Effects of Alternative Splicing-Specific Knockdown of Tjp1 α+ by Rbm47 on Tight Junctions Assembly during Blastocyst Development
This study shows that selective knockdown of Tjp1 + via Rbm47 siRNA in mouse blastocysts does not impair blastocyst development or TJ permeability, indicating Tjp1 + is not essential for TJ assembly during early development.
