Author Summary. We present an in silico computational model of tumor growth and evolution according to the cancer stem cell hypothesis. Inheritable traits of cells may be genetically or epigenetically altered, and traits that confer increased fitness to the cell will be selected for on the population level.
The cancer stem cell model proposes that cancer stem cells, which form a sub-set of the tumor cells, are ultimately responsible for tumor ini-tiation, progression and recurrence. It is thought that through self-renewal and differentiation, cancer stem cells are respon-sible for the production of the various tumor cell types and contribute to tumor heterogeneity. Furthermore, according to this
clonal evolution and the stem cell hypothesis are the two theories that explain hallmarks of cancer the best5. For the purpose of this editorial our focus will be on the clonal evolution theory. The clonal evolution model of cancer is based on the premise of natural selection operating in any system with components of varying reproductive/survival potential6. Cancer clone evolution takes place
cancer stem cell model. The cancer stem cell model, also known as the Hierarchical Model proposes that tumors are hierarchically organized (CSCs lying at the apex (Fig. 3).)

Patient derived xenograft (PDX) is defined as a growth of patients’ tumor in the xenograft setting. The evolution of cancer model in animal has a century old history.

cancer stem cell (CSC) hypothesis [6, 7] also traces tumor origins to single mutated cells with unlimited proliferative potential, but in contrast to the clonal model, the cells possess stem cell qualities – evolution and population isolation example This means that while the evolution of a new species or a major transition (such as the evolution of birds from dinosaurs) may take millions of years, the evolution of a cell lineage into a cancerous form can take place on the scale of months or years.
The American Cancer Society has compiled an overview of how people have understood & described cancer throughout history, as well as treatment evolution.
Cancer stem cells are normal stem cells, with special ability to give rise to all types of cells found in a particular cancer sample, so making them able to generate tumors through the stem cell

Hypoxia is considered to be a major feature of the tumor microenvironment and is a potential contributor to the cancer stem cell (CSC) phenotype and its enhanced tumorigenicity. The acidic microenvironment around hypoxic cells is accompanied by the activation of a subset of proteases that contribute to metastasis. Because of aberrant angiogenesis and the inaccessibility of their locations

In the cancer stem cell model of tumors, CSC are defined as a small subset of malignant cells with the exclusive ability to self-renew and maintain the tumor. They can differentiate into a heteroge-neous mass of non-tumorigenic cancer cell types, which usually constitute the majority of the tumor [6].

Abstract. Genetic analyses have shaped much of our understanding of cancer. However, it is becoming increasingly clear that cancer cells display features of normal tissue organization, where cancer stem cells (CSCs) can drive tumor growth.
In several cases, such as in the case of CML, the cancer cell of origin is a stem/progenitor cell, and this explains the stem cell properties that allow the cancer stem cells to maintain the tumor mass.
Accumulation of mutations: cancer or molecule-to-man evolution?

Kreso A and Dick JE. Evolution of the cancer stem cell
In the cancer stem cell model of tumors, CSC are defined as a small subset of malignant cells with the exclusive ability to self-renew and maintain the tumor. They can differentiate into a heteroge-neous mass of non-tumorigenic cancer cell types, which usually constitute the majority of the tumor [6]. It is clear in this context that CSC, despite their ma – lignant phenotype, share common hall
Evolution of Tumor Model From Animal Model of Tumor to
The cancer stem cell model, According to the “stochastic model” (or “clonal evolution model”) every cancer cell in a tumor could gain the ability to self-renew and differentiate to the numerous and heterogeneous lineages of cancer cells that compromise a tumor These mutations could progressively accumulate and enhance the resistance and fitness of cells that allow them to

This means that while the evolution of a new species or a major transition (such as the evolution of birds from dinosaurs) may take millions of years, the evolution of a cell lineage into a cancerous form can take place on the scale of months or years.

Author Summary. We present an in silico computational model of tumor growth and evolution according to the cancer stem cell hypothesis. Inheritable traits of cells may be genetically or epigenetically altered, and traits that confer increased fitness to the cell will be selected for on the population level.

Accumulation of mutations: cancer or molecule-to-man evolution? Luke Kim Evolutionary biology claims that the accumulation of mutations is the driving force that gives rise to ‘higher’ living organisms. According to cancer biology, however, a major consequence of mutational accumulation is carcinogenesis (cancer initiation and progression), which inevitably leads to deleterious
