| Derivation |
The C2BBe1 (brush border expressing) cell line was cloned in 1988 from the Caco-2 cell line (ATCC® HTB-37™) by limiting dilution.
The clone was selected on the basis of morphological homogeneity and exclusive apical villin localization. |

| Receptor Expression |
epidermal growth factor (EGF) |
| Comments |
The clone was selected on the basis of morphological homogeneity and exclusive apical villin localization.
C2BBe1 cells form a polarized monolayer with an apical brush border (BB) morphologically comparable to that of the human colon.
Isolated BB contained the microvillar proteins villin, fimbrin, sucrase-isomaltase, BB myosin-1 and the terminal web proteins fodrin and myosin II.
The cells express substantial levels of BB myosin I similar to that of the human enterocyte.
Although clonal, and far more homogeneous than the parental Caco-2 cell line with respect to BB expression, these cells are still heterogenous for microvillar length, microvillar aggregation, and levels of expression of certain BB proteins.

| 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: 0.01 mg/ml human transferrin; fetal bovine serum to a final concentration of 10%.
|
| Subculturing |
Volumes are given for a 75 cm2 flask. Increase or decrease the amount of dissociation medium needed proportionally for culture vessels of other sizes.
- Remove and discard culture medium.
-
Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum that 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.
Subculture at 85% of confluence (about every 5 to 7 days).
Subcultivation Ratio: A subcultivation ratio of 1:6 to 1:10 is recommended
