HUMN, which stands for HUman MicroNucleus, is also known as The International Collaborative Project on Micronucleus Frequency in Human Populations. HUMN was launched in 1997 because of world-wide interest in the application of the micronucleus (MN) method to assess environmental effects on chromosome damage in blood and epithelial tissues in human populations.

Our research is currently focused on human lymphocytes and exfoliated epithelial cells as biomonitors of exposure to toxic substances, and as potential predictors of adverse health effects. Combining the available MN data from a variety of human populations would provide a powerful tool for the evaluation of MN frequencies for public health and epidemiological studies. Laboratories that perform MN studies in human lymphocytes and buccal cells are invited to participate. Currently over 40 labs from all over the world are participating in the different aspects of HUMN.
