65) It is noteworthy that the cells of intraosseous benign notochordal
cell tumor have the same immunophenotype as chordoma, but the former typically lacks a lobular architecture, fibrous bands, and myxoid matrix.
Thornwaldt's bursa or nasopharyngeal bursa is a recess in the midline of posterosuperior wall of nasopharynx, formed from notochordal
Chordomas are rare, slow-growing malignant yet locally aggressive osteolytic primary bone tumours derived from persistent notochordal
remnants that principally arise in the axial skeleton.
The origin of chondrocytes in the nucleus pulposus and histologic findings associated with the transition of a notochordal
nucleus pulposus to a fibrocartilaginous nucleus pulposus in intact rabbit intervertebral discs.
Persistence of canal on basilar part of clivus is a rare congenital defect of skull base representing an embryological remnant depicting the cephalic end of the notochord and corresponds to the course of the notochordal
canal in the basiocciput caudally.
At present at least 3 different NP cell types "chondrocytelike" cells (NP), notochordal
cells (NCs) and NP stem/ progenitor cells (NPPCs), have been identified within the NP.
9), and lack any sign of notochordal
pit, both features being diagnostic of Neobatrachia (GOMEZ et al.
Chordomas are rare, slow-growing tumours that originate from ectopic notochordal
remnants, found along the axial skeleton.
cell tumors: A comparative histological study of benign notochordal
cell tumors, classic chordomas, and notochordal
vestiges of fetal intervetebral discs.
10] Extensive work in animal models of gastrointestinal duplication has shown a very close relationship of this duplication with the presence of notochordal
and spinal abnormalities, such as spina bifida and split notochord syndrome.
1) The severity of the disorder correlates with the degree of notochordal
It is apparent that the origins of the most caudal elements in the Oikopleura tail are complex, and there are indications that at least two cell types, muscle and the t-cell, may derive from notochordal
