| Disease： | Non-malignant myomas |
| Age： | Adult |
| Gender： | Female |
| Storage Conditions： | Liquid nitrogen vapor phase |
| Karyotype： | This is a diploid cell line of female origin. Overall, the karyology is stable with a modal chromosome number of 46 in 57% of the examined cells and a low rate of polyploidy. No consistent structural chromosomal aberrations were found in any of the cells examined. |
| Derivation： | This endometrium cell line was derived from the stromal cells obtained from an adult female with myomas.xa0 The primary stromal endometrium cells were immortalized by infection with supernatant from the packaging cell line pA317-hTERT (Geron Corp.; Menlo Park, CA) which expressed the hTERT and the puromycin resistance genes. |
| Antigen Expression： | The cell line expressesxa0vimentin (Homo sapiens) a fibroblast marker, as determined by flow cytometry, and fibroblast surface protein (FSP, Homo sapiens) as determined by immunocytochemistry. |
| Complete Growth Medium： | A 1:1 mixture of Dulbeccos modified Eagles medium and Hams F-12 medium with 3.1 g/L glucose and 1mM sodium pyruvate and without phenol red (Sigma Cat# D 2906) supplemented with 1.5 g/L sodium bicarbonate, 1% ITS+ Premix (BD Cat# 354352), 500ng/mL puromycin, 90%; charcoal/dextran treated fetal bovine serum (HyClone Cat# SH30068.03), 10%
|
| Subculturing： | Volumes are given for T-75 flasks; proportionally reduce or increase the amount of dissociation medium for culture vessels of other sizes.
Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:6 is recommended
Medium Renewal: Every 2 to 3 daysNote: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 13 in Culture Of Aminal Cells: A Manual of Basic Techniques by R. Ian Freshney, 5th edition, published by Wiley-Liss, N.Y., 2005. |
| Cryopreservation： | Complete growth medium 95%; DMSO 5%. Cell culture tested DMSO is available as ATCC Catalog No. 4-X. |
| Culture Conditions： | Temperature:xa037°C |
| STR Profile： | Amelogenin: X CSF1PO: 10,12 D13S317: 12,13 D16S539: 12,14 D5S818: 8 D7S820: 10 THO1: 7,8 TPOX: 9,11 vWA: 16,18 |
| Population Doubling Level (PDL)： | As part of our quality control, we have tested this cell line for its ability to grow for a minimum of 15 population doublings after recovery from cryopreservation. We have also compared its karyotype, telomerase expression level, growth rate, morphology and tissue-specific markers when first recovered from cryopreservation with that of cells at 10+ population doublings to ensure that there is no change in these parameters and that the cells are capable of extended proliferation. |
