Summary
Mammalian primordial germ cell (PGC) development involves crucial epigenetic reprogramming. This study explores chromatin changes, non-coding RNA interactions, and epitranscriptomic shifts during PGC development, highlighting research gaps in human germline epigenetics.
Area of Science:
- Developmental Biology
- Epigenetics
- Genomics
Background:
- Germline development exhibits significant inter-species variation.
- Mammalian primordial germ cell (PGC) development features conserved epigenetic reprogramming before sexual differentiation.
- Germline epigenetic alterations can affect subsequent generations, emphasizing the role of the non-coding genome.
Purpose of the Study:
- To detail key chromatin modifications during mammalian PGC development.
- To investigate the interplay between chromatin changes and non-coding RNA expression.
- To examine broader epitranscriptomic alterations in PGCs.
Main Methods:
- Review of existing literature on mammalian PGC epigenetics.
- Analysis of chromatin remodeling events.
- Integration of non-coding RNA expression data with epitranscriptomic profiles.

2.3K
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...

01:37Epigenetic Regulation
3.2K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

01:24Methods of Nuclear Reprogramming
1.9K
Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for...

2.3K
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

2.0K
Chromatin modification alters gene expression; therefore, scientists can add histone-modifying enzymes, histone variants, and chromatin remodeling complexes to somatic cells to aid reprogramming into pluripotent stem (iPS) cells.
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...

03:17Inheritance of Chromatin Structures
6.8K
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...
