Bone marrow stem cells develop into hematopoietic and mesenchymal lineages but have not been known to participate in production of hepatocytes, biliary cells, or oval cells during liver regeneration. Cross-sex or cross-strain bone marrow and whole liver transplantation were used to trace the origin of the repopulating liver cells. Transplanted rats were(More)
Lectin binding patterns in the salivary glands of mice and rats were compared among specimens treated with 9 kinds of fixatives and then individually subjected to 10 kinds of lectin staining. Formalin-fixed sections showed positive lectin binding with fine granular materials in the GCT cells, and alcohol- or acetone-fixed sections revealed vacuolated(More)
Keratin proteins were immunohistochemically demonstrated in different parts of the oral epithelium. Keratin staining in the squamous-cell epithelium was restricted to the spinous and granular cell layers, with a comparatively low reaction in the basal layer cells and none in the superficial cornified layer. In comparing the keratin staining levels, those in(More)
The immunohistochemical localization of keratins in the oral epithelia of several mammals was investigated using the monoclonal antibodies to keratins, PKK1 (41–56 kilodaltons) and KL1 (55–57 kilodaltons). The staining patterns obtained in different locations of the oral mucosa and of the skin epidermis were compared. In the papillae on the dorsal surface(More)
Immunohistochemical demonstration of S-100 protein in Langerhans cells (LCs) was made in odontogenic epithelial tumours (71 cases), radicular cysts (40 cases), follicular cysts (28 cases), odontogenic keratocysts (11 cases), primordial cysts (7 cases) and fissual cysts (6 cases). With the use of polyclonal antiserum against S-100 protein, positive LCs,(More)
Immunohistochemical demonstration of carcinoembryonic antigen (CEA) was reported in normal salivary glands and in pathologic lesions. Staining patterns of CEA and nonspecific cross-reacting antigen-absorbed CEA (NCAa-CEA) were compared. Normal salivary glands disclosed positive staining by CEA on border and luminal sides of acinar cells and occasionally in(More)
Immunohistochemical identification of alpha 1-antitrypsin (alpha 1-AT) and alpha 1-antichymotrypsin (alpha 1-ACh) in pleomorphic adenomas of salivary glands is reported in order to compare their distribution profiles with those of lysozyme and lactoferrin, already described elsewhere. Normal salivary glands indicated positive alpha 1-AT staining in ductal(More)
Immunohistochemical identification of factor VIII related antigen (F VIII RAG) filament proteins (actin, myosin, filamin, vimentin and desmin) and lectin binding patterns of Con A, PNA, SBA, WGA, RCA-1, UEA-1 and DBA in the endothelial cells and the musclar layers of haemangiomas and normal blood vessels are reported, using paraffin sections with the HRP(More)
Immunohistochemical demonstration of epidermal growth factor (EGF) and nerve growth factor (NGF) was made during chemical carcinogenesis in the mouse submandibular gland. The granular convoluted tubule cells in the normal male submandibular gland contained larger amounts of EGF and NGF than in the female. The initial phase and early stages in chemical(More)
