Effect of engraftment on rotation. (A): Engraftment with human adult olfactory neural progenitors (transfected and nontransfected) reduced rotation compared with medium or fibroblasts (p < .01). (B): Effect of time on rotation. No differences were found between fibroblast and medium groups. (C,
D): Corner and cylinder analyses were equivalent to the rotation. (B–D): Error bars indicate SD. Abbreviations: d, days; IPN, pIRES-Pitx3-Nurr1; NS, not significant; w, weeks.
