Figure 4From: Modeling invasion of metastasizing cancer cells to bone marrow utilizing ecological principlesCompetition among two species. The red (dash) line indicates the relative superior species (cancer cells); the green (solid) line indicates the relative inferior species (HSC). Superior species (cancer cells) can displace 90% of the inferior species (HSC). Inferior species (HSC) can displace 10% of the superior species (cancer cells). (A) Superior species (cancer cells) has colonization rate β1 = 0.2, mortality rate μ1 = 0.1 time-1 , and initial density = 0.0001. Inferior species (HSC) has colonization rate β2 = 0.8, mortality rate μ2 = 0.1 time-1 , and initial density = 0.5. (B) The superior species (cancer cells) has initial density = 0.01, and the inferior species (HSC) has initial density = 0.85; all other conditions remained the same as in (A). (C) The inferior species (HSC) has initial density = 0.84 and colonization rate β1 = 0.61 time-1 ; all other conditions remained the same as in (A).Back to article page
