Single-cell RNA Sequencing Reveals Cellular Heterogeneity in Tumor Microenvironments

Jacob Fan

Single-cell RNA sequencing (scRNA-seq) has emerged as a powerful tool to unravel the cellular diversity within tumor microenvironments. This study explores the application of scRNA-seq to characterize the heterogeneity of cancer and stromal cells in various tumor types. By profiling individual cells, we identified distinct cellular subpopulations, revealed their unique gene expression signatures, and uncovered dynamic interactions within the tumor microenvironment. Our findings provide insights into the complexity of tumor biology, highlighting potential therapeutic targets and biomarkers for personalized cancer treatment.

Molecular Mechanisms of Exosome Biogenesis and their Roles in Intercellular Communication

Xiaofang Wei

Exosomes are small extracellular vesicles (30-150 nm) that play a crucial role in intercellular communication by transporting proteins, lipids, and RNA between cells. This review explores the molecular mechanisms underlying exosome biogenesis, focusing on the Endosomal Sorting Complex Required for Transport (ESCRT)-dependent and ESCRT-independent pathways. Additionally, we examine the roles exosomes play in physiological and pathological processes, including immune response, tumour progression, and neurodegenerative diseases. Understanding the biogenesis and function of exosomes could lead to novel therapeutic strategies for various diseases.
