After transplanting NIH-3T3-TH engineered cells into the lesioned striatum by stereotaxic technique, the rats were tested for rotationalbehavior induced by apomorphine.
Although the unencapsulated PC12 cells could also improve the rotationalbehavior, the symptom improvement lasted only two months. In addition, several of the grafts developed into mortal tumor.

With the hypothesis of critical gas film thickness, a criterion for expressing the opening behavior of DGS, namely the critical opening rotational speed (CORS), was proposed.
