Disease
Tuberous sclerosis
Age
36 years
Gender
Male
Applications
This cell line can be used to study signal transduction and drug efficiency in tuberous sclerosis.
Storage Conditions
Liquid nitrogen vapor phase
Karyotype
This cell line is of male origin and 1/2 to 2/3 of the total cell population is pseudodiploid, the rest of the cells fall in the tetraploid range. Consistent cytogenetic changes include chromosome 10 and 19 aberration, and chromosome 4 monosomy. Some cells showed loss of the Y chromosome and many of the examined cells contained random chromosomal aberrations. UMB1949 cells have a defined 5bp deletion in exon 33 of tuberin (Tsc2) and mutations in tuberin (and/or hamartin) cause tuberous sclerosis.
Images
Derivation
The UMB1949 cell line was established by sequential introduction of the SV40 large T antigen and human telomerase into human angiomyolipoma cells. 
Antigen Expression

Antigen expression: positive for epithelial marker pan-cytokeratin (immunocytochemistry)

Comments

Angiomyolipomas are benign tumors of the kidney which originate from putative perivascular epithelioid cells that may undergo differentiation into cells with features of melanocytes, smooth muscle or fat cells. 


Complete Growth Medium
The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Subculturing
Volumes used in this protocol are for 75 cm2 flasks; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.
  1. Remove and discard culture medium.
  2. Briefly rinse the cell layer with Ca++/Mg++ free Dulbecco's phosphate-buffered saline (D-PBS) or 0.25% (w/v) Trypsin - 0.53 mM EDTA solution to remove all traces of serum which contains trypsin inhibitor.
  3. Add 1.0 to 2.0 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. An inoculum of 1.5 X 104 to 2.5 X 104 viable cells/cm2 is recommended.
  6. Incubate cultures at 37°C. Subculture when the cell concentration is between 5 X 104 to 7 X 104 cells/cm2.
Subcultivation ratio: A subcultivation ratio of 1:3 to 1:5 is recommended.
Medium renewal: Every 2 to 3 days

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.
