MC38 tumor-bearing mice were divided into three experimental groups: untreated control, FOLFOX-treated, and FOLFOX plus composite probiotics-treated. Tumors were harvested at a defined endpoint, dissociated into single-cell suspensions, and subjected to scRNA-seq using the 10x Genomics platform. The resulting data enable high-resolution characterization of transcriptional changes across immune, stromal, and malignant cell populations within the TME. This dataset aims to elucidate how combinatorial probiotic and chemotherapy intervention reshapes cellular composition, cell-state transitions, and intercellular communication networks, potentially revealing mechanisms of enhanced anti-tumor immunity or therapy resistance.2026/06/01GSE316313GSM9449362GSM9449361GSM9449360GSM9449359GSM9449358GSM9449357GSM9449356GSM9449355GSM944935424247316313Mus musculus
