Objective: Adipose derived stem cells (ASCs) secrete numerous neurotrophic factors and cytokines in conditioned medium (CM), which protect neurons by its antioxidative and trophic effects. This research assesses the neuroprotective effect of ASCCM on neurotrophins genes expressions and tyrosine hydroxylase positive (TH) cell density in male Wistar rats lesioned by 6-hydroxydopamine (6-OHDA).
Materials And Methods: In this experimental study, the groups consisted of lesioned and sham rats with unilateral injections of 20 μg of 6-OHDA neurotoxin and phosphate buffered saline (PBS) into the striatum, respectively.
