Scientific Context: Exosomes as Drivers of Pancreatic Tumor Biology

Pancreatic cancer, especially pancreatic ductal adenocarcinoma (PDAC), is characterized by aggressive progression, early metastasis, and poor prognosis. One emerging hallmark of PDAC is the active role of extracellular vesicles, especially exosomes, in intercellular communication. These nanoscale vesicles carry a diverse cargo of proteins, lipids, mRNAs, and non-coding RNAs that reprogram recipient cells in the tumor microenvironment (TME) and distant organs.

Pancreatic tumor-derived exosomes have been found to:

Stimulate pancreatic stellate cell activation and fibrotic stroma formation
Promote epithelial-mesenchymal transition (EMT)
Enable immune evasion and immune cell reprogramming
Establish pre-metastatic niches in organs like the liver and lungs
Mediate resistance to chemotherapeutic agents

Understanding how tissue-derived exosomes regulate these pathways can unlock new targets for early detection and treatment of pancreatic cancer. At Creative Biolabs, we are committed to empowering academic and translational researchers with cutting-edge tools and services for studying pancreatic cancer tissue-derived exosomes. Leveraging years of scientific experience in exosome biology, molecular profiling, and tumor microenvironment modeling, our platform offers customized support for projects exploring the biological and pathological functions of exosomes in pancreatic ductal adenocarcinoma (PDAC).

Biological Focus Areas of Pancreatic Cancer Exosomes

Exosome-Stellate Cell Interactions

A key hallmark of pancreatic cancer is the desmoplastic response—driven by pancreatic stellate cells (PSCs). Exosomes from tumor cells stimulate PSCs, promoting secretion of collagen, fibronectin, and α-SMA, contributing to a stiff and hypoxic microenvironment that supports cancer growth and invasion.

We help researchers study this dynamic interaction and identify exosomal signals that mediate pro-fibrotic reprogramming.

Exosomes in Liver Pre-metastatic Niche Formation

Studies show that pancreatic cancer-derived exosomes selectively target hepatic Kupffer cells and induce TGF-β and fibronectin production, thereby recruiting bone marrow-derived macrophages and neutrophils to establish a metastatic niche.

Our platform allows mechanistic investigation into miRNA-mediated pathways (e.g., miR-21, miR-301a) that orchestrate this process.

Exosome-Mediated Drug Resistance
We support research into how pancreatic exosomes reduce drug efficacy through:
- Delivery of miRNA-155 to inhibit dCK and reduce drug metabolism
- Promotion of EMT through fibroblast-derived exosomes
- Enrichment of anti-apoptotic proteins that protect tumor cells

These studies aid in identifying new targets to reverse resistance mechanisms.
