Dynamics of primary cilia in endothelial and mesenchymal cells throughout mouse lung development

Developmental Dynamics, Volume 254, Issue 11, Page 1187-1202, November 2025.
Abstract Cilia are specialized structures found on a variety of mammalian cells, with variable roles in the transduction of mechanical and biological signals (by primary cilia, PC), as well as in the generation of fluid flow (by motile cilia). Their critical role in the establishment of a left–right axis in early development is well described, as well ...
