Biosafety Level
1

Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.

Disease
sarcoma
Age
embryo, 7 days gestation
Applications
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.
The cells were able to respond to electrical stimulation by producing action potentials which were inhibited by 10(-7) M tetrodotoxin.
The specific activity of glutamic acid decarboxylase (GAD), the enzyme responsible for the synthesis of the neurotransmitter gamma-aminobutyric acid, was high.
Storage Conditions
liquid nitrogen vapor phase
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.
Cells were subsequently cloned after 18 months in culture to establish the cloned cell line QNR/K2.
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.
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.
The specific activity of glutamic acid decarboxylase (GAD), the enzyme responsible for the synthesis of the neurotransmitter gamma-aminobutyric acid, was high.
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.
In contrast, QNR/K2 cells migrate through the ganglion and amacrine layers, locate in the inner nuclear layer, and project processes across the retina.
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%.
Subculturing
Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.
  1. Remove and discard culture medium.
  2. Briefly rinse the cell layer with 0.25% (w/v) Trypsin-0.53mM EDTA solution to remove all traces of serum which contains trypsin inhibitor.
  3. Add 2.0 to 3.0 mL of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes).
    Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37°C to facilitate dispersal.
  4. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting.
  5. Add appropriate aliquots of the cell suspension to new culture vessels.
  6. Incubate cultures at 39°C.

Subcultivation Ratio: 1:3
Medium Renewal: Every 2 to 3 days

Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 10 in Culture of Animal Cells, a Manual of Basic Technique by R. Ian Freshney, 3rd edition, published by Alan R. Liss, N.Y., 1994.
