Organism
Mus musculus, mouse
Tissue
pancreas, alpha cells
培養(yǎng)基
Cell Type
alpha cells
Product Format
frozen
Morphology
epithelial
Culture Properties
adherent, with loosely attached clusters and some single cells in suspension
Biosafety Level
2   [Cells contain Papovavirus (SV40)]

Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.

Disease
adenoma
Applications
The alpha TC1 clone 6 cells are useful for studying many aspects of islet biology, including glucagon biosynthesis and cytokine sensitivity.
Storage Conditions
liquid nitrogen vapor phase
Images
Derivation
Alpha TC1 clone 6 is a pancreatic alpha cell line. It was cloned from the alpha TC1 cell line, which was derived from an adenoma created in transgenic mice expressing the SV40 large T antigen oncogene under the control of the rat preproglucagon promoter.
Receptor Expression
H-2b; H-2d, expressed
Genes Expressed
glucagon
Cellular Products
glucagon
Comments
The parental cell line is less differentiated and produces both glucagon and insulin. Two clonal cell lines, alpha TC1 clone 6 and alpha TC1 clone 9 (ATCC CRL-2350), are more differentiated than the parent line and produce only glucagon RefHamaguchi K, Leiter EH. Comparison of cytokine effects on mouse pancreatic alpha-cell and beta-cell lines. Viability, secretory function, and MHC antigen expression. Diabetes 39: 415-425, 1990. PubMed: 2108069. alpha TC1 clone 6 cells exhibit the most differentiated phenotype and express the highest levels of glucagon. RefHamaguchi K, Leiter EH.

Complete Growth Medium
The base medium for this cell line is Dulbecco's Modified Eagle's Medium, low glucose (Gibco Cat. No. 11885-084). To make the complete growth medium, add the following components to the base medium:
  • Fetal bovine serum (FBS) to a final concentration of 10%
  • HEPES to a final concentration of 15 mM
  • Non-essential amino acids to a final concentration of 0.1 mM
  • Bovine serum albumin to a final concentration of 0.02%
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.
NOTE: Warm all solutions to 37.0°C prior to use
  1. Transfer all medium and floating cells from flask to a 50 mL centrifuge tube.
  2. Adherent cells are removed using Cell Dissociation Buffer (an enzyme free buffer; Invitrogen, Catalog No. 13150-016) diluted 1:5 with Hanks' Balanced Salt Solution. Add 5.0 mL of diluted cell dissociation buffer per 75 cm2 flask and gently rock flask to bathe the cells at room temperature for 1 to 2 minutes.
  3. Allow the flask to remain at room temperature for 1 to 5 additional minutes until cells have detached from the flask.
  4. Firmly tap the flask against palm of hand to dislodge cells.
  5. Add 10.0 mL of fresh medium per 75 cm2 flask and triturate up and down directing the stream along the growth surface of the flask to dislodge the cells and break up some of the clumps.
  6. Transfer these cells to the centrifuge tube from Step 1. Centrifuge at 125 x g  for 5 to 10 minutes. Remove medium and resuspend pellet in fresh complete medium.
  7. Add appropriate aliquots of cell suspension to new culture vessels.
  8. Incubate cultures at 37°C.

Subcultivation ratio: A subcultivation ratio of 1:3 to 1:4 is recommended.
Medium renewal: Every 2 to 3 days.

Cryopreservation
Freeze medium: complete growth medium supplemented with an additional 40% heat-inactivated fetal bovine serum and 5% (v/v) DMSO
Culture Conditions
Temperature: 37°C
Atmosphere: air, 90%; carbon dioxide (CO2), 10%
Name of Depositor
