Expression of p75 in oligodendrocytes infected with the trkA retrovirus. Differentiated oligodendrocytes infected with trkA retrovirus were stained for alkaline phosphatase (a) and p75 receptors (b) using the 9651 anti-p75 polyclonal antibody (Huber and Chao, 1995a). Cultures were allowed to grow in oligodendrocyte differentiation media for 7 d before staining. Cell shown was TUNEL-negative. Magnification, 400×.
