Presynaptic actin nanostructures: A reproducibility case study

Area of Science:

• Cell Biology
• Microscopy
• Image Analysis

Background:

• Reproducibility in scientific research is a growing concern.
• Bioimage analysis workflows in publications often lack detailed methodology.
• The Global BioImage Analysts' Society (GloBIAS) initiative aims to improve reproducibility.

Purpose of the Study:

• To assess the reproducibility of bioimage analyses in published literature.
• To identify key practices that enhance the reproducibility of bioimage analysis workflows.
• To evaluate the challenges in reproducing findings from complex biological imaging studies.

Main Methods:

• Attempted to reproduce core findings from Bingham et al. (2023) on actin organization in presynaptic structures.
• Utilized diffraction-limited and super-resolution microscopy data.
• Performed image reconstruction, automatic registration, visual inspection, and manual annotation of approximately 35 images.

Main Results:

• Qualitative aspects of actin nanostructure analysis in bead-induced presynapses were replicated.
• The original publication lacked sufficient detail in bioimage analysis methodology, limiting reproducibility.
• Collaboration with the corresponding author facilitated partial replication.

Conclusions:

• Sharing example datasets, depositing manual annotations, and documenting manual decision criteria are essential for reproducible bioimage analysis.
• Transparent data sharing, adherence to bioimage analysis standards, and collaboration are critical for complex imaging studies.
• Improved reporting standards are needed to enhance the reproducibility of bioimage analysis.
