In this video-article we present a method for isolating single or multiple Drosophila da neurons from third instar larvae using the infrared capture (IR) class of Laser Capture Microdissection (LCM). RNA obtained from the isolated neurons can be readily used for downstream applications including qRT-PCR or microarray analyses.

Source: Kay Stewart, RVT, RLATG, CMAR; Valerie A. Schroeder, RVT, RLATG. University of Notre Dame, IN The Guide for the Care and Use of Laboratory Animals1 dictates that rodent survival surgery be performed aseptically. Aseptic technique utilizes specific practices that minimize the contamination of the surgical site, including patient preparation, surgeon preparation, sterilization of instruments and other supplies, and the use of a clean and controlled environment. Presurgical planning,...

Stereotaxic (or stereotactic) surgery is a method used to manipulate the brain of living animals. This technique allows researchers to accurately target deep structures within the brain through the use of a stereotaxic atlas, which provides the 3D coordinates of each area with respect to anatomical landmarks on the skull. After the skull is exposed, anesthetized animals are mounted on a specialized instrument known as a stereotaxic frame, which enables the precise placement of experimental...

FAQs
Magnification provides the visual detail needed to distinguish adjacent tissue structures at a microscopic scale. Fine microsurgical instruments then permit the operator to separate, remove, or manipulate only the intended structure, while controlled movements help maintain relevant tissue planes. This combination supports precise targeting and reduces unintended disruption of nearby vessels, nerves, or cellular components during biological investigations.
Tissue planes act as boundaries that help guide separation between structures. Identifying them allows the operator to isolate a target without unnecessarily disrupting neighboring material. In practice, careful plane recognition supports preservation of surrounding anatomy, which matters when the procedure is used for tissue sampling, transplantation, or studies examining how distinct structures contribute to biological function.
Preserving nearby vessels, nerves, and cellular components helps maintain the biological context of the target region. That context is important when researchers collect tissue, perform transplantation procedures, or compare structure with function. Limiting disruption also helps experimental observations reflect the role of the selected tissue rather than effects caused by damage to neighboring components.
A microdissection surgery workflow begins by viewing the region under magnification, identifying the target and its surrounding tissue planes, and selecting an appropriate fine instrument for the intended manipulation. The operator then uses controlled movements to separate, remove, or handle the target while protecting adjacent structures. These requirements make precision central at every stage.
Microdissection surgery can support tissue sampling, anatomical studies, transplantation procedures, and investigations of structure-function relationships. Its value differs by application: sampling focuses on obtaining selected tissue, anatomical work examines organization, transplantation requires careful manipulation, and structure-function studies connect a specific region with its biological role.
By enabling targeted intervention in a specific tissue, the technique lets investigators examine how that tissue contributes to development, disease, or repair. This precision can improve the accuracy of experimental procedures and help relate localized structural changes to broader biological processes, especially when surrounding tissues must remain comparatively undisturbed.
