WHAT IF? Patients with diseases such as heart disease or Alzheimer’scould have their own skin cells reprogrammed to become iPS cells. Once procedures have been developed for converting iPS cells into heart or nervoussystem cells, the patients’ own iPS cells might be used to treat their disease.When organs are transplanted from a donor to a diseased recipient, the recipient’s immune system may reject the transplant, a dangerous condition. Wouldusing iPS cells be expected to carry the same risk? Why or why not? Giventhat these cells are actively dividing, undifferentiated cells, what risks mightthis procedure carry?
What property prevents the ligands of cell-surface receptors from entering the cell? The molecules bind to the extracellular domain. The molecules are hydrophilic and cannot penetrate the hydrophobic inferior of the plasma membrane. The molecules are attached to transport proteins that deliver them through the bloodstream to target cells. The ligands are able to penetrate the membrane and directly influence gene expression upon receptor binding.
