Embryonic Cardiomyocyte Proliferation Quantification (EdU Incorporation) Dataset

This file contains per-image (or per z-frame) counts used to quantify embryonic cardiomyocyte proliferation by EdU incorporation. Each row corresponds to one quantified imaging field/frame from a given animal, stage, and series, reporting total nuclei counted, cardiomyocyte nuclei split into EdU-positive vs EdU-negative, and the resulting cardiomyocyte EdU+ fraction.Edu_data.csv – column definitions (one row = one image field / frame)ImageNumber: Primary image/field identifier (index from the analysis pipeline).ImageNumber.1: Duplicate of ImageNumber (export artifact; same ID repeated).Metadata_Animal: Animal ID (biological replicate).Metadata_Framez: Z-frame index (or frame number) within the acquisition stack.Metadata_Series: Series index (if multiple series per sample).Metadata_Stage: Developmental stage label (e.g., “10p5” = E10.5; “11p5” = E11.5).Total Cell Count: Total nuclei counted in the field/frame (all cells).Positive Cell Count: Count of cardiomyocyte nuclei scored as EdU-positive (proliferating CM nuclei).Negative Cell Count: Count of cardiomyocyte nuclei scored as EdU-negative (non-proliferating CM nuclei).Rest Cell Count: Nuclei not included in CM positive/negative counts (e.g., non-cardiomyocyte nuclei and/or excluded objects, depending on the scoring pipeline).CM_pos: Fraction of proliferating cardiomyocyte nuclei in that field/frame (typically computed as Positive Cell Count / (Positive Cell Count + Negative Cell Count)).
