High-throughput screening of cellular features using high-resolution light-microscopy; application for profiling drug...

Area of Science:

• Cell biology
• Microscopy
• Drug discovery

Background:

• High-resolution light microscopy and high-throughput screening are key for cellular phenotype characterization.
• Integrating these methods for detailed cellular response analysis in cell-based screening presents a significant challenge.

Purpose of the Study:

• To develop and apply an automated screening microscope platform for rapid, high-resolution image acquisition and interpretation.
• To identify natural extracts affecting cellular structures, specifically focal adhesions, using the developed platform.

Main Methods:

• Development of a screening microscope platform for automated, high-speed, sub-micron resolution image acquisition.
• Implementation of an analysis pipeline quantifying subcellular features and comparing distributions between treated and control cells.
• Screening of 2200 natural extracts for their effects on focal adhesion structure and organization.

Main Results:

• Successful development and application of the automated screening microscope platform.
• Identification of 15 natural extracts demonstrating significant effects on focal adhesion structures.
• Further fractionation and characterization of effective extracts using the same microscopy system.

Conclusions:

• The developed platform effectively combines resolution, throughput, and multi-parametric analysis for cell-based screening.
• This integrated approach is valuable for biomedical research and accelerates drug discovery processes.
• The identified extracts provide starting points for further investigation into molecular and cellular responses.
