  • [ 2 , 3 ] About 3-10% of pure germ cell tumors are embryonal carcinomas, and embryonal carcinomas are present in more than 80% of mixed germ cell tumors. (medscape.com)
  • [ 8 ] The most accepted theory on the development of germ cell tumors involves an initiating event that causes fetal gonocytes to undergo abnormal cell division. (medscape.com)
  • As with other germ cell tumors, with the exception of spermatocytic seminoma , embryonal carcinomas are believed to originate from intratubular malignant germ cells. (medscape.com)
  • Germ cell tumors show many features of normal embryogenesis, such as pluripotency, as governed by the expression of OCT3/4 (see Immunohistochemistry). (medscape.com)
  • [ 8 ] In the vast majority of cases, IGCNU occurs adjacent to invasive germ cell tumors, including embryonal carcinomas. (medscape.com)
  • [ 14 , 15 ] In a series of testicular biopsies of patients with cryptorchidism, the rate of IGCNU was increased, and it is known that, overall, 10% of germ cells tumors are associated with cryptorchidism . (medscape.com)
  • Embryonal carcinomas are aggressive germ cell tumors. (medscape.com)
  • MicroRNAs are small, non-coding RNA molecules that show promise as biomarkers for testicular malignant germ cell tumors. (medscape.com)
  • In all malignant germ cell tumors, microRNAs from two "clusters" (miR-371-373 and miR-302-367) are overexpressed. (medscape.com)
  • A panel of circulating microRNAs from these clusters (miR-371a-3p, miR-372-3p, miR-373-3p, and miR-367-3p) is highly sensitive and specific for diagnosing malignant germ cell tumors, including embryonal carcinoma and seminoma. (medscape.com)
  • Endothelial damage seems to be an essential prerequisite to thrombogenesis in AF. (bham.ac.uk)
  • These toxins appear to directly damage mucosal cells and vascular endothelial cells in the gut wall. (msdmanuals.com)
  • By that the cell surface-to-blood volume ratio reach that of small arteries and veins and suffices to ensure 'natural' anticoagulation in whole blood. (forschung3r.ch)
  • This endothelial surface suffices to ensure 'natural' anticoagulation in whole blood, rendering the use of anticoagulants unnecessary. (forschung3r.ch)
  • However, while many studies demonstrated the importance of the ECM, its interactions with β-cells are still not fully understood. (nature.com)
  • Accordingly, the interaction between blood cells and derived natural factors and interactions with endothelial cells cannot be studied in conventional cell culture systems. (forschung3r.ch)
  • Our results highlight the crucial role of ETP as an obesity-associated factor that promotes tumor growth in the context of adipocyte interactions with tumor and stromal cells. (jci.org)
  • Experiments with endothelial cells fortified with the isolated fraction from native honey enriched in antioxidants, exposed to peroxyl radicals from 1,1-diphenyl-2-picrylhydrazyl (AAPH, 10 mM) and to hydrogen peroxide (H2O2, 50-100 microM), indicated that phenolic acids and flavonoids were the main causes of the protective effect. (researchgate.net)
  • Of translational relevance, several candidate drugs which are endothelial protective have been shown to improve clinical manifestations of COVID-19 patients. (nature.com)
