A single-cell RNA atlas of freshly isolated Salmo salar testis resolves somatic and germ cell populations across spermatogenesis stages, enabling direct mapping of cultured states.
- Why it matters: Reproductive biotechnologies in aquaculture need reliable in vitro spermatogenesis, but farmed fish culture systems are poorly defined and lack a native cell-type reference.
- What they did: The study built the atlas from primary testis cells, then cultured cells for 14 days under proliferation- or differentiation-oriented media and performed single-cell RNA sequencing.
- The result: Proliferation media with EGF and IGF increased spermatogonial populations, basal medium favored Sertoli cell survival, differentiation media failed to shift states, and Sertoli cells in vitro lost canonical markers and showed stress programs.
