Self-assembled monolayers (SAMs) formed from long chain alkane thiols on gold provide well-defined substrates for the formation of protein patterns and cell confinement. Microcontact printing of hexadecanethiol using a polydimethylsiloxane (PDMS) stamp followed by backfilling with a glycol-terminated alkane thiol monomer produces a pattern where protein and cells adsorb only to the stamped hexadecanethiol region.

We describe experimental details of the synthesis of patterned and reconfigurable particles from two dimensional (2D) precursors. This methodology can be used to create particles in a variety of shapes including polyhedra and grasping devices at length scales ranging from the micro to centimeter scale.
FAQs
A signaling gradient supplies positional information by varying across developing neural tissue. Cells in different locations therefore receive different signaling cues, which can activate location-specific gene expression. Those gene-expression differences help assign regional identities and initiate distinct developmental programs, linking spatial position to the organization of neural tissue.
The resulting positional information can influence several developmental outcomes rather than cell identity alone. It helps guide cell fate, regulate proliferation, and support differentiation, allowing cells exposed to different positions within the tissue to follow distinct developmental trajectories. Coordinating these processes contributes to the formation of specialized neural regions and neuronal populations.
Organizing neural tissue along an anterior-to-posterior axis establishes an ordered arrangement of regions with different identities and functions. Signaling-dependent positional cues help translate location into regional gene-expression patterns, supporting the emergence of specialized neuronal populations. This axis-based organization provides a framework for understanding how complex nervous-system structures develop in a coordinated sequence.
Disruptions in positional signaling or the associated gene-expression programs could alter regional identity, cell fate, proliferation, or differentiation during neural development. Studying this process therefore helps researchers connect developmental patterning mechanisms with congenital disorders. The approach provides a framework for examining how abnormal organization of neural tissue may arise during development.
Stem-cell-derived neural models provide a research context for examining how positional cues generate distinct neural identities in developing tissue. Investigators can use these models to study the relationship between signaling gradients, location-specific gene expression, and neuronal differentiation. Such work can clarify developmental mechanisms and support efforts to direct cells toward specialized neural populations.
Regeneration strategies may need to recreate the positional organization that guides neural cell identity and differentiation. Understanding one-dimensional patterning informs efforts to direct developing or replacement tissue toward appropriate regional and neuronal outcomes. Its relevance lies in linking spatial cues with tissue specialization, which can help frame approaches to rebuilding organized neural structures.
