- Protein Wnt 3a Precursor
- Protein Wnt-3a
- Wingless type MMTV integration site family member 3A
FunctionLigand for members of the frizzled family of seven transmembrane receptors. Wnt-3 and Wnt-3a play distinct roles in cell-cell signaling during morphogenesis of the developing neural tube.
Tissue specificityModerately expressed in placenta and at low levels in adult lung, spleen, and prostate.
Sequence similaritiesBelongs to the Wnt family.
Cellular localizationSecreted > extracellular space > extracellular matrix.
- Information by UniProt
Human embryonic stem cells (HUES4) were differentiated as monolayer cultures on matrigel coated dishes using a protocol described in Kroon et al, Nat Biotechnol. (2008). Inhibin beta A (ab50051) and Wnt3a (ab81484) were added to cultures to direct differentiation towards definitive endoderm. This image was taken 3 days after induction, where the definitive endoderm marker FOXA2 (ab40874 in green) is abundant. Dapi staining is shown in blue. Magnification: 200x. Negative controls of fluorescently conjugated secondary antibodies only showed no staining.
