Environmentally Induced Transgenerational Epigenetic Reprogramming of Primordial Germ Cells and the Subsequent Germ Line
A number of environmental factors (e.g. toxicants) have been shown to promote the epigenetic transgenerational inheritance of disease and phenotypic variation. Transgenerational inheritance requires the germline transmission of altered epigenetic information between generations in the absence of direct environmental exposures. The primary periods for epigenetic programming of the germ line are ...
متن کاملEpigenetic reprogramming in mouse primordial germ cells
Genome-wide epigenetic reprogramming in mammalian germ cells, zygote and early embryos, plays a crucial role in regulating genome functions at critical stages of development. We show here that mouse primordial germ cells (PGCs) exhibit dynamic changes in epigenetic modifications between days 10.5 and 12.5 post coitum (dpc). First, contrary to previous suggestions, we show that PGCs do indeed ac...
متن کاملEpigenetic Reprogramming in the Mammalian Germ Line: Possible Effects by Endocrine Disruptors on Primordial Germ Cells
The present work provides a brief review about evidence obtained in the past years mainly in our laboratory using the mouse model, that germ cells and gonadal somatic cells may be direct target of endocrine disruptors (EDs) from very early stages of gonad formation. Since it is now known that epigenetic pathways are crucial for germ-line development and that EDs are also able to interfere with ...
متن کاملEpigenetic reprogramming of mesenchymal stem cells.
Mesenchymal stem cells (MSCs) are multipotent stem cells of mesodermal origin that can be isolated from various sources and induced into different cell types. Although MSCs possess immune privilege and are more easily obtained than embryonic stem cells, their propensity to tumorigenesis has not been fully explored. Epigenomic changes in DNA methylation and chromatin structure have been hypothes...
متن کاملForget the Parents: Epigenetic Reprogramming in Human Germ Cells
Epigenetic reprogramming in the germline resets genomic potential and erases epigenetic memory. Three studies by Gkountela et al., Guo et al., and Tang et al. analyze the transcriptional and epigenetic landscape of human primordial germ cells, revealing a unique transcriptional network and progressive and conserved global erasure of DNA methylation.
