The cell cycle is a highly regulated process responsible for proper cell growth, development and differentiation. It combines DNA remodeling and chromosome separation to ensure uniform distribution of duplicated genetic material in daughter cells.

The phases of the cell cycle are divided into four successive phases, from silence (phase G0) to proliferation (phase G1, S, G2 and phase M) and return to phase G0. Eliminating the regulation of this process is considered a hallmark of cancer cell growth.

Flow Cytometry For Dna Analysis

Therefore, both academic and industrial drug discovery programs have heavily focused on drug development targeting cell cycle stages. Using advanced flow cytometry, researchers can quickly and accurately determine the different stages of the cell cycle.

Traditionally, cell cycle phases have been analyzed by evaluating DNA histograms generated by flow cytometry. This technology is fast and reproducible and can provide approximate cell numbers of G0 / G1, S, and G2 / M for a well-defined cell population.

However, cells G0 and G2 cannot be separated from cells G1 and M respectively. This limitation can be partially overcome by the achloride orange staining, giving a distinction from G1 to G0. Additionally, histogram analysis of cancer samples with anaphylactic populations can be difficult and sometimes impossible.

Cell Cycle Analysis Using Flow Cytometry

The cell cycle analysis of a flow cytometer relies on measuring the DNA content, which is usually analyzed on a linear scale because the differences in fluorescence are usually small. Flow cytometry software programs provide algorithms to accurately estimate the phases of the cell cycle.

Antigens associated with different cell proliferations and cycles have been described, allowing the evaluation of the expression of these antigens and the evaluation of cellular kinetic parameters.

Cyclins of proliferating cell nuclear antibodies (PCNAs) are mainly expressed in the S stage, which serves as a scaffold for DNA remodeling, DNA repair, chromatin remodeling, and epigenetic proteins.

PCNA expression was found to be associated with tumorigenesis, primarily with lethal levels, vascular invasion, distant metabolism, and survival. This antibody has been described as a biomarker of colorectal adenocarcinomas.

Areas Of Consideration For Flow Cytometry Cell Cycle Analysis

Cyclins are a group of proteins that control the progress of cells through the cell cycle by activating the cyclin-dependent enzyme kinase (CDK). The following are the most important cyclins involved in cellular cyclic processes.

Therefore, histone H3 pSer28 can be used as a specific marker for M-phase cells and can be integrated with other proliferation tools to further break down cell cycle components.
