Background:

Cellular spatial distribution influences tissue function.
Density-based clustering algorithms like DBSCAN analyze cell positioning.
Standard DBSCAN requires careful parameter selection and has limitations in identifying individual cell positions.

Purpose of the Study:

To develop advanced DBSCAN algorithms for precise cell localization analysis.
To improve the characterization of cell clusters and their edges.
To establish a link between cell localization and tissue physiology.

Main Methods:

Developed three extensions to the DBSCAN algorithm.
Implemented automated parameter identification for reliable cell cluster detection.
Enhanced identification of cluster edges and relative cell positioning within clusters.
Created a user-friendly OpenSource software package (DBSCAN-CellX).

Main Results:

DBSCAN-CellX accurately identifies cell clusters and their boundaries.
The enhanced methods provide improved characterization of cell positioning within clusters.
Applied to cellular monolayers, demonstrating the utility of the extensions.
Validated the importance of the developed extensions for cell culture analysis.

Conclusions:

The novel DBSCAN-CellX extensions significantly improve the analysis of cell spatial distribution.
Accurate cell localization analysis is essential for understanding tissue physiology.
DBSCAN-CellX offers a robust tool for cell biology research and tissue analysis.
