Biological characteristics of cancer stem cells. Cancer stem cells possess both self‐renewal ability and multilineage differentiation potential, leading to the composition of intratumoral heterogeneity (a). Cancer stem cells possess the property of “robustness,” which is established by a combination of various phenotypes (b). Cancer stem cells are more resistant to various therapeutic interventions, leading to the generation of minimal residual disease (MRD) that is mainly composed by CSCs, and MRD is a major cause of recurrence and metastasis (c).
