Abstract AIMS Paediatric high-grade glioma (HGG) and ependymoma (EPN) are two devastating malignant tumours of the central nervous system that unfortunately carry a poor prognosis. As R loops known source genomic instability in eukaryotic cells have previously been revealed to undergo m6A RNA methylation, we sought investigate potential link between methylation relation pathogenesis paediatric ...

The fine structure of human (1-4) and other mammalian (3, 5-12) gastric endocrine cells ("argyrophile," "argentaffin," "enterochromaffin," "pale," "clear," "endocrine-like") has been described . This report describes an unusual morphological and cytochernical relationship observed between human gastric endocrine cells and other types of gastric epithelial cells . The endocrine cells are frequen...

Acute lymphoblastic leukaemia (ALL) is a malignant transformation of a clone of cells from lymphoid progenitor cells. The majority of cases are of B-cell origin but it can also arise from T-cell precursors. Lymphoid precursors proliferate and replace the normal cells of the bone marrow and blasts spill into the peripheral circulation. It can be distinguished from other malignancies of lymphoid ...

We recently isolated stem cells derived from the brain of a bovine fetus, utilizing a particular mechanical separation method. After improving our experimental conditions, we obtained neural stem cells using an optimized culture medium system. The cells were expanded, established in continuous cell culture and used for immunofluorescence cytochemistry. RT-PCR showed that embryonic neural stem c...

Chicken embryo lethal orphan (CELO) virus replication studies in adult hamster kidney and green monkey kidney cell cultures by means of infectivity, cytochemistry, and fluorescent-antibody techniques indicated that replication in hamster kidney cells was limited to the production of neoantigen. Production of virus in green monkey kidney cells was limited but appeared to exceed the production of...

The present (Wiesbaden) classification of gut endocrine cells relies mainly on ultrastructure and the results of silver impregnation. Correlation with hormone production requires parallel immunology but conventional immune cytochemistry is, in most cases, difficult or at present impossible. The serial, semithin-thin-section technique offers an alternative, which provides absolute correlation be...
