Photomicrographs that demonstrate sites of implantation of bone MSCs in the striatum of adult rats. (a) Site of implantation of human MSCs after 14 days. Arrows indicate needle track. Hemotoxylin and eosin stain. (b) Adjacent section to a stained with antibodies to HLA-ABC. (c) Adjacent section to a examined for nuclear fluorescence of human MSCs. Arrows indicate needle track. (d) Site of implantation of human MSCs after 72 days. Section examined for nuclear fluorescence. (e) Same as d 30 days after implantation. (f) Site of implantation of rat MSCs 14 days after implantation. Examined for nuclear fluorescence. (Magnification: a and b, ×10; c–f, ×4.)
