Haematological toxicity associated with cancer therapeutics is monitored by changes in blood cell count, whilst their primary effect is on proliferative progenitors in the bone marrow. Using observations in rat bone marrow and blood, we characterize a mathematical model which comprises cell proliferation and differentiation of the full haematopoietic phylogeny, with interacting feedback loops between lineages in homeostasis, as well as following carboplatin exposure. We accurately predicted the temporal dynamics of several mature cell types related to carboplatin-induced bone marrow toxicity and identified novel insights into haematopoiesis. Our model confirms a significant degree of plasticity within bone marrow cells, with the number and type of both early progenitors and circulating cells affecting cell balance, via feedback mechanisms, through fate decisions of the multi-potent progenitors. We also demonstrated cross-species translation of our predictions to patients, applying the same core model structure, and considering differences in drug-dependent and physiology-dependent parameters.
