The present invention is concerned with novel processes for the preparation of -1-phenyl)ethan-1-ol. According to the method, fibrocytes from a living donor, preferably the patient, and rotator cuff tissue is harvested from a recently deceased human or animal donor in a manner which retains the extracellular matrix. A separating ring has a vacuum-tight engagement with confronting surfaces of the first electrode and the second electrode to define an evacuatable processing region therebetween.
