Role of stem cells in cancer therapy and cancer stem cells a review Biology Diagrams Pluripotency is also linked with cell-cycle regulation because studies in mouse ESCs (mESCs) have shown that their pluripotent status is associated with a specific cell-cycle profile characterized by a shortened G1 phase and the lack of G1 checkpoint regulation (Coronado et al., 2013; Savatier et al., 1996).In conventional cells, cyclin D1-3 are expressed in G1 phase and control the activity
In addition to the properties of self-renewal and multipotency, cancer stem cells share the characteristics of their distinct cell cycle status with somatic stem cells. Cancer stem cells (CSCs) are maintained in a quiescent state with this characteristic conferring resistance to anticancer therapies that target dividing cells. Elucidation of Cell cycle regulation depends on phase-specific transcriptions of cell cycle genes. The alterations of cell cycle genes can predispose normal cells to have a cancerous phenotype. Indeed, several mechanisms underlying the deregulation of the cell cycle have been identified in different types of cancer. The cell-cycle state of stem cells determines cell fate propensity.

What is the Cell Cycle and How Is It Related to Cancer? Biology Diagrams
Cancer stem cells (CSCs), a small subset of cells in tumors that are characterized by self-renewal and continuous proliferation, lead to tumorigenesis, metastasis, and maintain tumor heterogeneity. The core cell cycle machinery operating in the cell nucleus orchestrates cell division. The key components of this machinery are proteins called cyclins that bind, activate and provide substrate specificity to their associated catalytic partners, the cyclin-dependent kinases (CDKs) 1-4.Cell cycle progression can be divided into four phases: gap 1 (G1), DNA synthesis (S), gap 2 (G2) and
The role of cancer stem cells in metastasis, recurrence, and resistance to conventional therapies is significant. Addressing these cells could potentially decrease cancer reoccurrences and mortality rates. TET1, a crucial gene involved in stem cell self-renewal and potency, may also play a part in cancer stem cells, which warrants further research. Cancer is a group of diseases in which cells divide continuously and excessively. Cell division is tightly regulated by multiple evolutionarily conserved cell cycle control mechanisms, to ensure The duration of the cell cycle varies from one cell type to another. Most human cells complete the cycle in about 24 hours. Fast-growing cells, like those in the lining of the intestine, may complete it in just 9 or 10 hours, while liver cells take more than a year and neuronal cells take many years.
