Epithelialstroma interactions in the endometrium are known to be responsible for physiological functions and emergence of several pathologic lesions. Periglandular stromal cells act on endometrial cells in a paracrine manner through hormones. In this study, we immunohistochemically evaluated the expression of epithelialmesenchymal transition regulators (SNAIL/SLUG, TWIST, ZEB1), adhesion
Standardized, highthroughput RNA detection with microarray chips allows for the construction of genomewide databases for tissue specimens suitable for in silico electronic Northern blot (eNorthern) analysis of marker genes. We used the BioExpress database, which contains transcriptional profiles of normal and cancer samples, to examine two putative markers of cancer stroma: fibroblast

Pancreatic adenocarcinoma is a highly lethal disease that is histologically characterized by a dense desmoplastic reaction (DR) surrounding malignant epithelial cells. The DR is composed of extracellular matrix (ECM) proteins, fibroblasts, stellate cells, endothelial cells, immune cells, and neurons. Accumulating evidence indicates that the epithelial and stromal compartments interact to
Basosquamous carcinoma: While this tumour may also be considered in the differential diagnosis as within the umbrella of squamous cell carcinoma, the clinical and histological features more closely resemble basal cell carcinoma. The cellular morphology shows areas of large, pale squamoid cells, but lack therefore shows close resemblance to the metatypical type.

Stromal heterogeneity plays a significant role in cancer, influencing progression, outcome and response to therapy. Here, we discuss new technologies capable of reporting stromal regulation between normal, normal adjacent, and tumors in cancer tissues obtained from surgical pathology.

Struma ovarii is a teratoma of the ovaries that contains a large amount of thyroid tissue. Like the cervical thyroid gland, this ectopic thyroid tissue can become autonomous. We present a case of hyperthyroidism caused by thyroid tissue in a large ovarian cystic teratoma and provide detailed endocri
Frederick C. Koerner MD, in Diagnostic Problems in Breast Pathology, 2009. Characteristics of the Stroma. The stroma of hamartomas consists of any of a variety of mesenchymal tissues; often, several types of stroma coexist. Usually one sees dense fibrous connective tissue recapitulating the appearance and distribution of nonspecialized stroma and myxoid fibrous connective tissue surrounding
Mar 02, 2012#0183;#32;The aim of the study was to assess whether texture analysis is feasible for automated identification of epithelium and stroma in digitized tumor tissue microarrays (TMAs). Texture analysis based on local binary patterns (LBP) has previously been used successfully in applications such as face recognition and industrial machine vision. TMAs with tissue samples from 643 patients with colorectal

Pathology of Iris Atrophy Deepak P. Edward Michelle Y. Cho Pathologic changes in the iris and consequent clinical appearance may vary depending on the layer of the iris involved. Iris stromal atrophy causes stromal thinning and results in loss of iris crypts and the surface texture. Also, accompanying degeneration or loss of stromal melanocytes might
The mutual dependence of epithelium and stroma is not limited to embryonic development but also takes place in the adult. The cancer ecosystem. Descriptions of the participation of the host in the cancer ecosystem, comprising blood vessels, the fibroblastic stroma, and leucocytic reactions, can be found in textbooks of pathology 25.
Examinations of stroma of lymph nodes (50 patients) in lympho and reticulosarcomas revealed three types of alterations of the reticuline carcass: (1) diffuse destructive changes, (2) focal reticuline fibrosis against the background of destructive lesions, and (3) diffuse reticuline fibrosis. The fi

Mar 28, 2019#0183;#32;Stroma commonly refers to the fluid filled inner space of chloroplasts surrounding thylakoids and grana. Initially, the stroma was thought to simply provide support for the pigmented thylakoids. However it is now known that the stroma contains starch, chloroplast DNA and ribosomes, as well as all the enzymes required for lightindependent
Stroma also includes blood vessels that bring nutrients to the tissue and lymphatic channels that remove excess fluid and waste. The way stroma looks when viewed under the microscope changes in response to injury or or cancer. Desmoplasia is a word pathologists use to describe the look of the tissue after it has come in contact with cancer cells.
Accumulating evidence indicates that the epithelial and stromal compartments interact to enhance the aggressive nature of this disease. Pancreatic cancer cells release various factors that stimulate the stroma. Stromal cells, in turn, release mitogenic substances that stimulate tumor growth, invasion, and resistance to therapy.
