Somitogenesis is a rhythmic developmental process that spatially patterns the body axis of vertebrate embryos. Previously, we developed transgenic zebrafish lines that use fluorescent reporters to observe the cyclic genes that drive this process. Here, we culture dispersed cells from these lines and image their oscillations over time in vitro.

This paper describes a striaghforward and efficient method of intubating mice for pulmonary function measurements or pulmonary instillation, that allows the mice to recover and be studied at later times. The procedure involves an inexpensive fiberoptic light source that directly illuminates the trachea.

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures. There are four defined lung volume measures: tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume. Tidal volume is the amount of air inhaled and exhaled in a normal breath. Inspiratory...

Here, we describe the necessary steps for establishing a rat EVLP model and show the inflammatory profile associated with the perfused lungs. The aim is to propagate knowledge and experiences about the rat EVLP model, enabling the integral understanding of the biological responses associated with that revolutionary technique.
FAQs
These signaling systems provide distinct but coordinated molecular inputs during embryonic lung formation. They regulate endodermal specification, epithelial branching, vascular development, and cellular differentiation, allowing neighboring tissues to adopt appropriate developmental states. Their combined activity helps establish both the branching architecture of the respiratory system and the diversity of cells needed for its later function.
Mesoderm-derived signals affect lung development only after they activate receptors on responsive neighboring cells. Receptor activation then changes downstream gene expression, translating an extracellular cue into a developmental response such as specification, branching, vascular formation, or differentiation. This mechanism links communication between embryonic tissues to the construction of organized respiratory structures.
The two embryonic tissues influence one another through reciprocal molecular signaling. Mesoderm supplies signals that guide endodermal fate and epithelial behavior, while the resulting tissue interactions support coordinated development of branches, vessels, and differentiated cell populations. This cross-talk is important because lung architecture and cellular diversity arise from coordinated activity across tissue layers rather than from either layer acting independently.
Lung formation requires several developmental outcomes to occur in an integrated way. Signals must support endodermal specification while also guiding epithelial branching, vascular development, and differentiation. Coordinated signaling connects these processes, helping produce an organized respiratory system with appropriate structural complexity and multiple cell types. Disruption of this coordination can therefore affect both anatomy and cellular composition.
Investigating these pathways identifies developmental processes that are essential for establishing lung structure and cellular diversity. Because fibroblast growth factors, bone morphogenetic proteins, Wnt cues, and retinoic acid regulate specification, branching, vascular development, and differentiation, abnormal signaling could help explain congenital defects affecting those outcomes. The signaling network therefore provides a framework for linking early developmental changes with respiratory abnormalities.
The signaling network provides developmental guidance for efforts to model lung formation outside the embryo. Applying knowledge of mesoderm-derived cues can support attempts to reproduce endodermal specification, epithelial branching, vascular development, and differentiation in organoids. These models may help researchers study respiratory development, investigate disease mechanisms, and explore regenerative therapies that aim to restore damaged lung tissue.
This subject connects embryonic development with experimental models used to investigate respiratory disease. Researchers can examine how altered molecular communication affects lung architecture or cell differentiation, then use developmental models to study disease processes and test treatments. Its relevance extends from understanding congenital conditions to informing organoid-based systems and broader strategies for respiratory repair.
