To maintain ploidy, unidirectional progression through the phases of the cell cycle (G1 → S → G2 → M → G1) is essential. To keep cells from regressing, the transitions of the mitotic cell ...

This sequential expression followed the phases of the traditional cell cycle: G0/G1 (the cell grows larger), S (the cell replicates its DNA), and G2/M (the cell prepares for division and then splits).

We report here the transcriptional profiling of the cell cycle on a genome-wide scale in ... matrix–associated functions in the G 2 cluster. At least some of these gene products, such as ...

Researchers observed an increase in both CXCR4 and CD5 levels as the cells progressed to later stages of the cell cycle, particularly in the S/G2/M phases.
