  • An antibody is a protein molecule that consists of about four polypeptide chains and various chains, some of which have specific regions that are designed to attach to antigenic substances. (differencebetween.net)
  • In the multicellular theory, each tumor type is associated with a specific differentiated cell of origin within the salivary gland unit. (medscape.com)
  • We still do not know what specific factors contribute to the success in transplantation i.e. what cells are responsible for motor recovery? (lu.se)
  • A decrease in hemoglobin can lead to a shortage of oxygen in cells and tissues throughout the body. (medlineplus.gov)
  • A germ layer is a group of cells in an embryo that interact with each other as the embryo develops and contribute to the formation of all organs and tissues. (asu.edu)
  • By contrast, the Gini coefficients for ABC transporters tend to be larger in cell lines than in tissues, implying that some kind of a selection process has taken place. (biorxiv.org)
  • The lowest four in tissues are FAM32A, ABCB7, MRPL21 and PCBP1, while the lowest three in cell lines are SF3B2, NXF1 and RBM45. (biorxiv.org)
  • PCBP1 is both reasonably highly expressed and has a low Gini coefficient in both tissues and cell lines, and is an excellent novel housekeeping gene. (biorxiv.org)
  • The results show that lysophosphatidic acid signalling pathways influence retraction of processes in oligodendrocyte precursors but that this effect changes as oligodendrocytes differentiate. (nih.gov)
