Characterization of the grafted cells in the striatum.

<p>Striatal sections of the rotenone-infused control (ROT), embryonic stem cells transplanted animal (ES) and 7 days differentiated cells transplanted animal (7 d) were processed for presence of dopaminergic cells positive for tyrosine hydroxylase (TH) immunoreactivity. Sections were stained with cresyl violet (A, E and I) for localization of neurons (Scale bars for both inset as well as the main frame are 100 µm), and with DAPI for nuclei (B,F,J). Sham transplanted (ROT; B–D); undifferentiated embryonic stem cells transplanted (ES; F–H) and 7 days differentiated cells grafted (7 d; J–L) striatal images are shown. Scale bar is 50 µm for these figures. Scale bar for the magnified images showing TH positive cells, in the right hand corners of the lower panel is 10 µm.
