Updates in the pathophysiological mechanisms of Parkinson’s disease: Emerging role of bone marrow mesenchymal stem cells

Figure 3 Photomicrograph of brain section of: A: Ovariectomized control group shows congestion in blood vessels of striatum (v) (H and E × 80); B: untreated Parkinson’s disease (PD) group shows congestion in blood vessels and capillaries of striatum (v) (H and E × 80); C: Untreated PD: Parkinson’s disease group shows hyalinization with plaques formation in the matrix of striatum (H and E × 160); and D: PD group treated with bone marrow derived mesenchymal stem cells shows intact histological structure of the striatum (H and E × 80).
