This volume contains 25 articles related to various areas of genetics, such as transgenerational epigenetic inheritance, mechanisms of neural crest migration, the Hippo signaling network and its biological functions, the Smc5/6 complex, H4-H4 histone chaperone pathways, piRNA-guided genomic defense, metabolic gene clusters in eukaryotes, genetic control of early cell lineages in the mammalian embryo, and single-cell RNA-sequencing strategies to dissect complex tissues.
NETs are a group of rare tumors of neural crest origin, most commonly found in the gastrointestinal or respiratory tracts, although they may also be found in the central nervous system, thyroid gland, skin, breast, colon, and urogenital system, including prostate cancer, among other locations.
Summary: TEHRAN (FNA)- A new study using mouse neural crest tissue reveals how primitive, undifferentiated cells choose their adult fate.
Hair and skin take on varying shades of red, brown, black and yellow due to the pigments produced by cells called melanocytes that originate embryonically from cells called neural crest cells, the same cells that can also give rise to neurons and their supporting glial cells.
CSPG2 antibody (Versican) is involved in the development of embryonic cell migration that is vital in heart formation and outlining of the neural crest path.
OSAKA, Japan, December 19, 2018 -- Researchers here revealed that culturing human induced pluripotent stem cells (hIPSCs) with different isoforms of the extracellular component laminin led to the creation of cells specific to different parts of the eye, including retinal, corneal, and neural crest cells.
This distinction is highly relevant because the prognosis of paragangliomas that arise from the neural crest is considerably better than that of neuroendocrine tumors of epithelial origin (2).
The protrusion forms in the dorsal wall of the aortic sac, which has a core derived from the second heart field, with only its outer layer derived from the cardiac neural crest,[7] which is defined as the neural crest residing between the otic placode and the third somite.
This cluster of cells is called the neural crest. Under normal developmental circumstances, as the embryo develops in the uterus, and eventually forms a fetus, the cells of the neural crest are sent around the body to form different tissues, including ear cartilage, the dentin that makes teeth, and melanocyte cells producing skin pigments.
The majority of patients were reported to have an underlying neural crest tumor (5).
Melanotic neuroectodermal tumor of infancy (MNTI) is a rare, rapidly growing, pigmented neoplasm of neural crest origin first described in 1918, (1) with slightly more than 500 reported cases to date.
