Annotation description:Figure 5: "Endogenous WRP (SRGAP3) protein is expressed throughout the developmental time period of synaptogenesis (supplemental Fig. S3G). Thus the role of WRP during spinogenesis was tested in vitro (Fig. 5) by transfecting cultured neurons from WRPflox/flox mice with GFP-Cre and the soluble fill tdTomato at different time points and then performing image analysis to assess the effect on spine formation and development.

Transfection of Cre at DIV5 (before dendritic filopodial formation) resulted in a 20% reduction in spine density (Fig. 5E-G). In contrast, transfection of Cre at DIV9 (after dendritic filopodia appear) had no significant effect on spine density (Fig. 5H-J). Together, these results strongly support the hypothesis that WRP is required during the early (filopodial) stages of spine development."
