Combining extracellular matrix 3D Cell Culture with CometChip® technology for genetic toxicology testing with in vitro skin models.
DermaChip® is a new high throughput assay technology that allows scientists, for the first time, to reliably measure the genotoxic risk of a whole range of environmental agents (including cleaning agents, household products and industrial chemicals as well as cosmetics) to our skin.
The Problem
It has been shown that risk assessment data from the micronucleus assay together with traditional comet analysisof cells isolated from treated 3D skin culture models is a better predictor of skin toxicity compared to the standard

DermaChip® is a new high throughput assay technology that allows scientists, for the first time, to reliably measure the genotoxic risk of a whole range of environmental agents (including cleaning agents, household products and industrial chemicals as well as cosmetics) to our skin.
The Problem
It has been shown that risk assessment data from the micronucleus assay together with traditional comet analysisof cells isolated from treated 3D skin culture models is a better predictor of skin toxicity compared to the standard
battery of in vitro toxicity assays. However, in some in vitro models, unacceptable backgrounds were observed as a function of skin preparation. This may be a result of the stage of differentiation of the skin and associated DNA damage when assays are performed. One would expect higher comet backgrounds in cells migrating toward the stratum corneum.
The Solution
DermaChip® combines extracellular matrix 3D Culture technology with CometChip® technology to provide a unique platform able to specifically isolate basal keratinocytes for genetic toxicology testing using in vitro skin models. The elimination of cells migrating to the stratum corneum, that potentially harbour damaged DNA from the analysis, reduces the background for some 3D models.
