GEISHA is the online repository of in situ hybridization and corresponding metadata for genes expressed in the chicken embryo during the first six days of development. GEISHA is a public resource funded by the National Institutes of Health, USA.

Access gene expression information in the following ways:

• Use Browse to view information according to embryo stage, anatomical location, gene name or ID, citation keyword, or by multiple parameters
  
  
• Use QuickSearch to query by gene name, anatomical
  location, embryo stage, GEISHA ID, citation keyword, Gene ID,
  or Gene Ontology keywords.
  
  
• Use Gene Family QuickSearch to rapidly access information about genes that have regulatory functions during development.
