This protocol describes the rapid non-enzymatic dissociation of fresh human tissue fragments for qualitative and quantitative assessment of CD45+ cells (lymphocytes/leukocytes) present in various normal and malignant human tissues. Additionally, the supernatant obtained from the primary tissue homogenate can be collected and stored for further analysis or experimentation.

Cancer Associated Fibroblasts (CAFs) facilitate tumor initiation, growth and progression through signaling that promotes proliferation, angiogenesis, and inflammation. Here we describe a method to isolate pure populations of normal fibroblasts and CAFs from fresh mouse and human tissues by cell sorting, using PDGFRα as a surface marker.

Tumor organoids have revolutionized cancer research and the approach to personalized medicine. They represent a clinically relevant tumor model that allows researchers to stay one step ahead of the tumor in the clinic. This protocol establishes tumor organoids from fresh pancreatic tumor tissue samples and patient-derived xenografts of pancreatic adenocarcinoma origin.
FAQs
Timing matters because fixation or extensive processing can alter features that may be important to the clinical question. Examining tissue while its native cellular and biochemical characteristics remain available gives investigators more information than a permanently prepared specimen may provide. This flexibility supports selection of gross assessment, rapid sectioning, microscopy, or molecular testing according to the information needed.
The key interpretive advantage is the ability to relate tissue structure to molecular findings within the same diagnostic or investigative context. Microscopic observations can therefore be considered alongside molecular test results rather than in isolation. In medicine, this integrated view can support biomarker analysis and improve understanding of how cellular features relate to disease processes.
Conventional preparation fixes or extensively processes tissue before examination, whereas fresh-tissue workflows keep more native characteristics available at the point of assessment. This distinction matters when processing-related changes could affect interpretation. Fresh tissue analysis therefore complements, rather than universally replaces, conventional preparation, with the clinical question determining which examination approach is most appropriate.
After newly collected tissue becomes available, the workflow can begin with gross assessment and proceed, as appropriate, to rapid sectioning, microscopy, or molecular testing. These options do not represent one mandatory sequence; they are selected according to the clinical question. The workflow can thus preserve access to structural and biochemical information needed for assessment.
It is especially relevant when clinicians need timely diagnostic assessment, biomarker analysis, or information that may support surgical decision-making. The approach also fits investigations of cancer, infection, inflammation, and other pathological conditions. Its value lies in matching the available tissue examination to the immediate clinical question while keeping cellular and biochemical characteristics available for additional evaluation.
In research, fresh tissue analysis helps investigators study disease mechanisms by combining observations of tissue structure with molecular findings. This is relevant to cancer, infection, inflammation, and other pathological conditions, where both cellular appearance and biochemical information may matter. The resulting material can support biomarker investigation and connect tissue features more closely with disease-related questions.
