2026
Multiplexed immunofluorescence enables sequential labeling of multiple antibody markers within a single tissue section to support spatial analysis of tissue architecture and cell populations. Here, a workflow for multiplex detection of senescence-associated, structural, and immune markers is presented, including manual and automated slide preparation, iterative imaging, and single-cell analysis using digital pathology software.

The ability to produce transgenes for Caenorhabditis elegans using genomic DNA carried by fosmids is particularly attractive as all of the native regulatory elements are retained. Described is a simple and robust procedure for the production of transgenes via recombineering with the galK selectable marker.

We developed two sets of tracing combinations in Rosa26tdtomato (ubiquitously expressed in all cells)/Cre (specifically expressed in chondrocytes) mice: one with 2.3Col1a1-GFP (specific to osteoblasts) and one with immunofluorescence (specific to bone cells). The data demonstrate the direct transformation of chondrocytes into bone cells.
FAQs
This pattern identifies a tumor-cell subpopulation selected for further study of stem-like behavior rather than proving that every cell has the same functional capacity. Researchers may examine whether the enriched cells show greater self-renewal, tumor initiation, invasion, or treatment resistance. The phenotype therefore serves as an experimental marker for comparing subpopulations, not as a standalone biological conclusion.
Expression patterns are not universal: a phenotype observed in one cancer type or model may not identify the same biological population in another. This variability means researchers should interpret CD44/CD24-defined groups within the specific tumor system being studied. It also limits direct comparisons across experiments unless the cancer type and model context are considered.
Using both markers separates tumor cells into expression-defined subpopulations that a single measurement could merge. Researchers can then compare CD44-high/CD24-low or CD44-positive/CD24-negative cells with other groups when investigating heterogeneity and stem-like traits. This paired analysis supports more precise population-level comparisons, while still requiring functional testing to assess what the phenotype represents.
Flow cytometry or immunostaining is used to assess CD44 and CD24 expression on tumor cells. The resulting expression pattern can distinguish groups such as CD44-high/CD24-low or CD44-positive/CD24-negative from other cells. Researchers can use those measurements to profile heterogeneity or identify populations for subsequent investigation of stem-like properties.
A practical study first measures the two markers, classifies cells according to their combined expression, and then compares the resulting groups. Selected populations may be enriched for closer analysis of self-renewal, tumor initiation, invasion, or treatment resistance. This workflow links a surface-marker phenotype to a research question without treating the marker combination alone as proof of function.
Researchers can compare the relative representation of CD44/CD24-defined subpopulations before and after treatment. A shift in composition may reveal that therapy changes which tumor-cell phenotypes are present, including populations being investigated for treatment resistance. The analysis therefore helps characterize response-associated heterogeneity, although the marker shift itself does not establish why the change occurred.
