Protein Wnt-8a is a protein that in humans is encoded by the WNT8A gene. Wnt8a may be involved in the development of early embryos as well as germ cell tumors. The Wnt8a gene is part of the Wnt family of genes and plays a role in vertebrates in the process of axis patterning. Wnt8a encodes for 2 proteins, Wnt8a.1 and Wnt8a.2 via a complicated mechanism involving the coordination of signaling molecules to control up and down stream promoters. Furthermore, Wnt8a has shown to play a role in neural crest induction via Wnt/β-catenin signaling based on experiments using zebrafish as a model organism. Wnt8a among other Wnt genes influence the Wnt/β-catenin signaling in neural crest development. β-catenin is degraded in the absence of a Wnt signaling, but upon the binding of a Wnt ligand with a frizzled receptor and Lrp5/6 the β-catenin signaling molecule is no longer degraded. Instead, it interacts with transcription factors that activate Wnt expression, of which, Wnt8 is crucial for neural crest development and other cell fates. In a study of morpholino based gene knockdown in zebrafish, knocking down Wnt8a resulted in the lack of expression of various other genes important for neural crest induction (pax3, sox10, and foxd3). It is unclear however, if the loss of these neural crest specifiers is a result of Wnt8a directly in the induction process or is a downstream consequence of disruptions in Wnt8a signaling earlier in development. Regardless, the results of this study show Wnt8a as a key player in neural crest induction.

Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (HA721341) at 1/1,000 dilution was used in 5% NFDM/TBST at room temperature for 2 hours. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1:200,000 dilution was used for 1 hour at room temperature.
Immunocytochemistry analysis of NIH/3T3 cells labeling WNT8A with Rabbit anti-WNT8A antibody (HA721341) at 1/50 dilution.
Cells were fixed in 4% paraformaldehyde for 10 minutes at 37 ℃, permeabilized with 0.05% Triton X-100 in PBS for 20 minutes, and then blocked with 2% negative goat serum for 30 minutes at room temperature. Cells were then incubated with Rabbit anti-WNT8A antibody (HA721341) at 1/50 dilution in 2% negative goat serum overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (iFluor™ 488, HA1121) was used as the secondary antibody at 1/1,000 dilution. Nuclear DNA was labelled in blue with DAPI.
Beta tubulin (M1305-2, red) was stained at 1/100 dilution overnight at +4℃. Goat Anti-Mouse IgG H&L (iFluor™ 594, HA1126) was used as the secondary antibody at 1/1,000 dilution.

Cells were fixed and permeabilized. Then stained with the primary antibody (HA721341, 1ug/ml) (red) compared with Rabbit IgG Isotype Control (green). After incubation of the primary antibody at +4℃ for an hour, the cells were stained with a iFluor™ 488 conjugate-Goat anti-Rabbit IgG Secondary antibody (HA1121) at 1/1,000 dilution for 30 minutes at +4℃. Unlabelled sample was used as a control (cells without incubation with primary antibody; black).
