Recently studies have focused on stem cells therapy, therefore the goal of this study was to investigate the effect of adipose derived stem cells grafting, on locomotion and imbalance in Parkinson model of rats. Twenty-four male Wistar rats weighing 200-250 g were divided into three groups including: sham, MPTP, MPTP-stem-cell. Rats were cannulated by stereotaxic apparatus in medial forebrain bundle (MFB) under anesthesia. Then MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) (1&micro;m/2&micro;l) were injected bilaterally into the MFB to induce Parkinson model. Rotation (following apomorphine injection) and Ladder Rung Walking Task were conducted to confirm model of Parkinson, then stem cells from passage 3 (5 &times;103 cells/mm3) were infused into the MFB. After 6 weeks Ladder test was repeated. The results showed that administration of MPTP significantly caused motor disability (p=0.025) and treatment of stem-cells significantly improved motor activity and imbalance (p=0.05). Our findings indicate that grafting of stem cells derived from adipose tissue improves behavioural dysfunctions probably by regeneration of dopaminergic neurons.</p> Parkinson Disease/ MPTP/ Ladder Test/ Stem Cell Grafting 78 78 http://shefayekhatam.ir/browse.php?a_code=A-10-24-1196&slc_lang=en&sid=1 Somayeh Kouhestani Somayeh Kouhestani kouhestani1370@yahoo.com 100319475328460016157 100319475328460016157 Yes Cellular and Molecular Research Center, Faculty of Medicine, Guilan University of Medical Sciences, Rasht, Iran Cellular and Molecular Research Center, Faculty of Medicine, Guilan University of Medical Sciences, Rasht, Iran Parvin Babaei Parvin Babaei 100319475328460016158 100319475328460016158 No Cellular and Molecular Research Center, Faculty of Medicine, Guilan University of Medical Sciences, Rasht, Iran Cellular and Molecular Research Center, Faculty of Medicine, Guilan University of Medical Sciences, Rasht, Iran Bahram Soltani Tehrani Bahram Soltani Tehrani 100319475328460016159 100319475328460016159 No Cellular and Molecular Research Center, Faculty of Medicine, Guilan University of Medical Sciences, Rasht, Iran Cellular and Molecular Research Center, Faculty of Medicine, Guilan University of Medical Sciences, Rasht, Iran Arsalan Alizadeh Arsalan Alizadeh 100319475328460016160 100319475328460016160 No Cellular and Molecular Research Center, Faculty of Medicine, Guilan University of Medical Sciences, Rasht, Iran Cellular and Molecular Research Center, Faculty of Medicine, Guilan University of Medical Sciences, Rasht, Iran
