Figure 5. Assessment of drug-induced rotation. A).

Amphetamine-induced net ipsilateral rotations before (PRE) and 2 months after transplantation (POST). Note the trend for a partial recovery observed in the majority of animal groups. Since the present work required examination of many clones, the number of animals per group was kept to a minimum (3–5) and thus non-significant trends are observed. B) Clone 30 transplants were twice as effective than the polyclonal hVM1-Bcl-X_L cel grafts in inducing rotation compensation.
