  • Human colon cancer cell lines (CRCs) RKO, SW480 and SW620 were investigated for TG2 involvement in tumour advancement and aggression. (oncotarget.com)
  • In the human reproductive process, two kinds of sex cells ( gametes), are involved: the male gamete (sperm), and the female gamete (egg or ovum). (wikibooks.org)
  • On these surfaces, the cells perform secretion and filtration. (wikipedia.org)
  • These cells offer some protection and function in filtration and secretion. (wikipedia.org)
  • As many as 30-40% of patients who have a thymoma experience symptoms suggestive of MG. An additional 5% of patients who have a thymoma have other systemic syndromes, including red cell aplasia, dermatomyositis, systemic lupus erythematosus (SLE), Cushing syndrome, and syndrome of inappropriate antidiuretic hormone secretion (SIADH).

  • Different pathologists have their own interpretations and opinions of the histopathological definitions of dysplastic epithelial lesions. (techscience.com)
  • Typical neuropathological lesions including tangles composed of hyperphosphorylated tau protein as well as severe neuronal cell death characterize these disorders. (karger.com)
  • It is a highly conserved network that orchestrates cell-fate decisions in the nervous, gastrointestinal, and the hematopoietic systems of many organisms ranging from insects to humans. (molvis.org)
  • Cells of hematopoietic origin are individual cells, mostly round in shape, and have a distinct cytoplasmic membrane. (vin.com)
  • The cellularity is usually slightly less than in preparations with hematopoietic cells. (vin.com)
  • Polarized epithelial barriers establish two types of interactions. (hindawi.com)
  • Simple cuboidal cells are also found in renal tubules of nephrons, glandular ducts, and thyroid follicles. (wikipedia.org)
  • Based on this suggested technique, we developed a bioprinted 3D esophageal structure with multi-layered features and converged with biochemical microenvironmental cues of esophageal tissue by using decellularizedbioinks from mucosal and muscular layers of native esophageal tissues. (nature.com)
  • They deliver these microparticles, via TRANSCYTOSIS, to lymphoid tissue for efficient mucosal as well as systemic immune responses. (bvsalud.org)
  • Compared to the endothelium, the molecular mechanisms involved in the interaction of infiltrated or tissue-resident immune cells with parenchymal barriers have not been so extensively studied. (hindawi.com)
  • Tissue homeostasis is critically dependent on the function of tissue-resident lymphocytes, including lipid-reactive invariant natural killer T (iNKT) cells. (elifesciences.org)
  • Chronic exposure of rats resulted in increased thyroid follicular cell tumors from sustained perturbation of thyroid hormone homeostasis. (cdc.gov)
  • Beyond the common features shared by all iNKT cells (including their CD1-restriction and innate-like properties), cells found in discrete tissues have distinct phenotypes and functions that critically modulate the outcome of immunity ( Crosby and Kronenberg, 2018 ). (elifesciences.org)
  • However, detecting and grading dysplasia are routine in histopathological diagnosis as they determine the first signs of tissue changes. (techscience.com)
  • The Integrative Cell and Tissue Dynamics Group is looking for Postdoctoral Researcher to work on engineering organoid systems. (ibecbarcelona.eu)
  • One way that leading and trailing edge dynamics could possibly be coordinated between migrating epithelial cells is certainly by using a planar signaling program. (brain-tumor-cancer-information.com)
