- Which of the following are charcteristics you would expect of a circulating tumor cell that has undergone Epithelial-Mesenchymal Transition (select all that apply)? A. Increased N-cahedrin expression B. Increased resistance to apoptosis C. Loss of ability to secrete fibronectin D. High cytokeratin expression E. Elevated PDGF Receptor ExpressionYou are studying growth factor GFA, which you know stimulates the proliferation of goblet cells in theintestine.Goblet cells are responsible for producing and secreting mucin, a mixture of glycosaminoglycans thatprotects the intestinal wall.Some patients suffering from inflammatory bowel disease (IBD) appear to have fewer goblet cells, thereforeless mucin and less protection from toxins and various other pro-inflammatory factors.These patients also have mutations in the gene encoding the GFA receptor (GFAR) in goblet cells,GFAR is a receptor tyrosine kinase (RTK) that autophosphorylates in response to GFA binding, thusbecoming active.QUESTION:explain what changes in GFAR could be caused by these IBD-associatedmutations and why.Which of the following statements about potency is correct? O A. Committed progenitors have more potency than totipotent stem cells. B. Multipotent stem cells have higher potency than pluripotent stem cells. C. Unipotent stem cells are different from normal somatic cells because they can self-renew. D. Adult tissues have many totipotent stem cells in their niche.
