Margin status, a major prognostic parameter in oral cancer, was analyzed vis-à-vis the histopathologic parameters of risk scores and stromal myofibroblasts. Specimens of tongue carcinoma (n = 50) were submitted to a risk score assignment consisting of the worst pattern of invasion, lymphocytic infiltration, and perineural invasion. Frequency of stromal myofibroblasts (alpha-smooth muscle actin stain) was assessed. A triple immunostaining assay with E-cadherin, Ki-67 and alpha-smooth muscle actin was used to identify carcinoma cells undergoing epithelial-mesenchymal transition. Margins were considered 'clean' if the tumor was >or=5 mm away from them. Patients

Fibrotic focus is a pivotal morphofunctional unit in developing fibrosis in various tissues. For most fibrotic diseases, including progressive forms, the foci are considered unable to remodel and contribute to the worsening of prognosis. Unfortunately, the dynamics of the fibrotic focus formation and resolution remains understudied.

The maternal-fetal interface has long been considered as a frontier for an evolutionary arms race due to the close juxtaposition of genetically distinct tissues. In hemochorial species with deep placental invasion, including in humans, maternal stroma prepares its defenses against deep trophoblast invasion by decidualization, a differentiation process characterized by increased stromal cell matrix production, and contractile force generation. Decidualization has evolved from an ancestral wound healing response of fibroblast activation by the endometrial stroma.

Sulfur mustard gas (SM), an alkylating and vesicating agent, has been used frequently in many wars and conflicts. SM exposure to the eye results in several corneal abnormalities including scar/fibrosis formation. However, molecular mechanism for SM induced corneal fibrosis development is poorly understood.

Objective: To evaluate the representation and localization of FAP-positive activated stromal cells depending on the severity of fibrotic changes in tissues of patients with a confirmed diagnosis of COVID-19.
Material And Methods: 20 autopsy observations of patients who died from COVID-19 were studied. Immunohistochemical studies were performed using antibodies to CD90, FAP and aSMA and a dual imaging system.

Background: Adipose tissue provides an abundant source of stromal vascular fraction (SVF) cells for immediate administration. It can also give rise to many multipotent adipose-derived stromal cells. SVF is the population of cells obtained from mechanical or enzymatic digestion of lipoaspirate with no necessity for cell culture or expansion.
