• Specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that arises from cells originating in the endodermal, mesodermal or ectodermal germ layer during embryogenesis.
• Immunohistochemistry stains positive against the proteins vimentin and S-100, and points to an ectodermal origin for the nodules.
• Ectoderm from the region of the dorsal lip of the blastopore of a developing salamander embryo was transplanted into another embryo and this "organizer" tissue “induced” the formation of a full secondary axis changing surrounding tissue in the original embryo from ectodermal to neural tissue.
• Michael John Berryman (born September 4, 1948) Berryman was born with hypohidrotic ectodermal dysplasia, a rare condition characterized by the absence of sweat glands, hair, and fingernails; his unusual physical appearance has allowed Berryman to make a career out of portraying characters in a number of cult films, horror films and B movies.
• Cranial to the primitive node of the embryonic primitive streak, ectodermal tissue thickens and flattens to become the neural plate.
• This invagination of ectodermal tissues is the progenitor to the later ameloblasts and enamel while the ectomesenchyme is responsible for the dental papilla and later odontoblasts.
• It begins as an ectodermal invagination at the roof of the stomodeum, which extends dorsally towards the developing brain.
• In human embryogenesis, the mammary ridge usually appears as a narrow, microscopic ectodermal thickening during the first seven weeks of pregnancy and grows caudally as a narrow, linear ridge.
• Unlike the larger tracheae which are derived of ectodermal stem cells, tracheoles do not molt with the insect.
• Positive test results may also be caused by malnutrition, adrenal insufficiency, glycogen storage diseases, hypothyroidism, hypoparathyroidism, nephrogenic diabetes insipidus, G6PD deficiency or ectodermal dysplasia.
• Pharyngeal pouches form on the endodermal side between the arches, and pharyngeal grooves (or clefts) form from the lateral ectodermal surface of the neck region to separate the arches.
• Lethal PPS is differentiated by microcephaly, corneal aplasia, ectropion, bony fusions, hypoplastic nose and absent thumbs, while PPS with Ectodermal Dysplasia is differentiated by woolly hair, brittle nails, ectodermal anomalies, and fissure of the sacral vertebrae.
• The condition may be caused by epidermolysis bullosa, specific teratogens, or intrauterine infections, or it may be caused by chromosomal abnormalities, ectodermal dysplasias, or other malformation syndromes.
• The groove gradually deepens as the neural folds become elevated, and ultimately the folds meet and coalesce in the middle line and convert the groove into a closed tube, the neural tube or canal, the ectodermal wall of which forms the rudiment of the nervous system.
• In this model, exclusively ectodermal cells are induced to become medial floor plate during gastrulation by prechordal mesoderm, possibly through Nodal signaling.
• Jadassohn–Lewandowsky syndrome: An ectodermal dysplasia characterized by onychogryposis, hyperkeratosis, leukoplakia, hyperhidrosis and pachyonychia congenita.
• In the wing bud in chick embryos, the AER becomes anatomically distinguishable at the late stage of development 18HH (corresponding to 3 day-old embryos), when the distal ectodermal cells of the bud acquire a columnar shape distinguishing them from the cuboidal ectoderm.
• In addition, abnormalities of ectodermal derivatives, neuroectodermal derivatives, and mesectodermal derivatives are often found.
• Amastia can be either isolated (the only medical condition) or comorbid with other syndromes, such as ectodermal dysplasia, Syndactyly (Poland's syndrome) and lipoatrophic diabetes.
• Most people with hypohidrotic ectodermal dysplasia have a reduced ability to sweat (hypohidrosis) because they have fewer sweat glands than normal or their sweat glands do not function properly.
