Mesodermal and spinal cord progenitors originate from common founder cells from which they segregate during development.
We believe this work not only has implications for the treatment of mitochondrial disease, but also adds to our knowledge regarding how mtDNA mutations segregate during development and are lost from certain cellular populations.
According to Weismann the somatoplasm developed and was influenced by the environment, whereas the germplasm was segregated early in development and was not susceptible to environmental influences.
In addition, because Hydra germ cells are not segregated early in development and instead arise from interstitial stem cells [47], FoxO expression in interstitial cells could help to minimize damage that would affect gametes.
And however many units are built, they must be blended seamlessly into the development — not segregated and concentrated in miniature poverty zones.
In lower organisms the germ cell lineage is designated after the first cleavage; however, in mammals the germ cell lineage is segregated relatively late in development, peri-gastrulation [29].
Wide-ranging political, socioeconomic, and discriminatory forces coupled with spatial patterns of industrialization and development have segregated people of color, particularly African Americans, into communities with some of the highest indices of urban poverty and material deprivation (Morello-Frosch and Jesdale 2006; Schultz et al. 2002; Williams and Collins 2004).
Wide-ranging and complex political and socioeconomic forces, coupled with patterns of industrialization and development, have segregated people of color, particularly African Americans, into neighborhoods with some of the highest indices of urban poverty and deprivation (Peet 1984; Schultz et al. 2002; Walker 1985; Williams and Collins 2001, 2004).
In our patient cohort, reduced mitochondrial LETM1 expression seems to segregate with seizure development.
Our work describes for the first time a set of mitochondrial phenotypes in WHS-patient-derived LCLs that also segregate with seizure development in the small cohort examined.
