While previous studies have examined neuronal interactions with synthetic structures, how neuron populations selectively navigate confined areas has been underinvestigated. This work interrogates neuronal responses to spatial constraints by confining neuron-like PC12 cell populations inside 3D-printed microenvironments on glass substrates. The microenvironments enable localized interaction with neighboring cells and the printed structure. Key parameters analyzed include neurite outgrowth, migration, and cell proliferation in relation to confinement. The results reveal that PC12 cells in contact with structural features exhibit longer neurite outgrowth and a preference for maintaining contact rather than occupying open spaces within the confinement. Time-lapse imaging confirms PC12 cells actively seek structural interactions, a behavior not widely investigated up to now. These findings underscore the role played by spatial constraints in neuronal network formation and highlight how structural contact could guide neuronal behavior in confinement. The insights gained could enhance neurobiological modeling and tissue engineering, and suggest that a better understanding of spatially structured environments could improve neural tissue models. Future research could expand on these findings by varying confinement geometries and materials and investigating additional aspects of cellular behavior, to possibly advance bioengineering efforts that aim to create brain-like tissue structures and neural interfaces. date: 2025 id_scheme: DOI id_number: 10.11588/heidok.00037080 ppn_swb: 1933375329 own_urn: urn:nbn:de:bsz:16-heidok-370805 date_accepted: 2025-07-24 advisor: HASH(0x558b45958c00) language: eng bibsort: CASALESTEPTHEEMERGEN full_text_status: public place_of_pub: Heidelberg citation: Casale, Stephen Louis (2025) The Emergent Properties of PC12 Populations in Confinement.
