This is why cord blood can be used for transplantation as an alternative to bone marrow. Cord blood is being used increasingly on an experimental basis as a source of stem cells, as an alternative to bone marrow. Most cord blood transplants have been performed in patients with blood and immune system diseases.
(= (S + (p. . Solute potential is at a maximum at zero (distilled water), whereas pressure potential can be negative (vacuum), zero (one atmosphere), or positive (greater than zero). So distilled water at normal atmospheric pressure has a water potential of zero ((= 0).
1 Greater concentration of solute inside cell than outside. 2  Water potential is low (0 in distilled water); osmotic potential is higher. 3  Net movement of water into the cell from the solution across a semi-permeable membrane. Net movement of water into the cell from the solution across a semi-permeable membrane. 2  A pure water solution (DH2O) can cause lysis (bursting) in animal cells and turgor pressure in plant cells. 3  Concentration inside cells is equal to that of the solution.
