The numbers of FXIIIa-positive cells were counted in the keloid, hypertrophic scar and mature scar, each of which was divided into fibrocollagenous area and superficial dermal area overlying the nodular lesion. 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.

They were also observed associated with epithelial structures in lung and kidney, but were only rarely observed in liver, thyroid, testis and spleen. Factor XIIIa Positive Control Slides suitable for immunohistochemistry (formalin-fixed, paraffin-embedded sections); find Sigma-Aldrich-251S MSDS, related peer-reviewed papers, technical documents, similar products & more at Sigma-Aldrich. 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.

Human XIII is a heterotetramer. Staining pattern is highly variable and nonspecific but the following stains may be positive: Factor XIIIa, CD163, CD10. Factor XIIIa is usually negative in DFSP. CD68 may highlight histiocytic cells (Patterson: Weedon's Skin Pathology, 5th Edition, 2020) FXIIIa positive cells in human skin represent a specific population of bone-marrow dermal dendritic cells, distinct from Langerhans cells, that share some features common to mononuc-lear phagocytes (monocyte/macrophages).

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. 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). The majority of cases, with the exception of 3 vertical growth-phase melanomas, had only slight (1-I-) increased staining (Fig.

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. Factor XIIIa-positive dendrocytes are almost absent in the reticular dermis and markedly reduced in number and size in the adventitial dermis. By contrast, the densities of vimentin-positive cells and CD34-positive cells were unremarkable. The biologic significance of this finding is unknown. Factor XIIIa Positive Control Slides , Product No. 251S, are available for immunohistochemistry (formalin-fixed, paraffin-embedded sections).

Factor XIIIa is a blood coagulation prototransglutaminase 1, which becomes an activated component of the final stages of the clotting cascade as a result of the interaction with thrombin and Ca 2+. Immunohistochemical analysis showed that factor XIIIa-positive histiocytic cells were distributed in the area without haemosiderin, but such cells were absent in the area with its deposition.
