Pancreatic metaplastic cells are precursors of malignant cells that give rise to pancreatic tumors. However, isolating intact viable pancreatic cells is challenging. Here, we present an efficient method for pancreatic tissue dissociation. The cells can then be used for single-cell RNA sequencing (scRNA-seq) or for two- or three-dimensional co-culturing.

Xenopus laevis provides an ideal model system for studying cell fate specification and physiological function of individual retinal cells in primary cell culture. Here we present a technique for dissecting retinal tissues and generating primary cell cultures that are imaged for calcium activity and analyzed by in situ hybridization.
FAQs
Tissue dissection must balance physical separation with preservation of key anatomical features. Careful isolation allows researchers to retain the spatial organization and relationships needed to interpret tissue structure accurately. This matters because damaged or poorly separated regions may be less useful for direct observation, histology, or later cellular and molecular analysis.
Each instrument supports a different level of tissue handling. Scalpels enable controlled cutting, forceps allow researchers to grasp and isolate regions, and microdissection tools support more precise separation of small tissue areas. Selecting and coordinating these instruments helps researchers expose anatomical features while limiting disruption to the structures being examined or sampled.
Dissection reveals how tissues are organized within organs and how their physical relationships may relate to physiological functions. Examining these arrangements can also clarify developmental changes and disease-related alterations. By connecting visible anatomy with histological, cellular, or molecular findings, researchers can study biological mechanisms across multiple levels of organization.
After isolation, a tissue region may be examined directly, prepared for histology, or retained for molecular and cellular assays. Direct examination emphasizes visible organization, whereas histology provides a prepared view of tissue architecture. Molecular and cellular analyses extend the investigation beyond appearance, allowing structural observations to be considered alongside underlying biological features.
The intended question determines the most suitable downstream analysis. Direct observation is appropriate when visible anatomy and relationships are the primary focus. Histology is useful when tissue architecture requires prepared examination, while molecular or cellular assays support investigation of underlying biological mechanisms. A single dissection can therefore support complementary forms of analysis when the sample is handled appropriately.
Biologists apply tissue dissection to investigate organ anatomy, tissue architecture, developmental changes, and disease-related alterations. The approach is especially valuable when researchers need to isolate a particular region before examining it directly or preparing it for additional analysis. These applications make dissection a practical link between anatomical observation and studies of cellular or molecular mechanisms.
