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 andit always has a negative value. 2  The pressure exerted on cell contents by the cellsurface membrane or cell wall is called the pressure potential (Ïp). 3  This isbecause the membrane or wall exerts a force on the cell contents to increasethe concentration of water molecules in the cell. The pressure in the cell3. 2  The temperature â High temp more kinetic energy. 3  4. Solute and Pressure potentialThe concentration of solutes inside the cell is called the solute potential (Ïs). 4  andit always has a negative value.
