BioVector® A99 Human Aortic Smooth Muscle Cell Line
1. Background and Origin
A99 is a cell line derived from human aortic smooth muscle tissue. This cell model is used to study cardiovascular disease mechanisms, atherosclerosis, vascular injury response, neointimal hyperplasia, vascular remodeling, and smooth muscle cell signal transduction.
2. Biological Characteristics
Tissue Origin: Human Aorta Smooth Muscle
Growth Properties: Adherent, long spindle shaped, forms a hill and valley pattern at full confluence
Cell Markers:
alpha Smooth Muscle Actin
Calponin and SM22 alpha
Applications: Vascular smooth muscle cell proliferation, migration, phenotypic switching, atherosclerosis research, and cardiovascular drug screening
3. Culture and Handling Protocols
Culture Medium Formulation
Basal Medium: High Glucose DMEM or specialized Smooth Muscle Growth Medium
Serum and Additives: 10 percent Fetal Bovine Serum (FBS)
Antibiotics: 100 U/mL Penicillin and 100 ug/mL Streptomycin
Incubation and Subculture Guide
Incubation Conditions: 37 degrees Celsius, 5 percent CO2, humidified atmosphere
Confluence Management: Maintain cell density between 30 percent and 85 percent to prevent premature senescence or phenotypic shift
Subculture Procedure:
Remove spent media and wash twice with PBS.
Add 0.25 percent Trypsin-EDTA and incubate at 37 degrees Celsius for 2 to 4 minutes until cells detach.
Neutralize with complete medium and mix gently.
Centrifuge at 200 x g for 5 minutes, resuspend, and seed at a ratio between 1:2 and 1:4.
