Towards a "Testis in a Dish": Generation of Mouse Testicular Organoids that Recapitulate Testis Structure and Expression Profiles.

ABSTRACT: The testis is responsible for sperm production and androgen synthesis. Abnormalities in testis development and function lead to disorders of sex development and male infertility. Currently, no in vitro system exists for modelling the testis. Here, we generated testis organoids from neonatal mouse primary testicular cells using transwell inserts and show that these organoids generate tubule-like structures and cellular organization resembling that of the in vivo testis. Gene expression analysis of organoids demonstrates a profile that recapitulates that observed in in vivo testis. Embryonic testicular cells, but not adult testicular cells are also capable of forming organoids. These organoids can be maintained in culture for 8-9 weeks and shows signs of entry into meios
