... receptor (AR) and progesterone receptor (PR), a detailed analysis of the thecal glands was performed. Our ultrastructural studies revealed that the thecal glands of the quail ovary consist of 2 cell types, steroid-producing cells (SPCs) and enclosing cells (ENCs). The SPCs are large, light cells containing...

...Jüri Johannes Rumessen; Jean-Marie Vanderwinden; Alastair Hansen; Thomas Horn We studied the ultrastructure of interstitial cells in the subserosal/adventitial layer in human colon. An interstitial cell type with an ultrastructure intermediate between fibroblast-like cells (FLC) and interstitial...

.... Transmission electron microscopy was employed to investigate ultrastructure. Methylene blue staining, calcium-dependent fluorophores and confocal microscopy were used to identify ICLCs in live tissue. Methylene blue stained cells with morphology suggestive of ICLCs in the TD. Immunoreactivity localized...

..., histopathologic, ultrastructural, biomechanical and percent dry weight parameters. Treatment reduced signs of acute inflammation and strongly ameliorated clinical symptoms, structural organization and biomechanical properties (p < 0.05). Apparently, TC is effective in restoring the clinical, morphological...

... studies have shown that in the Japanese quail (Coturnix japonica) at least 5 glycoproteins are constituents of the IPVL (ZP1, ZP2, ZP3, ZP4, and ZPD). In this study, we investigated the spatiotemporal assembly pattern of the IPVL during folliculogenesis using immunohistochemical and ultrastructural...

...) in future clinical applications, it is essential to gain more insight into their differentiation capacity and to evaluate the tissues formed by these cells. In the present study, the morphological and ultrastructural characteristics of DPSC and UCSC induced towards osteogenic, adipogenic, and chondrogenic...

... of feather keratin is produced in forming feathers. The precise localization of the histidine-rich protein, either in feather barb and barbule cells and/or in supportive cells (sheath, barb vane ridge and cylindrical cells) is not known. The present ultrastructural autoradiographic study on developing...

...Annetrudi Kress; Lynne Selwood This study, based on 38 samples taken between the 16-cell stage on day 2.5 of gestation and the expanded 1.0-mm-diameter unilaminar blastocyst on day 6, describes the ultrastructural changes that occur in the conceptus of the marsupial Sminthopsis macroura in relation...

...Regula Wick; Annetrudi Kress Ultrastructural changes in the cervical epithelium related to the estrous cycle have been studied in the South American marsupial Monodelphis domestica . The two cervices protrude with prominent papillae into the sinus vaginalis. At times of simple columnar at others...

..., no significant differences were found. At the ultrastructural level, we found a decrease (p < 0.05) in the exocytotic profiles and the individual mean area of secretory granules of both gonadotropes in hamsters maintained under SP for 16 and 22 weeks. Exposure to short days resulted in a decline in serum...

...Regula Wick; Annetrudi Kress Ultrastructural changes in the endometrium associated with the oestrous cycle were studied in the South American marsupial Monodelphis domestica. The most conspicuous changes include the height and the differentiation of the uterine luminal and glandular epithelium...

.... These cells, respectively, represented the islet amylase and duct amylase intermediate cells. The ultrastructural survey was conducted on pancreatic tissue samples from normal and streptozotocin-diabetic mice and rats to prove the existence of these intermediate cells. Three morphologically distinct types...

... findings were also reported in human ADD as well as osteoarthritis of other joints. The purpose of this study was to further characterize these histopathological findings at the ultrastructural level. The right joint of 15 rabbits was exposed surgically and all discal attachments were severed except...
