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.
Applications	This cell line is used to evaluate the bioactivity of recombinant human bone morphogenetic protein-2 (rhBMP-2).
Storage Conditions	liquid nitrogen vapor phase

Derivation	Cells from W++ mouse bone marrow were cloned by limiting dilution to obtain the W-20-17 cell line. RefThies RS. Recombinant human bone morphogenetic protein-2 induces osteoblastic differentiation in W-20-17 stromal cells. Endocrinology 130: 1318-1324, 1992. PubMed: 1311236
Genes Expressed	alkaline phosphatase induced by recombinant human bone morphogenetic protein-2 (rhBMP-2) RefThies RS. Recombinant human bone morphogenetic protein-2 induces osteoblastic differentiation in W-20-17 stromal cells. Endocrinology 130: 1318-1324, 1992. PubMed: 1311236
Cellular Products	alkaline phosphatase induced by recombinant human bone morphogenetic protein-2 (rhBMP-2) RefThies RS. Recombinant human bone morphogenetic protein-2 induces osteoblastic differentiation in W-20-17 stromal cells. Endocrinology 130: 1318-1324, 1992. PubMed: 1311236
Comments	Cells used in the W-20-17 assay should not be carried in continuous culture. A working cell bank should be prepared with approximately 5 x 10⁵ cell/mL. Cells should be thawed before each assay. Recombinant human bone morphogenetic protein-2 (rhBMP-2) increased alkaline phosphatase activity in W-20-17 cells in a dose-responsive manner without an effect on proliferation. RefThies RS.

Complete Growth Medium	Dulbecco's modified Eagle's medium with 4 mM L-glutamine adjusted to contain 1.5 g/L sodium bicarbonate and 4.5 g/L glucose, 90%; heat-inactivated fetal bovine serum, 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. Subculture every 3 to 4 days. Remove and discard culture medium. Briefly rinse the cell layer with 0.25% (w/v) Trypsin-053mM EDTA solution to remove all traces of serum which contains trypsin inhibitor. 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. Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting. Add appropriate aliquots of the cell suspension to new culture vessels. Incubate cultures at 37°C. Subcultivation Ratio: 1:4 to 1:6 Medium Renewal: At subculture. 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.
Cryopreservation	Culture medium 95%; DMSO, 5%. Cell culture tested DMSO is available as ATCC Catalog No. 4-X.
Culture Conditions	Temperature: 37°C
