For Helicobacter pylori, a pathogenic bacterium that colonizes over 40 percent of the world population and is associated with gastric cancer, the team discovered that epigenetic heterogeneity can quickly emerge as a single cell divides, and different subpopulations with distinct methylation patterns have distinct gene expressions patterns.

As the animal moves, different subpopulations of these cells become active depending on distance and direction, creating an internal map of its trajectory.

Cancers contain genetically different subpopulations of cells, called subclones.

Apart from correlational studies that link MDI data to other measures, future studies also need to explore to what extent the MDI measures constructs similarly for different subpopulations.

As we noted earlier, when studying whether a preventive intervention works differently for different subpopulations, most investigators have focused only on general population characteristics such as gender or ethnicity.

He adds that the concept seeks to balance relationships both among different species and among subpopulations of a given species such as age groups, gender groups or regional schools.

The samples were then analyzed with a technique called polymerase chain reaction (PCR), used to amplify specific nuclear «microsatellites» for statistically measuring gene flow between the different populations and subpopulations located in the western South Atlantic (Breeding Stock A) and the eastern South Atlantic and Indian Ocean populations (Breeding Stocks B and C, and the Arabian Sea humpback whale population, respectively).

The authors point out that the findings support previous observations of individual male whales moving between populations in different ocean basins, and that subpopulations from both regions could share the same feeding ground in Antarctic waters.

In the past several years there has been growing evidence supporting this notion, revealing subpopulations of cells representing different arms of the immune system, as potential regulators of the immune system.

The commentary highlights the possible fundamentally different and even opposing functions of intestinal fibroblast subpopulations in regulating inflammation and tumour formation and underscores the need to further characterize these cells to reveal new mechanisms underlying pathogenesis of chronic inflammation and cancer.

In particular, diversity of the nuclear genome is unlikely to be reciprocally monophyletic among subpopulations, a phenomenon called incomplete lineage sorting, which results in support for different topologies across loci (27).

We show that subpopulations of human astrocytes, generated by activation of different signaling pathways in the same population of human glial precursor cells, have markedly different effects when transplanted into the injured spinal cord.

Interestingly, while these subpopulations are equivalently and clonally interconvertible under self - renewing conditions, when induced to differentiate both in vivo and in vitro they exhibit different behaviours.

While it has been demonstrated previously that more differentiated cells demonstrate a lower reprogramming efficiency [11] and different somatic cell types possess differential reprogramming ability [12], [13], no study to date, to our knowledge, has identified subpopulations of cells within a primary cell population possessing differential reprogramming potential.

In contrast to germline variants, somatic variants are not propagated to the whole individual but to a subpopulation of cells in the body, with the final consequence that adult human tissues are a mosaic of genetically different cells.

Table below the Figure indicates the proportion of cells in each subpopulation for the different cell lines.

These inconsistencies likely arise because of two reasons: (a) the literature is sparse with individual studies covering distinct time periods and examining distinct subpopulations and (b) the various studies use different operational definitions for age heterogamy (Drefahl, 2010; Rose & Benjamin, 1971; Shehan et al., 1991).

It may also be of special interest to study clinical subpopulations known to have different affective experiences than the average population.
