WebThe anterior brain is first defined as a specific portion of rostral neural ectoderm expressing a set of early neural markers such as hesx1/anf1 and otx2. This initial territory is progressively refined into specific presumptive midbrain and forebrain areas (Wilson and Houart 2004).The anterior–posterior (AP) patterning of the CNS is thought to arise, in … WebLoose of function experiment - stained with otx2 (marker for midbrain and forebrain and Hoxa1 = hind brain and spinal cord marker.

WebMar 9, 2005 · At the gastrula stage when Otx2 expression is crucial for forebrain induction (Rhinn et al., 1999), it is progressively supplanted by the A promoters in the very same areas. Accordingly, it is worth noting that the first published Otx2 knock-out mouse carried a LacZ insertion that removed the common 3′ splice site for A and B transcripts and, therefore, … WebSep 1, 1999 · Otx2 null embryos die early in embryogenesis, lack the rostral neuroectoderm fated to become the forebrain, midbrain and rostral hindbrain, and show major abnormalities in their body plan (Acampora et al., 1995; Matsuo et al., 1995; Ang et al., 1996).
WebOtx2 has been shown to be essential in forebrain devel-opment; the entire forebrain and midbrain fail to develop in Otx2 homozygous mutant embryos (Acampora et al., 1995; Matsuo et al., 1995; Ang et al., 1996).
