Tumorsphere Formation & Clonogenic Survival

Live cell analysis of tumorsphere formation and clonogenic assays to quantify size and number of formed tumorspheres.

  1. Directly image tumor spheroids in various microwell formats
  2. Non-invasive bright field imaging allows the user to image the same plate over multiple days
  3. Perform a two-color fluorescent viability assay

The Celigo imaging cytometer has been developed to fully automate imaging and analysis of tumorspheres. This automated morphometric analysis tool significantly reduces the time and effort needed to quantify key aspects of 3D spheres including size, growth, growth tracking over time and response to chemotherapeutics.

Celigo software imaging and quantification of tumorsphere

Celigo software displays a plate map, image view of the whole well, and numerical data for the counted spheres. The green fill view indicates counted spheres.

Quantification of Methylene Blue-Stained Clonogenic Colonies in 6-well Plates

MDA-MB-468 colonies stained with methylene blue

MDA-MB-468 colonies were stained with methylene blue 18 days following siRNA knockdown. The plate was imaged on Celigo at 3 um/px.
