Phenotype: testis star expression decreased amount, abnormal
Note: This phenotype statement describes a gene expression or antibody labeling pattern. Anatomy terms are combined with a gene or antibody and phenotype quality.
EXPRESSION ANATOMY:
Name: testis
Synonyms: testes
Definition: Male reproductive organ. Adult zebrafish testes are paired organs forming elongated structures, internally organized into tubules. These tubules are formed by seminiferous epithelium containing cysts of spermatogonia and spermatocytes surrounded by somatic support cells, called Sertoli cells. Cysts are arranged around a lumen containing spermatozoa that is connected to the efferent ducts. The interstitial regions between the tubules contain the steroid-producing Leydig cells, connective tissue, and blood vessels.
