After neural tube formation, the neuroepithelium constricts and folds while the tube fills with embryonic cerebrospinal fluid (eCSF) to form the embryonic brain ventricles. We developed this ventricle injection technique to better visualize the fluid filled space in contrast to the neuroepithelial shape in a live embryo.

Supramolecular hydrogelators based on ureido-pyrimidinones allow full control over the macroscopic gel properties and the sol–gel switching behavior using pH. Here, we present a protocol for formulating and injecting such a supramolecular hydrogelator via a catheter delivery system for local delivery directly in relevant areas in the pig heart.

We demonstrate intraperitoneal injection into adult zebrafish. We use a 10 μl NanoFil microsyringe controlled by a Micro4 controller and UltraMicroPump III. This demonstration includes the use of cold water as an anesthetic.
FAQs
The selected site determines where the preparation first contacts tissue or a body compartment, which can shape local exposure and subsequent distribution. A localized placement may emphasize effects near the administration point, whereas access to a body compartment may support broader activity. Comparing sites can therefore help researchers distinguish location-dependent responses from effects caused by the preparation itself.
Dose and volume influence the amount of preparation delivered and how it occupies the selected site. Maintaining calibrated values reduces variation between experimental subjects or models, making biological responses easier to compare. If these parameters change between groups, differences in physiology or therapeutic outcome may reflect delivery conditions rather than the intended activity of the RLT preparation.
The outcome depends on how the preparation moves after delivery and how it interacts with the biological system. Diffusion can extend activity away from the injection site, while cellular uptake or interaction with target molecules can determine which cells respond. These processes help explain why the same preparation may produce a primarily local effect in one setting and a broader response in another.
A consistent workflow establishes the intended tissue, body compartment, or experimental model, selects the injection site, and uses a calibrated needle to deliver a controlled volume. Researchers also define the dose and timing before administration and apply the same conditions across experimental groups. This structured approach limits procedural variation and supports reliable comparison of biological responses.
Researchers may select this approach when they need to administer an experimental reagent and assess its effect in vivo. It can support studies of physiology, disease models, or therapeutic outcomes by linking a defined intervention with measurable biological responses. The method is especially informative when site, dose, timing, and delivery conditions must be controlled to interpret the response.
Interpretation should consider both the biological response and the delivery conditions that produced it. Researchers compare outcomes in relation to dose, injection site, timing, and the preparation’s movement or cellular interactions. Consistent administration strengthens the connection between the intervention and observed physiology, while variation in technique can make it harder to determine whether an outcome reflects biology or delivery.
