ZtA6 cells are derived from spontaneous tumor-like hypertropheied testis isolated from albino-type (alb-1/alb-1) zebrafish. Clones were analyzed for the expression of the Sertoli cell marker (Sox9a), the germ cell marker (Vas), and the Wilms tumor suppressor marker (WT1). 12 clones were derived and have distinctive properties and are available at abm. ZtA6-2 is clone 2 derived from the ZtA6 zebrafish testicular cells. ZtA6-2 cells express Sox9a and WT1 markers, and the ability to undergo phagocytosis. Functionally it was able to support the growth and prolong the vas expression in germ cells. Clone 2 may be used as a source of homogenous mRNA and protein to assess, a source of a homogenous cell line for experimental genetic manipulation, and to aid in the research of spermatogenesis in a zebrafish model.

Propagation
Grow cells in T25 gelatin-coated flasks (TM063) with the following conditions. The base medium for this cell line is L-15 medium (ThermoFisher Scientific). To make the completed growth medium, add the following components to the base medium at the following final concentrations: 5 IU/ml human chorionic gonadotropin (Sigma), 2 IU/ml pregnant mares serum gonadotropin (Sigma), 0.2 mg/ml L-arginine (Gibco BRL), 0.02 mg/ml L-aspartic acid (Gibco BRL), 0.015 mg/ml L-histidine (Gibco BRL), 0.0725 mg/ml L-lysine HCl (Gibco BRL), 0.02 mg/ml L-proline (Gibco BRL), 0.5% bovine serum albumin (5% w/v stock solution, BSA fraction V, Sigma), 1% Hepes (Sigma), fetal bovine serum (TM999) to a final concentration of 3%, and Penicillin/Streptomycin Solution (G255) to a final concentration of 1%. Atmosphere: air: 100%, Temperature: 28.0°C. To prepare as feeder cells: Treat with 10 µg/ml mitomycin C in L-15 for 5 hours before plating for use as feeder cells for further experimentation.

Quality Control
1) Phagocytic activity was analyzed via the ability to internalize polystyrene beads; 2) RT-PCR was used to assess the presence or absence of WT1, Vas, and Sox9a markers; 3) Functionality test was performed to determine the ability to support male germ cells when co-cultured as feeder cells.
