Applications: yolk protein genes, and permits the analysis of estrogen responsive genes involved in the transport of yolk proteins and other nutrients to the oocyte.
NOTE: tissue culture vessels used to propagate this line must be precoated with 0.1% gelatin.
Vessels prepared in this fashion may be used immediately.
Receptors:LMH/2A细胞 estrogen receptor, positive
Tumorigenic: Yes
Cytogenetic Analysis: triploid; modal number = 116; six marker chromosomes
Comments: LMH/2A is a stably transfected cell line constructed in 1989 by R. Binder from the LMH hepatocellular carcinoma cell line (see ATCC CRL-2117).
By cotransfection with the plasmid pRSVCEO (containing the chicken estrogen receptor gene driven by the Rous sarcoma promoter) and the pRSVNEO plasmid (which confers G418 resistance).
LMH/2A cells express high levels of chicken estrogen receptor.
Apolipoprotein (apoII) gene expression is increased by estrogen 300-fold compared with levels in the low receptor expression parent LMH line.
This cell line is estrogen responsive for the expression of endogenous
yolk protein genes, and permits the analysis of estrogen responsive genes involved in the transport of yolk proteins and other nutrients to the oocyte.
These genes include apolipoprotein B and apoII as well as vitellogenin.
NOTE: tissue culture vessels used to propagate this line must be precoated with 0.1% gelatin.
To prepare the vessels, flood them with gelatin solution, refrigerate for 5 to 10 minutes, and remove the liquid.
Vessels prepared in this fashion may be used immediately.
Propagation: ATCC complete growth medium: Waymouth's MB 752/1 medium, 90%; fetal bovine serum, 10%
Temperature: 37.0°C
Atmosphere: air, 95%; LMH/2A细胞carbon dioxide (CO2), 5%
Subculturing: Subcultivation Ratio: A subcultivation ratio of 1:4 is recommended
Medium Renewal: Every 2 to 3 days
Remove medium, rinse two times with cold 0.25% trypsin, 0.03% EDTA solution. Allow the flasks to sit at room temperature (or incubate at 37C) until the cells detach.
Add fresh culture medium, aspirate and dispense into new culture flasks.
Flasks must be coated with 0.1% gelatin.
Preservation: Culture medium, 95%; DMSO, 5%
