Sketch of the retrotracing of IPN S-labeled cells at t2 back to IPP S phase at t1. Double labeled cells (magenta-cyan horizontal segment), whose age at t2 belongs to \(\left [T^{IPN}_{G1}, T^{IPN}_{G1}+T^{IPN}_{S}\right ]\), have initiated an IPN cycle in the time interval \(\left [t_{2}-\left (T^{IPN}_{G1}+T^{IPN}_{S}\right),t_{2}-T^{IPN}_{G1}\right ]\) (navy vertical segment) instantaneously after exiting mitosis of a former IPP cycle, when they had reached age \(T^{IPP}_{C}\) (darkgreen vertical segment). In addition, they had to be in S phase of the IPP cycle at t1, with their age belonging to \(\left [T^{IPP}_{G1}, T^{IPP}_{G1}+T^{IPP}_{S}\right ]\). Production of additional cells through division is not explicitly figured here
