Expression of an individual gene can vary considerably among genetically identical cells because of stochastic fluctuations in transcription.

«We could show that even between seemingly identical cells, with the same morphology and the same genome, there are surprisingly pronounced differences on the level of the proteins,» Beck said.

Broadly speaking, however, analysis of transcriptional regulation at the single cell level has provided evidence for a strong stochastic element: genetically identical cells within the same environment show significant variation in molecular phenotype, in a fluctuating manner [24].

Sheltzer, who began his project in the laboratory of Dr. Angelika Amon at MIT and carried it to conclusion in his own research group at CSHL, placed two sets of otherwise identical cells in culture dishes, side by side.

«It's one set of genetically identical cells that are in communication with one another that have a sort of common purpose or at least can coordinate themselves to do something,» Volk explains.

Unisexual reproduction is a sexual cycle that can occur between genetically identical cells and, as we observed here, allows the introduction of limited de novo genetic diversity through meiosis.

«Single cell genomics can be applied to understand the heterogeneity of tumors, to explain how genetically identical cells may show distinct behavior, and to explore the vast, uncharacterized microbial landscape.

It reinforces the notion that tumors (and TNBC in particular) are not a homogeneous mass of identical cells, but a collection of distinct sub-populations of cells evolving somewhat independently of one another.

In mitosis, one cell divides to produce two genetically identical cells.

Thus, many tumors (especially solid tumors) are not a uniform mass of identical cells, but a heterogeneous mixture of different cell subpopulations.
