Histopathology may reveal mature and immature elements arising from mesodermal, endodermal
and ectodermal cells.
The most important diagnostic characters (branch ridge patterns, stomatal patterns, and endodermal
patterns) can only be observed under high magnification and many of characters of E.
The scr mutant exhibit shoots agravitropism and defective radial pattern (missing endodermal
Changes in the morphology of the endodermal
cells were observed in vitro, including an increase in the size and a change in the shape from longitudinal to isodiametric (Figure 1).
MCNs may develop from endodermal
immature stroma or primary yolk sac cells implanted during embryogenesis.
Phytochromes inhibit hypocotyl negative gravitropism by regulating the development of endodermal
amyloplasts through phytochrome-interacting factors.
tumor resembling fetal lung: the optically clear nucleus is rich in biotin.
The thyroid diverticulum results from the invagination of a median endodermal
thickening in the floor of the primitive pharynx.

13) In addition to NSGCTs and HCC, however, elevated AFP-serum levels are also associated with pregnancy, primary hepatocellular carcinoma, endodermal
sinus tumors, and diseases such as ataxia telangiectasia, acute viral hepatitis, and cirrhosis.
It primarily accumulates in the lateral endodermal
sinus (yolk sac) tumor elements in testicular germ-cell tumors in adults: comparison of prospective and retrospective studies.
Teeth are usually assumed to be of ectodermal origin when found in the oral cavity, but of endodermal
origin when found on the branchial arches, corresponding to the assumed embryonic origin of the epithelium in each location.
Major tumours that secrete AFP are endodermal
sinus tumour (yolk sac carcinoma), neuroblastoma, hepatoblastoma, and hepatocellular carcinoma (77).
Various developmental malformations have been reported to be associated with osteopoikilosis, including: coarctation of the aorta, double ureter, pubertas praecox, urogenital defects, growth abnormalities, peptic ulcer, diabetes mellitus at the endodermal
strata level; arthritis, exostoses, osteitis condensans ilii, Klippel-Feil Syndrome, melorheostosis, spinal stenosis, cervical myelopathy, dacryocystitis, giant cell tumor, fibrous dysplasia, chondrosarcoma, osteosarcoma, synovial chondromatosis at the mesodermal level; facial abnormalities, hare lip, dental abnormalities, dermatofibrosis lenticularis disseminata, keloid formation, plantar and palmar keratomas at the ectodermal level (14-16).
