Upon RA induction we detected a marked decrease in the expression of specific pluripotency-maintaining markers, SOX2, OCT4, and NANOG. Consecutively, the expression of early neural markers, SOX3,
PAX6, and miR219 was significantly increased.
Conclusion: Neural differentiation of NT2/D1 cellsimmobilized within alginate fibersrepresents a highly
promising 3D modelsystem forstudying human neurogenesis and offers a valuable platform forscreening the effect of drugs and bioactive compounds on human neural differentiation.",
