During the early stages of development, expression of EXP7 peaked at stage 71 and the ARF was highly expressed during stages 71-75.
The Arabidopsis genes are highly similar but display different tissue and development expression patterns.
Immunohistochemistry revealed that during early development, expression was associated with proliferating and migrating cells throughout the rodent brain, initially appearing in the proliferative ventricular zones.
During late postnatal development, expression of the NR3B NMDA receptor subunit, a putative dominant-negative subunit that reduces glutamate-induced ionic currents, is upregulated within motor neurons.
During normal human development, expression is restricted to the embryonic period of development [39].
These observations have lead to the conclusion that at early stages of development, expression of cdx-2 is stochastic.
During development, expression of Meltrin β gradually clustered at the NMJ during the late stage of embryogenesis (Figure S1).
To demonstrate that Wnt pathway plays a role in swimbladder development, expression of several genes encoding components of the Wnt pathway was examined.
In addition to its essential role in melanocyte development, expression of Mitf and its target genes is seen in many melanoma cells [21], [22].
During development, expression of DLK mRNA has been primarily detected in neuronal tissues such as brain and spinal ganglion, as well as in the epithelia of the skin, intestine, pancreas, and kidney [22].
In addition to its proposed roles during development, expression of Math6 in adult tissue is suggestive of additional functions of this factor in maintenance of differentiated phenotypes [32][33].
