TLDR
It is shown that CAFs are an important IL-6 source and that anti-IL-6 receptor antibody suppressed angiogenesis and inhibited tumor-stroma interactions, and CAFs contribute to drug-resistance acquisition in cancer cells.Abstract:
Cancer tissues are composed of cancer cells and the surrounding stromal cells (e.g., fibroblasts, vascular endothelial cells, and immune cells), in addition to the extracellular matrix. Most studies investigating carcinogenesis and the progression, invasion, metastasis, and angiogenesis of cancer have focused on alterations in cancer cells, including genetic and epigenetic changes. Recently, interactions between cancer cells and the stroma have attracted considerable attention, and increasing evidence has accumulated on this. Several researchers have gradually clarified the origins, features, and roles of cancer-associated fibroblasts (CAFs), a major component of the cancer stroma. CAFs function in a similar manner to myofibroblasts during wound healing. We previously reported the relationship between CAFs and angiogenesis. Interleukin-6 (IL-6), a multifunctional cytokine, plays a central role in regulating inflammatory and immune responses, and important roles in the progression, including proliferation, migration, and angiogenesis, of several cancers. We showed that CAFs are an important IL-6 source and that anti-IL-6 receptor antibody suppressed angiogenesis and inhibited tumor-stroma interactions. Furthermore, CAFs contribute to drug-resistance acquisition in cancer cells. The interaction between cancer cells and the stroma could be a potential target for anti-cancer therapy.read more

TL;DR: Applying multimodal intersection analysis to primary pancreatic tumors, it is found that subpopulations of ductal cells, macrophages, dendritic cells and cancer cells have spatially restricted enrichments, as well as distinct coenrichments with other cell types.

Blood Vessel Formation: What Is Its Molecular Basis?
TL;DR: It is only when students learn that these vessels with their proper diameters and branches are formed in the embryo, mostly before the heart starts beating, that students begin to appreciate the true complexity of the genetic program that governs the development of the vascular system.

TL;DR: In this alternative model of tumorigenesis, the epithelial cancer cells instruct the normal stroma to transform into a wound-healing stroma, providing the necessary energy-rich micro-environment for facilitating tumor growth and angiogenesis, explaining its powerful predictive value.

TL;DR: Experiments in which the in vitro overexpression of FSP1 cDNA in tubular epithelium is accompanied by conversion to a mesenchymal phenotype are observed, as characterized by a more stellate and elongated fibroblast- like appearance, a reduction in cytokeratin, and new expression of vimentin.

TL;DR: Data indicate that stellate cells have an important role in supporting and promoting pancreatic cancer, and the presence of HPSCs in tumors increases the growth and metastasis of these cells.
