Aerocyte specification and lung adaptation to breathing is dependent on alterna...
Fidalgo, Marta F.; Fonseca, Catarina G.; Caldas, Paulo; Raposo, Alexandre A. S. F.; Balboni, Tania; Henao-Mišíková, Lenka; Grosso, Ana R.Adaptation to breathing is a critical step in lung function and it is crucial for organismal survival. Alveoli are the lung gas exchange units and their development, from late embryonic to early postnatal stages, requires feedbacks between multiple cell types. However, how the crosstalk between the alveolar cell types is modulated to anticipate lung adaptation to breathing is still unclear. Here, we uncovered a...
Competition for endothelial cell polarity drives vascular morphogenesis in the ...
Barbacena, Pedro; Dominguez-Cejudo, Maria; Fonseca, Catarina G.; Gómez-González, Manuel; Faure, Laura M.; Zarkada, Georgia; Pena, AndreiaBlood-vessel formation generates unique vascular patterns in each individual. The principles governing the apparent stochasticity of this process remain to be elucidated. Using mathematical methods, we find that the transition between two fundamental vascular morphogenetic programs—sprouting angiogenesis and vascular remodeling—is established by a shift of collective front-to-rear polarity of endothelial cells ...
