For study of Schwann cell biology, diseases and tumors. These cells are invaluable tools for dissecting the processes contributing to the formation of neurofibromas and possibly other diseases, and the development of disease models and therapeutics.

The collection contains “normal” (wild-type) NF1(+/+),  NF1(+/-) (heterozygous), and NF1(-/-) homozygous (neurofibroma derived) human Schwann cell lines.  (NOTE: Cell-lines generated under auspices of the lab of Dr. Peggy Wallace, University of Florida, with funding support by the Neurofibromatosis Therapeutic Acceleration Program (NTAP) at Johns Hopkins University)

A team of researchers from the University of Florida, the National Center for Advancing Translational Sciences (NCATS), and Sage Bionetworks with support from the Neurofibromatosis Therapeutic Acceleration Program (NTAP) at Johns Hopkins, have developed and characterized a set of immortalized patient derived plexiform neurofibroma Schwann cells in an initial effort to create a series of cells that represent the genetic diversity of human plexiform tumors.¹

Through exogenous expression of human telomerase reverse transcriptase (hTERT) and murine cyclin-dependent kinase (mCdk4) using retroviral (and subsequently lentiviral) vectors carrying the hTERT and mCdk4 genes, normal (NF1 wild-type, +/+), neurofibroma-derived Schwann cells that were heterozygous (+/-) for NF1 mutation, and homozygous (-/-) for NF1 mutation, were immortalized. ¹

This product, and other immortalized cells from the collection, have undergone in-depth characterization and authentication.

• Oncogenes: transduced with mCdk4 cDNA and hTERT
• Neurofibroma Schwann cell culture transduced with human telomerase (TERT) cDNA and mouse Cdk4 cDNA in lentivirus vectors (no selection), to immortalize the cells.  

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.

• 56 mL FBS (ATCC 30-2020) 
• 5.6 mL L-glutamine from stock 200mM (ATCC 30-2214)

To ensure 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.  

1. Thaw the vial by gentle agitation in a 37°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). It is important to avoid excessive alkalinity of the medium during recovery of the cells.  It is suggested that, prior to the addition of the vial contents, the culture vessel containing the complete growth medium be placed into the incubator for at least 15 minutes to allow the medium to reach its normal pH (7.0 to 7.6). pH (7.0 to 7.6).
5. Incubate the culture at 37°C in a suitable incubator.  A 5% CO₂ in air atmosphere is recommended if using the medium described on this product sheet.

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.
   Cultures can be established between 1.5 x 10⁴ and 3.0 x 10⁴ viable cells/cm².
6. Incubate cultures at 37°C.
