Fig. 2. Expression pattern of an NSE-Psen1 transgene. (A,B) Horizontal sections
through the lateral telencephalon of an E16.5 NSE-Psen1 transgenic (A) or
non-transgenic littermate control (B) embryos hybridized with a human-specific
PSEN1 probe. In the transgenic embryo there is prominent hybridization in the
intermediate zone (IZ), cortical plate (CP) and marginal zone (MZ), and an
absence of signal in the ventricular zone (VZ). Scale bar: 50 µm.
