A technique to genetically manipulate epithelial cells within whole ex vivo cultured embryonic mouse submandibular glands (SMGs) using viral gene transfer is described. This method takes advantage of the innate ability of SMG epithelium and mesenchyme to spontaneously recombine after separation and infection of epithelial rudiments with adenoviral vectors.

The ventricular cerebrospinal fluid (CSF) bathes the neuroepithelial and cerebral cortical progenitor cells during early brain development in the embryo. Here we describe the method developed to isolate ventricular CSF from rodent embryos of different ages in order to investigate its biological function. In addition, we demonstrate our cerebral cortical explant dissection and culture technique that allows for explant growth with minimal volumes of culture medium or CSF.

We present a protocol to dissect and culture embryonic day 15 (E15) murine metatarsal bones. This highly physiological ex vivo model of endochondral ossification provides conditions closer to the in vivo situation than cells in monolayer or 3D culture and is a vital tool for investigating bone growth and development.
FAQs
Development depends on a two-way signaling relationship between the ureteric bud and the surrounding metanephric mesenchyme. Signals from the bud promote mesenchymal condensation and nephron differentiation, while signals from the mesenchyme stimulate branching morphogenesis in the ureteric bud. This reciprocal exchange coordinates the formation of epithelial and mesenchymal kidney components rather than allowing either tissue to develop independently.
The ureteric bud provides signals that organize nearby mesenchymal cells and support their progression toward nephron differentiation. In the opposite direction, the metanephric mesenchyme sends signals that guide ureteric bud branching. Their distinct but interdependent functions help establish the collecting duct and nephron compartments during early kidney development.
Branching morphogenesis allows the ureteric bud to establish the developing collecting duct system while responding to signals from the surrounding mesenchyme. Because mesenchymal signaling drives this branching behavior, the process provides a clear example of tissue coordination during organ formation. Studying it helps explain how renal structures become patterned through interactions between neighboring embryonic tissues.
Mesenchymal condensation concentrates cells around the developing ureteric bud in response to bud-derived signals. This organized cellular response is linked to nephron differentiation, connecting local tissue arrangement with the emergence of nephron structures. Metanephric rudiments therefore make it possible to examine how signaling between adjacent embryonic tissues influences both cellular organization and specialized renal development.
They provide a developmental model in which researchers can examine reciprocal communication, tissue patterning, and the coordinated emergence of renal structures. The model is especially informative because collecting ducts, nephrons, and supporting renal structures arise through linked interactions between the ureteric bud and metanephric mesenchyme. These features make the system useful for investigating general principles of organ formation.
Studies can focus on how collecting ducts, nephrons, and supporting renal structures become patterned during development. The model connects these outcomes to specific interactions between the ureteric bud and surrounding mesenchyme, allowing researchers to relate signaling behavior to structural organization. This supports analysis of how multiple tissue components are coordinated within a developing organ.
Their development depends on precisely coordinated signaling between two embryonic tissues, so disruptions in these interactions can be examined in relation to abnormal renal formation. The model helps researchers study how problems in mesenchymal condensation, nephron differentiation, or ureteric bud branching may affect kidney patterning. This developmental perspective is relevant to understanding congenital kidney abnormalities.
They reveal signaling relationships that guide the organization of collecting ducts, nephrons, and supporting renal structures. Those developmental principles provide context for tissue-engineering strategies and efforts to generate kidney-like tissues from stem cells. Rather than focusing only on individual cell types, the model emphasizes coordinated interactions needed to reproduce aspects of kidney formation.
