| Neither ectodermal nor endodermal components were identified in the sections examined. |
|
| The tumor demonstrated predominantly mature ectodermal, mesodermal, and endodermal elements. |
|
| Several teeth may be absent in disorders such as Down's syndrome and ectodermal dysplasia. |
|
| A mesenchymal signal triggers an ectodermal cell to proliferate and the cells grow downward to form a hair germ. |
|
| The apical ectodermal ridge consists of closely packed columnar epithelial cells, which are linked by extensive gap junctions. |
|
| The cnidarian homolog of the nervous system is a nerve net that is largely ectodermal. |
|
| Clouston syndrome is an hidrotic form of ectodermal dysplasia, inherited as an autosomal dominant trait with high penetrance. |
|
| The simple ectodermal epithelium of the anterior metatarsal region produces the suprabasal peridermal layer around 6 days of development. |
|
| As the neural tube closes, the ectodermal cells continue to grow and divide very rapidly. |
|
| They are made up predominantly of ectodermal components and have a large cystic component. |
|
| The term iteration is used to denote processes that result in both metameric segments and repeated ectodermal skeletal structures. |
|
| Most cnidarian muscles, however, are thin sheets at the base of ectodermal and endodermal layers. |
|
| Hidrotic ectodermal dysplasia, also know as Clouston syndrome, is an autosomal dominant disorder. |
|
| The most interesting and most perplexing question is how ectodermal glands can be derived from what has been thought to be endodermal and mesodermal derivatives. |
|
| In most polychaetes, the ectodermal and mesodermal derivatives of the growth zone become incorporated into segmental tissues in an anterior-posterior sequence. |
|
| A slight invagination of the ectoderm occurs, and a cloacal membrane forms, separating the ectodermal invagination from the gut cavity. |
|
| However, some lesions are amelanotic and others demonstrate features similar to other malignant neoplasms of ectodermal, mesodermal, or hemopoietic origin. |
|
| The bud is also encased in ectodermal epidermis. |
|
| This part of the ectodermal layer thickens and becomes the neural plate, whose edges rise as neural folds that converge toward the midline, fuse together, and form the neural tube. |
|
| It is characterized by ectrodactyly, ectodermal dysplasia, and with or without clefting anomalies. |
|
|
|
| Analysis of the genetic pathway leading to formation of ectopic apical ectodermal ridges in mouse Engrailed-1 mutant limbs. |
|
| Cicatrising conjunctivitis with anti-basement membrane autoantibodies in ectodermal dysplasia. |
|
| It consists of five paired mesodermic arches, each separated by an endodermal pouch and an ectodermal cleft. |
|
| The phakomatoses are a group of congenital malformations of the ectodermal tissues. |
|
| Absent meibomian glands in the ectrodactyly, ectodermal dysplasia, cleft lippalate syndrome. |
|
| Soon after the appearance of forelimbs, most pond-dwelling salamanders develop an ectodermal projection known as a balancer on each side of the head. |
|
| Tests showed that MenSCs could differentiate into adipogenic, chondrogenic, osteogenic, ectodermal, mesodermal, cardiogenic, and neural cell lineages. |
|
| Ingression of ectodermal cells from the area between the velar lobes establishes the cerebral ganglia and similar ingressions produce the other ganglia. |
|
| The inner cell mass of the EB consists of mesodermal and ectodermal cells, as shown by positive immunofluorescence with MF20 and keratin-18 antibodies, respectively. |
|
| Gorlin-Goltz syndrome was first reported in 1894, but described by Gorlin and Goltz in 1960 as a distinct entity consisting of ectodermal and mesodermal abnormalities. |
|
| The extent of this DNA methylation was similar in endodermal, mesodermal, and ectodermal tissues, indicating that genistein acts during early embryonic development. |
