CONTENTS ----------- Folders contain data for all three groups (26-day decellularised, 4-day decellularised and native). The folder 'DNA Quantification' contains data file with raw data and calculation of DNA quantity. The folder 'Histology Images' contains full size histology images used in the publication. The folder 'Failure testing' has subfolders 'Raw data', 'Analysis files'and 'Data prepared for Matlab analysis'. 'Raw data' is data taken directly from Instron testing. 'Analysis files' is the raw data with some analysis.'Data prepared for Matlab analysis' is the data that was used in Matlab to plot stress-strain graphs. The folder 'Stress relaxation' has subfolders 'Raw data', 'Analysis files'and 'Data E(t) vs time'. 'Raw data' is data taken directly from Instron testing. 'Analysis files' is the raw data with some analysis.'Data E(t) vs time' is the data that was used to plot relaxation modulus graphs. 5.
