STEMart, a US-based provider of comprehensive services for medical device development, has expanded its biocompatibility testing portfolio by adding the In Vivo Mouse Micronucleus Test. This new service is designed to help manufacturers identify potential genotoxic risks and ensure compliance with international regulatory standards, including ISO 10993-3 and OECD Guideline No. 474.
Environmental mutagens can induce chromosomal mutations through various mechanisms, posing serious health hazards. Genotoxicity assessment is a critical component of chemical safety evaluations, and the in vivo micronucleus test is particularly emphasized. The test identifies substances that cause cytogenetic damage, resulting in micronuclei containing chromosomal fragments or entire chromosomes.
The assay is an in vivo cytogenetic test that analyzes red blood cells from rodent bone marrow to detect damage to chromosomes or the mitotic apparatus caused by chemicals. During erythroblast development into polychromatic erythrocytes in bone marrow, the primary nucleus is expelled, potentially leaving a micronucleus in the cytoplasm. Chromosomal damage appears as minute extra-nuclear bodies visible under an optical microscope. An increased incidence of micronucleated polychromatic erythrocytes (MN PCEs) in treated animals indicates genotoxicity.
With the accelerating pace of medical device innovation, reliable genotoxicity assessment is increasingly important. Based on OECD Guideline No. 474, the in vivo mouse micronucleus test evaluates micronuclei in red blood cells. STEMart now offers this test to detect potential cytogenetic damage caused by medical devices. Manufacturers can conduct testing under GLP or non-GLP conditions to identify mutagens or carcinogens early in development.
STEMart provides comprehensive final reports including methodology, raw data, analysis, and result interpretation, empowering developers to effectively mitigate risks. By offering the test under both GLP and non-GLP conditions, STEMart provides flexibility and scientific rigor to meet global regulatory requirements.
