Source: Rufián, J. S., et al, Single-Cell Analysis of the Expression of Pseudomonas syringae Genes within the Plant Tissue. J. Vis. Exp. (2022)This video demonstrates a syringe-based pressure method for extracting apoplastic bacteria, which proliferate and form microcolonies within the apoplast, the intercellular space between plant cells. The method yields debris-free bacterial samples suitable for downstream single-cell analysis.

Human tumor xenografts in immunodeficient mice are valuable tools to study cancer biology. Specific protocols to generate subcutaneous and intrahepatic xenografts from human hepatocellular carcinoma cells or tumor fragments are described. Liver regeneration induced by partial hepatectomy in recipient mice is presented as a strategy to facilitate intrahepatic engraftment.

This video demonstrates the induction of systemic inflammation in an anesthetized mouse. The injection of mycobacterial antigen-adjuvant depots triggers cytokine release and localized inflammation. Lymphatic vessels open, enabling immune cell entry into lymph nodes and activation of T cells, which release pro-inflammatory cytokines, leading to widespread inflammation.

We standardized an abdominal adipose tissue biopsy using a non-diathermy method performed under local anesthesia. Three cases of excessive post-operation bleeding out of 115 operations (2.61%) occurred.We conclude that an abdominal adipose tissue surgical biopsy using a non-diathermy method can be safely applied to healthy men.
FAQs
Injection angle should be selected together with needle length and the patient’s tissue depth. A short needle may require a different approach from a longer one because the goal is to place the medication within subcutaneous tissue rather than at an unintended depth. Matching these factors supports consistent delivery and helps avoid local tissue irritation.
Fatty tissue supports gradual absorption into the circulation, which is relevant for therapies delivered subcutaneously. This route is therefore used for medications such as insulin and anticoagulants. Because subcutaneous syringes are intended for small volumes, the selected device should correspond to the prescribed dose to support accurate administration.
Repeated injections at one location can contribute to local tissue irritation, making site rotation an important part of ongoing care. Rotating sites distributes the burden of injections rather than repeatedly stressing the same area. This practice is especially relevant when patients administer medication regularly, including during self-injection outside a healthcare setting.
When choosing a subcutaneous syringe, clinicians must consider sterility, needle design, tissue depth, and medication volume. The device uses a short, fine needle and is intended for small volumes, while needle length and patient anatomy influence the selected injection angle. These choices affect placement, dose delivery, and the risk of local tissue irritation.
An administration workflow begins with selecting a sterile syringe suited to the small medication volume, then considering the patient’s tissue depth and the needle length. The needle is inserted at the angle appropriate to those factors, and the plunger is pressed to deliver the medication into subcutaneous tissue. Correct selection and technique support accurate dosing.
This route supports routine clinical therapies including insulin and anticoagulants, and it can be useful when patients need to inject themselves outside healthcare settings. Reliable self-injection depends on using the appropriate syringe, applying the intended angle, and rotating sites. Together, these measures help maintain dosing accuracy while reducing local tissue irritation.
