Service Pipeline
Our service pipeline supports more humane animal research and aims to reduce the cost of animal testing. We do this by introducing a Tier-1 phase of testing where animal-test free experimental models are used.
This follows the principle of 3Rs by the NC3Rs: Replacement, Reduction and Refinement.
While in vitro tests are an attractive alternative for animal testing, they can never replace full body effects of chemicals. In living organisms, cells and organs in the body communicate to each other, for example by hormones or other signalling molecules.
Additional 3R tests therefore include in vivo test systems, small organisms, like the 1-mm sized nematode Caenorhabditis elegans.
Our strategy allows us to pre-screen large amounts of compounds in a high-throughput fashion, to select the most promising compounds for product development pipelines. In addition, we can gain insight in how compounds cause their effects, in order to help to improve compound/drug design procedure.
Step-wise study design
The Experimental Model
Vivaltes’ core strength is the experimental model organism C. elegans, a 1-mm long transparent nematode.
These animals fall outside the definition of animals included in the animal testing law, and are thus considered animal test-free.
C. elegans was first used as a model organism in 1963 and the acquired knowledge made an invaluable contribution to the fields of developmental biology and genetics. The application of C. elegans in the field of toxicology is rising, evident from the increasing number of publications.
The C. elegans body plan
Model Strengths
- C. elegans is a multicellular organism, it has neuronal, motor, digestive, and reproductive systems, endocrine signaling, and sensory/behavioral responses to stimuli, which are not present in cell and tissue cultures.
- The organism has been studied for over 55 years, there is thus a large body of knowledge to make use of.
- Humans and C. elegans have a common ancestor, many key pathways are conserved.
- The ease of handling allow multiple concentrations and exposure times to be assessed simultaneously.
- The rapid lifecycle allows for low-dose lifespan and multigeneration testing in a couple of weeks rather than years.
- Multiple types of toxicity ranking screens have demonstrated good correlation of endpoints in C. elegans to rat LD50s, with C. elegans data and mouse data predicting toxicity ranking in rat equally well.

News
Save the Date!
February 17, 2020
Save the Date! On May 15, 2020, Vivaltes together with Schenkeveld, Ockham, Greenport, and the NH Food team are organizing the Novel Foods event that takes place in Alkmaar. The speakers are experts of novel foods, test methods. and laws and regulations. The knowledge event is for farmers, horticulturists, seed breeders, developers of new foods and other professionals including regulators who are involved in novel foods.
Top team, all those C. elegans experts together!

Hot peppers: a new weapon in the fight against obesity?
December 8, 2018
Hot peppers contain a substance that causes you to burn more fat. In that way, one can continue to eat the same and still lose weight. In America a medicine is being made from hot peppers. Dutch researchers want to make a food supplement or even a whole new pepper variety. Vivaltes is working on the subject with a team of researchers.
