Celigo evaluates a plant extract for glioblastomoa multiforme treatment

At the Canary Center at Stanford for Early Cancer Detection, investigators studied how AshwaMAX (a steroidal lactone from a winter cherry plant, Withania somnifera, extract) might work as an oral treatment for those with the highly aggressive cancer glioblastoma multiforme (GBM). A heterogeneous disease, non-specific therapies for GBM have proven largely ineffective. Two patient-derived GBM lines (GBM2, GBM39) and one GBM cell line were cultured to create neurospheres that were then exposed to various concentrations of AshwaMAX.  Celigo measured cell proliferation and cell death via Trypan Blue staining. AshwaMAX inhibited the neurospheres at nanomolar concentrations. After additional work in vivo, [...]

Cellometer investigates new treatment paradigm for advanced endometrial cancer

University of North Carolina researchers investigated different techniques for inhibiting the catalytic activity of protein hTERT – a marker of advanced stage endometrial cancer. Endometrial cancer cell lines ECC-1 and Ishikawa were exposed to either siRNA or a small molecule pharmacological inhibitor BIBR1532, in addition to the drug paclitaxel, to see whether inhibiting hTERT provided additional efficacy against these cancer cells. The Cellometer, in combination with propidium iodide and Annexin-V FITC, calculated apoptosis in the various treatment conditions. The hTERT inhibition plus paclitaxel did prove synergistic, reducing cell growth and invasion more than paclitaxel alone. Furthermore, BIBR1532 antagonized cell invasion [...]

Bright field and Fluorescent Image Analysis for Screening Applications using the Celigo Imaging Cytometer

It's White Paper Wednesday! Read our featured white paper: Bright field and Fluorescent Image Analysis for Screening Applications using the Celigo Imaging Cytometer Here, we present whole-well imaging and label-free bright field cell counting applications that allow the Celigo user to generate growth curves over time and monitor cell counts and confluence at the individual well level. These bright field applications permit the screening of drugs altering cell proliferation and growth rate. We also highlight the capacity of the Celigo to image large objects making it suitable for analysis of large structures such as embryoid bodies, tumor spheres or small [...]
