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).
Osmotic pressure is a colligative property, meaning that the property depends on the concentration of the solute but not on its identity. Increasing the pressure increases the chemical potential of the system in proportion to the molar volume (Î´Î¼ = Î´ P V).
