The potential role of the pseudobranch of molly fish (Poecilia sphenops) in immunity and cell regeneration [PDF]

Scientific Reports, 2023
The pseudobranch is a gill-like structure that exhibits great variations in structure and function among fish species, and therefore, it has remained a topic of investigation for a long time.

Structural and Functional Aspects of the Spleen in Molly Fish Poecilia sphenops (Valenciennes, 1846): Synergistic Interactions of Stem Cells, Neurons, and Immune Cells [PDF]

Biology, 2022
In fish, the spleen is the prime secondary lymphoid organ. It has a role in the induction of adaptive immune responses, in addition to its significance in the elimination of immune complexes.

Unraveling Spermatogenesis in Molly Fish (Poecilia sphenops): An Integrative Study of Testicular Ultrastructure and Immunohistochemistry [PDF]

Veterinary Sciences
Spermatogenesis in teleosts is essential for reproductive function; however, it varies considerably among species. The testis of the viviparous molly fish (Poecilia sphenops) was examined using both ultrastructural and immunohistochemical methods.
