Experimental and reconstructed age-size distributions for representative experiments from Stewart et al.[25]( f 1 ) and Wang et al.[26]( s 1 ). (A,B) Experimental age-size distributions for representative experiments f1 (A) and s1 (B). The frequency of cells of age a and size s in the population is represented by the color at the point of coordinate a on the x-axis and s on the y-axis, according to the scale indicated to the right of the figure. (C,D) Reconstruction of the distributions using the Age Model (C: reconstruction of the data f1 shown in panel A; D: reconstruction of the data s1 shown in panel B). These reconstructed distributions were obtained from simulations with the Age Model using a division rate estimated from the data (C: from f1, D: from s1). The growth functions used for the simulations are detailed in the Methods section. (E,F) Reconstruction of the distributions using the Size Model (E: reconstruction of the data f1 shown in panel A; F: reconstruction of the data s1 shown in panel B). These distributions were obtained from simulations with the Size Model using a division rate estimated from the data (E: from f1, F: from s1) with an exponential growth function (see Methods).
