Questão 8

Questão
The "Cell-of-Origin" model of metastasis progresses as follows:
Responda
  • Normal epithelial cell (already has activated metastasis virulence genes due to its normal cellular differentiation program) > [series of mutations] > Primary tumour > [dissemination to a foreign microenvironment] > Metastatic colonisation
  • Normal epithelial cell > [series of mutations] > Primary tumour > [dissemination to a foreign microenvironment] > Viable partially metastasis-competent disseminated tumour cell > [mutations in metastasis virulence genes] > Metastatic colonisation
  • Normal epithelial cell > [series of mutations, including stochastic mutations in metastasis virulence genes] > Primary tumour > [dissemination to a foreign microenvironment] > Metastatic colonisation
  • Normal epithelial cell > [series of mutations] > Primary tumour > [dissemination to a foreign microenvironment] > [additional mutations] > Metastatic colonisation > [re-infiltration of the primary tumour by metastatic cells] > Primary tumour that has undergone self-seeding
  • Normal epithelial cell > [mutation] > Quasi-normal epithelial cell > [early dissemination to a foreign microenvironment] > Viable disseminated quasi-normal epithelial cell > [series of mutations, including mutations in metastasis virulence genes] > Metastatic colonisation

Questão 9

Questão
The "Partial-Competence" model of metastasis progresses as follows:
Responda

  • Normal epithelial cell > [series of mutations, including stochastic mutations in metastasis virulence genes] > Primary tumour > [dissemination to a foreign microenvironment] > Metastatic colonisation
  • Normal epithelial cell > [series of mutations] > Primary tumour > [dissemination to a foreign microenvironment] > [additional mutations] > Metastatic colonisation > [re-infiltration of the primary tumour by metastatic cells] > Primary tumour that has undergone self-seeding
  • Normal epithelial cell > [mutation] > Quasi-normal epithelial cell > [early dissemination to a foreign microenvironment] > Viable disseminated quasi-normal epithelial cell > [series of mutations, including mutations in metastasis virulence genes] > Metastatic colonisation
