Figure 3: 3a): A photomicrograph of a section in the cerebellar cortex of a rat from control group showing delicate dendritic arborizations of Purkinje cells extending up into molecular layer [PTAH x 400].(3b): A photomicrograph of a section in the cerebellar cortex of a rat from group II showing decreased length of Purkinje cell dendrites [PTAH x 400].(3c): A photomicrograph of a section in the cerebellar cortex of a rat treated with CD 34+ stem cells showing increase in the length of dendrites of Purkinje cells [PTAH stainX400]. (3d): A photomicrograph of a section in the cerebellar cortex of a rat treated with CD 34- stem cells showing long dendrites of Purkinje cells extending into the molecular layer [PTAH stainX400].
