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).
The standard electrode potentials are customarily determined at solute concentrations of 1 Molar, gas pressures of 1 atmosphere, and a standard temperature which is usually 25Â°C. The standard cell potential is denoted by a degree sign as a superscript. Measured against standard hydroden electrode.
