The mission of the Northwestern University Mouse Histology & Phenotyping Laboratory (MHPL) is to assist investigators with tissue histopathology for experimental animal research. The laboratory provides comprehensive histology services for all rodent species (i.e., mouse, rat, etc.) which includes necropsy, phenotyping of organs and tissues, dissection and tissue processing, and one-on-one consultation with investigators. The lab generates unstained paraffin and frozen sections for investigators to be used for special staining and immunohistochemistry (IHC). Pathologist consultation can also be provided to help develop strategies to elucidate phenotypes and gain mechanistic insight regarding the biologic actions of the targeted molecule or the toxicity of exogenously administered substances. In addition, the laboratory provides training opportunities for learning histology techniques and phenotyping analysis.
