Neuroprotective effect of bone marrow-derived mesenchymal stem cell secretome in 6-OHDA-induced Parkinson's disease

Aim: The aim of the study was to evaluate the neuroprotective effect of bone marrow stem cell secretome in the 6-hydroxydopamine (6-OHDA) model of Parkinson's disease. Materials & methods: Secretome prepared from mesenchymal stem cells of 3-month-old rats was injected daily for 7 days between days 7 and 14 after 6-OHDA administration. After 14 days, various neurobehavioral parameters were conducted. These behavioral parameters were further correlated with biochemical and molecular findings. Results & conclusion: Impaired neurobehavioral parameters and increased inflammatory, oxidative stress and apoptotic markers in the 6-OHDA group were significantly modulated by secretome-treated rats. In conclusion, mesenchymal stem cell-derived secretome could be further explored for the management of Parkinson's disease.
