Figure 2: (2a): A photomicrograph of a section in the cerebellar cortex of a rat from control group showing purple Nissl granules (arrow) in the perikarya of Purkinje cells [Cresyl fast violet x 1000]. (2b): A photomicrograph of a section in the cerebellar cortex of a rat from group 2 showing decreased purple Nissl granules (arrow) in the perikarya of Purkinje cells [ Cresyl fast violet x 1000]. (2c): A photomicrograph of a section in the cerebellar cortex of a rat treated with CD 34+ stem cells showing increase in purple Nissl granules in the perikarya of Purkinje cells, compared to that of MSG group [Cresyl fast violet x 1000].(2d): A photomicrograph of a section in the cerebellar cortex of a rat treated with CD 34-stem cells showing increase in purple Nissl granules ( arrow) in the perikarya of Purkinje cells,compared to that of MSG group [Cresyl fast violet x 1000].
