Hybridoma cell lines were obtained from the fusion of NS-O myeloma cells with spleen cells of mice immunized with bovine fetal skeletal myosin. A stable hybridoma clone, BF-G6, produced immunoglobulin G1 k antibodies reacting specifically with embryonic-type myosin heavy chains present in fetal but not in neonatal or adult human skeletal muscle, as determined by enzyme immunoassay and immunoblot analysis. Fetal but not adult skeletal muscle fibers were stained by this monoclonal antibody in indirect immunofluorescence assays; smooth muscle cells and cardiac muscle cells, as well as non-muscle cells were also unreactive. Solid tumors of infants and children were tested for reactivity with BF-G6 by immunofluorescence and immunoperoxidase staining. Embryonic myosin heavy chain was expressed in rhabdomyosarcomas but not in other types of tumor, except for Wilms' tumor. Rhabdomyosarcoma cells isolated from a bone marrow metastasis and grown in vitro for several months were also labelled by BF-G6. Embryonic myosin heavy chain can thus be used as a specific differentiation marker of normal and neoplastic skeletal muscle tissue.

Rhabdomyosarcoma (RMS) cells express the polysialylated (PSA) form of the neural cell adhesion molecule (NCAM). During embryogenesis, PSA-NCAM is widespread and dynamically regulates embryonal developing processes, whereas postnatally, PSA-NCAM becomes restricted to a few regions of neural plasticity and regenerating neural tissues. Recently, PSA-NCAM has been shown to be a diagnostic and prognostic marker in adult patients with small cell lung cancer and multiple myeloma, both PSA-NCAM-expressing tumors. In this study, we determined the amount of PSA-NCAM in tumor specimens of nine children with different histologic types and clinical stages of RMS immunohistochemically, using the polysialic acid-specific MAb 735. In seven children, serum levels were investigated by an immunoluminescence assay using the same MAb. Patients with extensive disease showed strong staining of the tumor specimens, whereas patients with limited stages or after chemotherapy had distinctly a lesser amount of PSA-NCAM or almost no staining. Simultaneously, the serum levels were very high (up to 9-fold) in patients with extensive disease, whereas patients with limited disease or after successful therapy had normal serum levels. We conclude that PSA-NCAM expression is high in tumor specimens and serum of patients with advanced stages of RMS and decreases during successful therapy. PSA-NCAM might therefore serve as a marker for diagnosis and monitoring childhood RMS.

In this first article of a series of papers listing first case reports of animal diseases published since 2000, the following 19 cases of dog diseases are discussed: Blastomycotic granuloma involving the cranial vena cava. Congenital myocardial hamartoma. Discospondylitis: three cases caused respectively by Pseudomonas aeruginosa, Enterococcus faecalis and Staphylococcus epidermidis. Dystrophin deficient muscular dystrophy in a Labrador Retriever. Emphysematous prostatitis. Erythema multiforme major caused by a Parvovirus infection of keratinocytes. Hemochromatosis due to repeated blood transfusions. Intraspinal synovial cyst. Juvenile nephropathy in the Collie and the Irish Wolfhound. Primary cerebellar cortical degeneration (abiotrophy) in a Scottish terrier. Primary pulmonary artery chondrosarcoma. Renal dysplasia in a Bull Mastiff. Rhabdomyosarcoma (botryoid sarcoma) of the urinary bladder in a Maltese. Spinal mast cell tumor. Spongiform degeneration of the white matter in the central nervous system of Australian Cattle dog. Systemic pasteurellosis caused by Pasteurella canis. Thymic hemorrhage caused by dicumarol intoxication. Undimerized biclonal gammopathy with a single heavy chain class IgA in a dog with multiple myeloma. After a short introduction, the bibliographical data and the abstract of the author(s) and mostly some additional information derived from the article are given. The article will be regularly updated adding overlooked as well as new first reports.
