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 that indicates how much solute is dissolved in water. It can be calculated using the vanât Hoff equation, shown in equation 2. Note that this form of. the vanât Hoff equation is used to determine the osmotic pressure of ideal solutions.
