Phenocore, Phenotyping and Pathology Core

Overview of Services

GEMgutAtypiaDysplasiaNSGSFBPit tumor


Mission: The Phenotyping Core promotes functional genomics and other preclinical translational science at Johns Hopkins, by assisting and collaborating in the characterization and use of genetically and phenotypically relevant animal models of disease and gene function, by:

  1. Preclinical research pathology support and collaboration, including anatomic pathology (macroscopic dysmorphology and histopathology), and clinical pathology.
  2. Training and education in animal model pathobiology, evaluation techniques, phenotyping strategies, especially for genetically engineered mice (GEM).

Services/collaborations include:

●               Anatomic Pathology (Preclinical, pre GLP, GLP);

●               Clinical Pathology (Preclinical hematology (CBC), Clinical Chemistry, urinalysis);

●               Body Composition by QNMR (EchoMRITM-100);

●               Faxitron® high resolution radiography;

●               Specimen Photography, macrophotography, photomicroscopy, morphometry;

●               Training in procedures, techniques.

Note: Grant supported (%FTE) collaborations should be developed for large and long term projects involving pathology. 

Pathology support and collaboration frequently involve acquisition, analysis and interpretation of data, as well as contributions to study design, images and manuscript preparation that warrant authorship. Johns Hopkins Policy on authorship should be followed, per:
