The salient feature of one-cell-thick epithelia is their en face view, which reveals the polygonal cross section of the close-packed prismatic cells. The physical mechanisms that shape these tissues were hitherto explored using theories based on cell proliferation, which were either entirely
BACKGROUND
The ducts of eccrine glands may give rise to intra-epidermal, confluent epithelial and intra-dermal adenomas known as hidroacanthoma simplex, eccrine poroma, and dermal duct tumor, respectively. An apocrine and sebaceous counterpart of the eccrine poroma has been described by several
OBJECTIVE
To investigate the role of human Wnt7b gene in rat chondrocyte degeneration.
METHODS
Wnt7b gene obtained by PCR was cloned to PCDH-GFP. 293ft cell line was transfected with PCDH-GFP and PCDH-Wnt7b, and the supernatant and transfected cells were collected. The expression level of Wnt7b in
Thymic cysts with pseudoepitheliomatous hyperplasia are described in a 7-month-old female American Eskimo Dog that died of complications from brodifacoum poisoning. Grossly, there was hemothorax with marked cranial mediastinal hemorrhage. Histologically, thymic lobules were expanded and distorted by
OBJECTIVE
We report a case of Terrien's marginal degeneration (TMD) with a unilaterally typical narrow band of peripheral corneal stroma thinning, accompanied by the presence of an unusual network of opacities diffusing throughout the anterior stroma layers.
METHODS
A 43-year-old woman presented
Globes were obtained post mortem from a 75-year-old patient who had both corneal posterior crocodile shagreen and polymorphic amyloid degeneration. The crocodile shagreen was typified by grayish, polygonal opacities with indistinct edges and separated by clear lines. The cloudy area involved the
OBJECTIVE
To explore a new method for the pre-degeneration of peripheral nerve in vitro for obtaining many effective Schwann cells so as to provide a large number of seed cells for the research and application of tissue engineered nerves.
METHODS
The bone marrow derived cells (BMDCs) from transgenic
Nodular granular muscle degeneration (NGMD) of the appendix is a rare histologic curiosity characterized by distinctive nests of polygonal epithelioid cells with abundant pale-pink eosinophilic granular cytoplasm, mostly distributed in the inner layer of the muscularis propria or submucosa of the
Lipofuscin and melanolipofuscin organelles in retinal pigment epithelium (RPE) cells are signal sources for clinical fundus autofluorescence (AF). To elucidate the subcellular basis of AF imaging, we identified, characterized, and quantified the frequency of RPE morphology and AF The retinal pigment epithelium (RPE) is a unique epithelium, with major roles which are essential in the visual cycle and homeostasis of the outer retina. The RPE is a monolayer of polygonal and pigmented cells strategically placed between the neuroretina and Bruch membrane, adjacent to the
OBJECTIVE
To determine the cellular origin and the vascular endothelial growth factor (VEGF) immunoreactivity of the nonvascular stromal cells in surgically excised age-related macular degeneration (ARMD)-associated choroidal neovascular membranes (CNVMs).
METHODS
Immunohistochemical analysis was
BACKGROUND
In recent years, nucleus pulposus cell (NPC) transplantation has been used to treat intervertebral disc degeneration (IDD); however, the degenerative nature of NPCs influences its effectiveness. Nucleus pulposus-derived stem cells (NPSCs), which are self-renewing, have high expansion
BACKGROUND
Barium radiographic studies have suggested the importance of evaluating areae gastricae pattern for the diagnosis of gastritis. Significance of endoscopic appearance of areae gastricae in the diagnosis of chronic atrophic fundic gastritis (CAFG) was investigated by image-enhanced
Dermatofibroma (DF) or cutaneous fibrous histiocytoma is a common benign skin tumor that exhibits multiple, distinct histologic variants. Although clear cell DF has been described in the literature, balloon cell degeneration causing a clear cell DF phenotype has been not been reported to date.
Epithelial endometrial cells were isolated from normal and ovariectomized adult rats. The procedure involves successively (1) perfusion of the uterine vasculature with calcium-free Hanks' solution, (2) perfusion with 0.05% collagenase and 0.1% hyaluronidase in calcium-free Hanks' solution, (3)
