WNT8A and gastric cancer: Interestingly, we could not detect the actin motor myosin 10 (MYO10), which regulates the formation and elongation of filopodia (Berg and Cheney, 2002) on WNT7A-positive dendritic filopodia (Fig. 1I), suggesting a difference from the Wnt8a cytonemes observed in zebrafish gastrulation (Stanganello et al., 2015) or WNT3 cytonemes in human gastric cancer (Routledge et al., 2022).
