Biosafety Icon BSL 2

ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services. It is your responsibility to understand the hazards associated with the material per your organization’s policies and procedures as well as any other applicable regulations as enforced by your local or national agencies.

Cells contain SV40 sequences

ATCC highly recommends that appropriate personal protective equipment is always used when handling vials. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. Upon thawing, the conversion of the liquid nitrogen back to its gas phase may result in the vial exploding or blowing off its cap with dangerous force creating flying debris. Unless necessary, ATCC recommends that these cultures be stored in the vapor phase of liquid nitrogen rather than submersed in liquid nitrogen.

Detailed product information


Specific applications
This cell line can be used for analysis and comparison of mitogenesis (34°C) and differentiation (39°C).


Growth properties
The H19-7 cell line was derived from hippocampi dissected from embryonic day 17 (E17) Holtzman rat embryos and immortalized by retroviral transduction of temperature sensitive tsA58 SV40 large T antigen. H19-7/IGF-IR cells were established by infecting H19-7 cells with a retroviral vector expressing the human type I insulin-like growth factor receptor (IGF-IR). The cells were selected in medium containing puromycin.
17 days gestation
H19-7 cells grow at the permissive temperature (34°C) in epidermal growth factor or serum.

They differentiate to a neuronal phenotype at the nonpermissive temperature (39°C) when induced by basic fibroblast growth factor (bFGF) in N2 medium (DMEM-high glucose medium with supplements).

At 39°C, expression of the human IGF-IR in H19-7 cells induces an insulin-like growth factor (IGF) I dependent differentiation. The cells extend neurites and show increased expression of NF68.

H19-7/IGF-IR cells express the IGF-IR protein. IGF-IR is known to send two seemingly contradictory signals inducing either cell proliferation or cell differentiation, depending on cell type and/or conditions.

This cell line does not express detectable levels of the SV40 T antigen.

Handling information

Unpacking and storage instructions
  1. Check all containers for leakage or breakage.
  2. Remove the frozen cells from the dry ice packaging and immediately place the cells at a temperature below ­-130°C, preferably in liquid nitrogen vapor, until ready for use.
Complete 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: 0.2 mg/ml G418
  • 0.001 mg/ml puromycin
  • fetal bovine serum to a final concentration of 10%
  • Temperature
    95% Air, 5% CO2
    Handling procedure
    To insure the highest level of viability, thaw the vial and initiate the culture as soon as possible upon receipt. If upon arrival, continued storage of the frozen culture is necessary, it should be stored in liquid nitrogen vapor phase and not at -70°C.  Storage at -70°C will result in loss of viability.
    Note: Flasks used to propagate these cells must be coated with 0.015 mg/mL poly-l-lysine.

    1. Thaw the vial by gentle agitation in a 34°C water bath. To reduce the possibility of contamination, keep the O-ring and cap out of the water.  Thawing should be rapid (approximately 2 minutes).
    2. Remove the vial from the water bath as soon as the contents are thawed, and decontaminate by dipping in or spraying with 70% ethanol. All of the operations from this point on should be carried out under strict aseptic conditions.
    3. Transfer the vial contents to a centrifuge tube containing  9.0 mL complete culture medium and spin at approximately 125 x g for 5 to 7 minutes.
    4. Resuspend cell pellet with the recommended complete medium (see the specific batch information for the culture recommended dilution ratio) and dispense into a new coated culture flask.
    5. Incubate the culture at 34°C in a suitable incubator.  A 5% CO2 in air atmosphere is recommended if using the medium described on this product sheet.
    Subculturing procedure
    Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.
    Note: Flasks used to propagate these cells must be coated with 0.015 mg/mL poly-l-lysine. Cover the surface of the vessel with poly-l-lysine solution for 5 minutes, remove, and let dry.

    1. Remove and discard culture medium.
    2. Briefly rinse the cell layer with 0.25% (w/v) Trypsin-0.53 mM EDTA solution to remove all traces of serum that 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 34°C.

    Subculture Ratio: 1:3 to 1:5
    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.
