Designing high-content tumor spheroid drug screening using high-throughput image cytometry

Solid tumor biology has become a critical step in accessing the potency of many cancer drugs. 3D spheroids and organoids can provide measurements such as size differences under drug conditions or metabolism and diffusion rates critical to drug development.

A rapid method to establish potential molecular targets for colorectal cancer progression

The development of targeted molecular therapies is an increasingly popular approach to combat and overcome the limitations of conventional treatments.

Identifying Downstream Candidates for Targeted Molecular Therapy

A fundamental understanding of the molecular mechanisms responsible for the development and progression of RCC will be pivotal in developing next-generation treatment protocols to improve patient outcomes.

Webinar on Demand: Advanced In-vitro Cancer Models to Study Tumor Microenvironment

During this webinar we will highlight a variety of assays to study the tumor microenvironment

Cellometer assists in search to combat tumor radio-resistance

At the University of Luebek (Germany), scientists investigated how a mechanism of tumor hypoxia - Aryl hydrocarbon receptor nuclear translocator (ARNT), a transcription factor also known as hypoxia-inducible factor (HIF)-1β - increases a tumor’s resistance to radiation therapy. ARNT expression was knocked out with siRNA or overexpressed using a plasmid vector in a variety of human tumor cell lines such as Hep3B, MCF-7, 786-Owt, 786-Ovhl, RCC4wt and RCC4vhl before exposure to X-irradiation. The Cellometer and Trypan Blue were used to establish cell counts. Researchers found that a reduction of ARNT expression made all cell lines more susceptible to X-irradiation, whereas [...]

Establishment of Human Ultra-Low Passage Colorectal Cancer Cell Lines Using Spheroids from Fresh Surgical Specimens Suitable for In Vitro and In Vivo Studies

Human primary colon cancer cells digested from tumor used to establish ultra-low passage colorectal cancer cell lines. Cell count and viability were determined by the trypan blue dye exclusion method using a T4 Cellometer (Nexcelom Bioscience LLC, USA). […]

Triptolide Inhibits the Proliferation of Prostate Cancer Cells and Down-Regulates SUMO-Specific Protease 1 Expression

LNCaP and PC-3 cells Cells were gently trypsinized and staining with trypan blue dye. The viable cells were counted using cell counting chamber every 24 h for 7 days. 48 h after transfection, cells were treated with Triptolide for another 48 h. After stained with trypan blue, viable cells were counted using cellometer Auto T4 automated cell counter. […]
