Cell sheet technology (CST) has primarily been applied in tissue engineering for repair purposes. Our preliminary research indicates that an in vivo prostate cancer model established using CST outperforms traditional cell suspension methods. However, the potential for CST to be used with bladder cancer cells has not yet been explored. In this study, we investigated the ability of two bladder cancer cell lines, T24 and 5637, to form cell sheets. We found that T24 cells successfully formed cell sheets. We then performed staining to evaluate the integrity, specific markers, and proliferation characteristics of the T24 cell sheets. Our findings demonstrate that bladder cancer cell sheets can be established, providing a valuable tool for both in vivo and in vitro bladder cancer studies and for personalized drug selection for patients.

Aberrant activation of fibroblast growth factor receptors (FGFRs) plays a critical role in tumorigenesis across multiple cancer types, driving the development of various FGFR inhibitors. Despite clinical advances, therapeutic efficacy remains limited by the emergence of drug resistance, primarily mediated by gatekeeper mutations in FGFRs. To overcome this challenge, we designed and synthesized a novel series of 7-(1-methyl-1-indole-3-yl)-5-pyrrolo[2,3-]pyrazine derivatives as covalent pan-FGFR inhibitors targeting both wild-type and gatekeeper mutants.

B cells located in tertiary lymphoid structures (TLSs) may undergo clonal expansion, somatic hypermutation, isotype switching, and tumor-specific antibody production, suggesting that antibody-producing plasma cells may be involved in antitumor immunity. This study used a combination of single-cell sequencing (five samples from our center, and four samples from PRJNA662018) and spatial transcriptome (one sample from our center, and four samples from GSE169379) research methods to investigate the relationship between TLSs and the immunoglobulin repertoire in muscle invasive bladder cancer (MIBC). 405 patients with MIBC from TCGA and 348 patients with metastatic urothelial carcinoma on PD-L1 inhibitor treatment from the IMvigor210 trial were included in this study.

Muscle-invasive bladder cancer (MIBC) with cardiac metastasis typically carries a very poor prognosis. A Black woman in her 70s developed high-grade urothelial carcinoma with squamous differentiation invading the bladder muscle. Despite chemotherapy, radiation, and nephrostomy, the disease progressed.

In metastatic colorectal cancer (mCRC) patients with proficient mismatch repair (pMMR)/microsatellite stability (MSS), beyond third-line therapies were extremely limited. Here, we reported a case of a 21-year-old male patient with pMMR/MSS mCRC who failed to respond to both first- and second-line treatment and subsequently received non-standard third-line therapy at a local hospital. This patient was referred to our hospital, and we initiated salvage therapies.
