Age: embryo, 7 days gestation
Comments:Neuroretinas were dissected from normal quail embryos, dissociated and immortalized by infection with Rous sarcoma virus (RSV) mutant ts NY-68 to establish NR cell lines. [48962 ]
Cells were subsequently cloned after 18 months in culture to establish the cloned cell line QNR/K2. [48962 ]
Neuroretina (NR) is an evagination of the central nervous system (CNS) which is composed of photoreceptors; glial (Muller) cells; horizontal, bipolar, amacrine; and ganglion neuronal cells. [48961 ]
The QNR/K2 cell line displays properties of Muller (astroglia) cells.
The cells were able to respond to electrical stimulation by producing action potentials which were inhibited by 10(-7) M tetrodotoxin. [48962 ]
The specific activity of glutamic acid decarboxylase (GAD), the enzyme responsible for the synthesis of the neurotransmitter gamma-aminobutyric acid, was high. [48962 ]
QNR/D cells (ATCC CRL-2532 ) and QNR/K2 cell (ATCC CRL-2533 ) were transplanted into chicken embryo eyes. Implanted QNR/D cells migrate only to the retinal ganglion and amacrine cell layers and project neurites in the plane of retina. [48964 ]
In contrast, QNR/K2 cells migrate through the ganglion and amacrine layers, locate in the inner nuclear layer, and project processes across the retina. [48964 ]
Propagation: ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Temperature: 39.0°C
Subculturing: Protocol: Remove medium, and rinse with 0.25% trypsin, 0.53 mM EDTA solution. Remove the solution and add an additional 1 to 2 ml of trypsin-EDTA solution. Allow the flask to sit at room temperature (or at 37C) until the cells detach. Centrifuge the cell suspension at 1000 rpm for 10 minutes, resuspend the pellet in fresh medium, aspirate and dispense into new flasks.
Subcultivation Ratio: A subcultivation ratio of 1:3 is recommended
Medium Renewal: Every 2 to 3 days
Preservation: Freeze medium: Complete growth medium 95%; DMSO, 5%
Storage temperature: liquid nitrogen vapor phase
Related Products:Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2002
recommended serum:ATCC 30-2020
