Supplemental Information The ABC model We model the cell dynamics as a stochastic Markov process which includes three states, named state A, B and C. For sake of mathematical simplicity, we considered a discrete time branching process, whose time step unit is named βt. We suppose that, from a time step to the next, an A cell can die (rate Ad), stay the same (rate Ai), divide giving rise to two type B cells (rate As), or produce an asymmetric division in an B and a C cell (rate Aa). A B cell can die (rate Bd), stay the same (rate Bi), duplicate (rate Bs), give rise to a type C cell (rate Bt), or divide asymmetrically in an B and a C cell (rate Ba). Similarly, C cells can die, stay the same, divide (rates Cd, Ci, Cs). A number of other state changes could be considered. For simplicity we only include the above ones which are motivated on biological grounds. In our FACS data at day 3.5 the last populated subgroup is G6N, which points out that six division steps must have occurred since day 0. From that we derive βt = 14h, a value compatible with the known duration of the cell cycle. The ABC model can be analytically fully solved. The recursive relations of the average number of A, B and C cells, A(t), B(t) and C(t) can be derived from the Master Equation of the Markov process: A(t + 1) α (B(t + 1)) = (η δ C(t + 1) 0 0 A(t) β 0) (B(t)) C(t) σ γ where α = Ai ; β = 2Bs + Bi + Ba ; γ = 2Cs + Ci ; η = 2As + Aa ; σ = Bt + Ba ; δ = Aa . The eigenvalues α, β, γ of the above matrix give the longer time scale growth rates of the A, B and C populations respectively. The number composition of the different subpopulations, G0N, G1N, …, G6N can be analogously derived at any time, t, as a function of the microscopic parameters of the model. Fit of FACS data The initial condition considered in our fit corresponds to have all cells in state A, i.e., B(0) = T(0) = 0. The number of cells in the A population at day 0, A(0), is taken from the experiments. We refer here, for definiteness, to the case of the FACS data collected at day 3.5, where A(0) = 3.1 × 104. The model parameters are subject to the three normalization conditions of the probability rates in each single state. In the general case where asymmetric transitions are included, the ABC model has, thus, nine independent parameters. They are obtained by a Least Squares fit from the 13 measured subpopulations at day 3.5. More specifically, we find the minimum of the standard weighted squared distance: 6 2 5 GiN GiP D = ∑ ωiN ( ∗ − 1) + ∑ ωiP ( ∗ − 1) GiN GiP i=0 2 i=0 ∗ where GiN/P and GiN/P are respectively, the predicted and observed number of IL13- GFP± cells at day 3.5 having undergone i divisions. Finally, in the expression for D the weights ωiN/P are the relative fractions of the different observed populations: ∗ ∗ ωiN/P = GiN/P / ∑j GjN/P . Positive and Negative State specific gene We call A Pos, B Pos and C Pos, those genes that were specifically expressed only in state A, B and C respectively. We named A Neg, B Neg and C Neg those genes whose expression was repressed only in state A, B and C respectively. Genes were ranked with respect to the difference between the relative abundance in the positive state and the maximum relative abundance of the other states. The relative abundance of a given gene i in state j, si,j is: π π,π = π ππΎππ,π ⁄∑ π=πΈ,π΄,π π ππΎππ,π where RPKMij is the RPKM value of gene i in state j. In detail, we considered Positive only those genes whose expression is above their average expression only in one state (i.e, say si,j>1 only in one state), while Negative genes are those whose expression is below their average expression only in one state (i.e, say si,j<1 only in on state). Robustness of the fit with the ABC model In the main text we focused, in particular, on our FACS data at day 3.5 as they provide the broader and more precise measure of the different cell subpopulations. However, to asses the quality of our fit, we also considered independent FACS data at day 2 and day 3. Also in such cases the ABC model fits well the data. Importantly, the values of the parameters from the day 3.5 fit are, within errors, fully consistent with the values obtained by averaging the parameters of the fits across day 2, 3, 3.5. This is illustrated in the Figure S4c. Moreover, the fit of day 3.5 well reproduces day 2 and day 3 as shown in Figure S4b. Asymmetric divisions We also tested ABC model including asymmetric divisions. In particular, we considered a model (As-ABC) where asymmetric division (Aa and Ba, see Figure S4h) are added and a model (OA-ABC) where transitions Aa and Ba are take into account instead of As and Bt. The OA-ABC and A-ABC models do fit the day 3.5 and day 3 and day 2 FACS data, but the state population growth curves obtained with the OA-ABC and As-ABC are markedly different from the one obtained with the ABC Model (i.e., model with Aa = Ba = 0), since the A population is predicted to dominate at all large time scales (see Figure S4i and j). In facts, in all cases the OA-ABC fits give, for the longer time scale, a growth rate for state B larger than for state C: β = 1.3 > γ = 0.2 (average). More importantly, OA-ABC finds that transition from B to C are absent (Bt = Ba = 0). The As-ABC gives in average β = 1.2 > γ = 0.9, but it results γ < β only in fit of day 2 and day 3 showing instability in model predictions. Moreover, the asymmetric models give negligible asymmetric transition parameters in some cases suggesting that asymmetric transitions are absent with respect to the symmetric one, in particular the As-ABC finds the same parameters of those found by the ABC model at day 3.5 with asymmetric transition completely absent (Aa = Ba = 0). Statistical Model Selection: AIC and BIC To compare the quality of the fit of FACS data at day 3.5 with different ABC models, we computed the corresponding Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC) model selection parameters. Let LM be the log-likelihood of the parameter given the dataset, k the number of parameters and n the sample size. In this way AIC and BIC, for a model, are calculated through their definitions: AIC = 2k − 2LM BIC = −2LM + kln(n) In particular, we compared the AIC and BIC of the ABC model with As-ABC and OA-ABC models. AIC and BIC were calculated for all three cases of day 2, day 3 and day 3.5. In all cases the Symmetric ABC Model represents the minimum, while the OA-ABC results to be always the maximum. This suggest that the ABC model shows the best performances in terms of model fitting and complexity of the model compared with As-ABC and OA-ABC as shown in Figure S4k, which is the case of the fit of day 3.5. ERCC total reads The reduction in ERCC content from day 2 to days 3 and 4 can be ascribed to changes in cell sizes and total mRNA content due to cell cycle activation (rather than ERCC degradation, which is an alternative explanation). Cells at day 2 have a diameter of roughly 6 μM, while at day 3 and 4 they can reach up to 10 μM of diameter. The corresponding cell volume can then vary by up to a factor of 5 with the result of a significant dilution of the ERCC molecules as in the plot below.
