Morphometric data (mean ± s.d.) reconstructed from µCT images. sum of vessel length of the entire coronary arterial trees (down to the terminal vessels reconstructed from µCT images) in a mouse; sum of intravascular volume of the entire coronary arterial trees in a mouse; CSA averaged over all vessels of an entire coronary arterial tree; BW, body weight; stem–crown number, the total number of stem–crown units in an entire coronary arterial tree; mean ± s.d., the and BW were averaged over mice in each age group; the and stem–crown number were averaged over all coronary arterial trees in each age group.
