| Age | 112 days gestation fetus |
| Applications | 6E7 sequences were detected by PCR in cells at passage 18.Major Histocompatibility Complex class I or II molecules were not expressed on these cells, but PCR analyses revealed presence of the genes for directing synthesis of HLA antigens. Major Histocompatibility Complex class I or II molecules were not expressed on these cells, but PCR analyses revealed presence of the genes for directing synthesis of HLA antigens. |

| Comments | After 50 population doublings, the cells continue dividing and retain cuboidal morphology. E6E7 sequences were detected by PCR in cells at passage 18. Major Histocompatibility Complex class I or II molecules were not expressed on these cells, but PCR analyses revealed presence of the genes for directing synthesis of HLA antigens.Major Histocompatibility Complex class I or II molecules were not expressed on these cells, but PCR analyses revealed presence of the genes for directing synthesis of HLA antigens. |
| Complete Growth Medium | These cells are grown in Keratinocyte-Serum Free Medium (Gibco 17005-042) with added Keratinocytes Supplements (Gibco 37000-015) including Bovine Pituitary Extract (BPE; Gibco 13028-014) and human recombinant epidermal growth factor (EGF; Gibco 10450-013) further supplemented with:
Do not filter the complete medium. This medium is formulated for use with a 5% CO2 in air atmosphere. |
| 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.
Subcultivation Ratio: 1:3 to 1:6 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. |

Fetal skin was digested with a collagenase-trypsin mixture. The digestion products were plated on collagen- fibronectin-BSA coated flasks in Keratinocyte Serum-Free Medium with epidermal growth factor and bovine pituitary extract. Passage 3 cells were transformed with a retrovirus vector (LXSN16E6E7 produced by ATCC CRL-2203) in the presence of polybrene. This lines has a rare human G6PD phenotype (A-B).
