Functional Characteristics of Multipotent Mesenchymal Stromal Cells from Pituitary Adenomas

Figure 6

Immunohistochemical analysis of proteins associated with neural lineages in pituitary adenoma cell cultures. (a) HA002, NES (green), 100x magnification; (b) HA006, NES (green), 200x magnification; (c) HA006, A2B5 (green), 200x magnification; (d) HA032, ATXN1 (green), 200x magnification. Nuclei were stained with DAPI (blue). All analysed samples showed great NES expression, mild A2B5 and GFAP staining, and, in several cells, very weak ATXN1 expression. NES, nestin; A2B5 binds to neural tissue such as brain, spinal cord, and dorsal root ganglia; GFAP, glial fibrillary acidic protein; ATXN1, ataxin 1.
