abm | Zebrafish Testicular Feeder Cells (ZtA6-8) | T2607
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 Wilm’s tumor suppressor marker (WT1). 12 clones were derived and have distinctive properties and are available at abm.
ZtA6-8 is clone 8 derived from the ZtA6 zebrafish testicular cells. Strong expression of WT1 and Sox9a were observed. However, the ZtA6-8 cells did not have significant phagocytic activity. The cells are able to support differentiation of germ cells into functional sperm for in vitro fertilization, thus is a suitable tool for research in in vitro fertilization and vertebrate spermatogenesis. Additionally, it may be used for genetic manipulation and studies on testicular biology.
Albino-type (alb-1/alb-1) zebrafish (Danio rerio)
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 mare’s 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
BioSafety Level II
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.
