To investigate whether Dkk1 deficiency may have the opposite effect on the specification between SE and NE, we analyzed Dkk1 null mutant embryos with specific markers (Fig. 4L X, Fig. S2D′′ F′′) (Pietila et al., 2011).
Together, these findings suggested that Wnt signaling is one of the candidate pathways controlling the specification between NE or SE fate in uncommitted progenitors during neural tube closure.
Initially, we surveyed the Wnt, FGF, and BMP ligands, which are thought to be involved in the specification between neural and epidermis fates prior to or during gastrulation in other vertebrates (Murry and Keller, 2008).
To explore the possibility that Dkk1 can affect the specification between NE- and SE cell fates, we examined molecular markers in CAG-Dkk1 embryos with high-resolution immunohistochemistry (Fig. 4D K′).
In accord with the hypothesis that the specification between NE and SE fates is altered, the NE markers Sox2 and N-cadherin were down-regulated (Fig. S2K, L), whereas the SE markers Tfap2c, E-cadherin, and TROMAI were enhanced by Wnt8A misexpression (Fig. S2H′, I′, M P).
Why is there this specifications between civilian defense and non-civilian defense?" These are the questions one must think about and think of any other questions that may arise.
Until this is described by the specification, differences between implementations of Universal SMILES will occur to the lack of a common aromatic model.
It is necessary to compare the same specification between the near-infrared and visible light interferometers.
While the specification of service quality standards is a common practice, the relationships between the specifications and customer satisfaction are often methodologically unclear.
The difference between the specifications of each model lies in the explanatory variables (open innovation practice: customer involvement, external networking, outsourcing R&D, inward IP licensing).
