Obtain Pure Malignant Cells with the New Cancer Cell Culture Toolkit
The new cancer cell culture toolkit from PromoCell aids the growth of both primary tumors as well as established cells lines, explains Dr. Hagen Wieland during the AACR (American Association for Cancer Research) Annual Meeting in Chicago…. -
Extracellular vesicles in cancer therapy
EVs in tumor development Extracellular vesicles (EVs), including exosomes, play a crucial role in tumor biology. Alongside modulating the tumor microenvironment and contributing to the malignant cascade (angiogenesis, the host immune system response, and metastasis), EVs are involved in chemoresistance. Docetaxel in prostate cancer, for example, may transport mRNA encoding drug-resistant proteins or carry miRNA to recipient cells and trigger the expression of specific target genes…. -
3D cancer model
De-skilling 3D tumor models Tissue-engineered 3D cancer models have grown in popularity with recent advances in cancer research. 3D models are more biomimetic than 2D cell monolayers cultured on tissue culture plastic. Examples are spheroids, tumorspheres, organoids, PDX and lately, tumoroids, which differ by origin (cell line or patient-derived), size, the complexity of cellular architecture and tumor environment…. -
Cancer stem cell selection
Advance cancer stem cell culture Cancer stem cells (CSCs) are a specific and small subpopulation of tumor cells. Despite their low number, they drive tumor initiation, influence tumor progression, and cause metastasis and relapse. Increased cancer stem cell populations have been shown to reflect the aggressiveness and therapy-resistant phenotype of the tumor…. -
Primary Cancer Cells: A Culture System Opens the Door to Individualized Therapy
Self-destruction of the body: Cancer turns normal body cells into their malignant counterpart that wants to keep on replicating by any means. Understanding the individual disease offers the potential for more effective therapies with fewer side effects. The new PromoCell Primary Cancer Culture System allows researchers to generate high-fidelity in vitro models of primary tumors…. -
CSC therapy – towards new opportunities
CSCs as therapeutic targets Cancer stem cells (CSCs) are a small subset of tumor cells that are able to evade anti-tumor defense mechanisms and suppress anti-tumor immune responses by releasing soluble immunosuppressive factors, such as anti-inflammatory cytokines. CSCs appear to have multiple strategies to escape immunological destruction, including the acquisition of genetic and non-genetic alterations that reduce immune recognition,… -
Malignant mesothelioma: Paving the way for new therapies
From bench to bedside and back: This is the direction of malignant mesothelioma research. Yet to understand the biology of this particular type of cancer, more basic insights are still needed. And translating that knowledge into new therapies is extremely important, as only limited therapeutic options exist so far. Molecular needles that cross the lung epithelium: That’s how asbestos – often in form of dust – enters lung tissue (Carbone et al.,… -
Advancements and applications of tumor organoids in cancer research
Organoid models of patient-specific tumors are transforming our understanding of cancer heterogeneity and its implications for personalized medicine. In this interview with BioTechniques, our experts, Janina Moros, Alexander Trampe and Zinnia Noor, discuss the benefits of tumor organoids, how to establish and culture them and their applications across different areas of cancer biology…. -
Tumor microenvironment
The role of CSCs and the TME Cellular interactions in the tumor microenvironment (TME) significantly influence cancer progression and drug response. The efficacy of immunotherapies has triggered increased interest in the tumor immune microenvironment. Therefore, robust experimental systems are needed to enable researchers to model patient-specific interactions between tumor cells and immune cells…. -
EV cancer treatment cell media: Importance and challenges
Since the birth of extracellular vesicle (EV) cancer treatment, EVs have provided invaluable biomarkers for cancer diagnosis and stable drug vehicles for treatment delivery. Correct isolation and suitable cell culture growth media are indispensable in producing effective, non-toxic EV cancer treatments…. -
A Home for Cancer Stem Cells: 3D Tumorspheres
Many scientists working in oncology focus on cancer stem cells (CSCs). Targeting these cells specifically could improve cancer therapy significantly. Because CSCs rely heavily on their environment, three-dimensional cultivation offers the unique opportunity to better understand this interaction. We talked to two scientists working in this field of cancer research. In the human body,… -
Teaching the body to fight tumors using cancer immunotherapy
Selected as the 2013 “Breakthrough of the Year” by Science magazine, cancer immunotherapy shows a completely new way to treat malignancies by using the body’s own immune system, and not by targeting the tumor itself. This cutting-edge area of research and therapy has shown very promising results. However, further investigation is needed to turn immunotherapy into a cancer therapy that can be broadly applied….
