Supporting: 1, Mentioning: 23 - Immunohistochemical staining for factor XIIIa, a transglutaminase, revealed a variety of positively stained cells in human fetal tissues. Factor XIIIa-positive cells were most numerous in the dermis and connective tissues. Numerous large, stellate cells in placental villi, decidua, and chorionic membranes also expressed factor XIIIa at 7-9 weeks gestational age

However, at least a subset of dermal Factor XIIIa-positive dendrocytes present at the periphery and inside epithelial neoplasms are an heterogeneous group of cells. They are subsets of mesenchymal cells, cancer-associated macrophages Factor XIIIa-positive cells were most numerous in the dermis and connective tissues. Numerous large, stellate cells in placental villi, decidua, and chorionic membranes also expressed factor XIIIa at 7-9 weeks gestational age, before the onset of fetal hematopoiesis. Anti- Factor XIIIa has been found to be useful in differentiating between dermatofibroma (90% positive) and desmoplastic malignant melanoma (negative). Factor XIIIa positivity is also seen in capillary hemagioblastoma, hemangioendothelioma, hemangiopericytoma, xanthogranuloma, xanthoma, hepatocellular carcinoma, glomus tumor , and meningioma.

They are subsets of mesenchymal cells, cancer-associated macrophages and antigen-presenting cells. Factor XIIIa-positive dendrocytes present at the periphery and inside epithelial neoplasms are an heterogeneous group of cells. They are subsets of mesenchymal cells, cancer-associated macrophages and antigen-presenting cells. Factor XIIIa positive control slides are intended for use as positive controls for immunohistochemical (IHC) staining using an anti-Factor XIIIa antibody. Physical form Paraffin embedded tissue section mounted on microscope slide Factor XIIIa-positive cells were most numerous in the dermis and connective tissues. Numerous large, stellate cells in placental villi, decidua, and chorionic membranes also expressed factor XIIIa at 7–9 weeks gestational age, before the onset of fetal hematopoiesis.

Academic Article Overview abstract . The histogenesis of Kaposi's sarcoma (KS) has been the subject of controversy, much of which has centered around whether the spindle cells of KS are derived from vascular endothelium or from lymphatics. Platelet factor XIII is comprised only of 2 A subunits, which are identical to those of plasma origin.

DFSP is diffusely CD34 positive and Factor XIIIa negative, whereas dermatofibromas (and additional fibrohistiocytic tumor types other than DFSP) show the converse of this profile or only limited CD34 reactivity at the advancing edge of the lesion. 402 At a molecular level, all forms of DFSP are characterized by a balanced translocation between the collagen type 1-alpha1 gene (COL1A1) and the platelet-derived growth factor-beta gene (PDGFB).

Factor XIIIa positivity is also seen in capillary hemagioblastoma, hemangioendothelioma, hemangiopericytoma, xanthogranuloma, xanthoma, hepatocellular carcinoma, glomus tumor , and meningioma. Before you can use immunostains to help recognize different tumors and diseases in dermpath, you must first understand how they stain the normal structures i Factor Xiiia staining Four of 10 (40%) compound nevi, 9 of 20 (45%) radial growth-phase melanomas, and 12 of 20 (60%) vertical growth-phase melanomas showed an increase in factor Xllla staining of DDCs (Ta-ble 1).

Factor XIII or fibrin stabilizing factor is a zymogen found from the blood of humans and some other animals. It is activated by thrombin to factor XIIIa. XIIIa is an enzyme of the blood coagulation system that crosslinks fibrin. Deficiency of XIII worsens clot stability and increases bleeding tendency. Human XIII is a heterotetramer.

Involvement in disease. By dual-labeling immunofluorescence and confocal microscopy, GPIb alpha-positive cells within the dermal interstitium are demonstrated to represent factor XIIIa-positive dermal dendrocytes. In organ cultures of neonatal human foreskin, mast cell degranulation induced by either substance P or compound 48/80 resulted in transiently increased GPIb alpha expression by dermal dendrocytes. Newcomer Supply Factor XIIIa (fibrin stabilizing factor) Control Slides are for the positive immunohistochemical staining of Factor XIIIa, a blood coagulation enzyme that crosslinks fibrin.

Factor XIIIa positive cells in human skin represent a specific population of bone marrow dermal dendritic cells, distinct from Langerhans cells which share some features common to mononuclear phagocytes. Dendritic, factor XIIIa positive cells were observed in all tissues studied, but were most numerous in skin and mucosal tissues (gastrointestinal tract, bladder). They were also observed associated with epithelial structures in lung and kidney, but were only rarely observed in liver, thyroid, testis and spleen. Factor XIII is activated by thrombin and calcium ion to a transglutaminase that catalyzes the formation of gamma-glutamyl-epsilon-lysine cross-links between fibrin chains, thus stabilizing the fibrin clot. Also cross-link alpha-2-plasmin inhibitor, or fibronectin, to the alpha chains of fibrin. Involvement in disease. By dual-labeling immunofluorescence and confocal microscopy, GPIb alpha-positive cells within the dermal interstitium are demonstrated to represent factor XIIIa-positive dermal dendrocytes.
