Co-localization of GFAP and murine specific thymocyte antigen 1.

<p>Striatal sections of 20 µm thickness of embryonic stem cells, undifferentiated (ES; A–H) and 7 days differentiated cells (7 d; I–P) transplanted group were co-stained for glial fibrillary acidic protein (GFAP; B,F,J,N) and murine specific thymocyte antigen 1 (THY1; C,G,K,O) to examine the origin of these glial cells. Figures A–D and I–L are images from locations within the graft, whereas E–H and M–P are locations along the margin of the graft, showing the host tissue and graft. The dotted lines demarcate the margin. GFAP staining is seen outside the graft margin, whereas THY1 positive cells are seen only inside the graft. Scale bar 50 µm.
