β¦ Synopsis
A novel serum-free medium for the cultivation of Vero cells on microcarriers was developed,which composed of the 1: 1 mixture of Dubecco's Modified Eagle Medium : Nutrient Mixture F12, bovine serum albumin(BSA) or human serum albumin(HSA), epidermal growth factor(EGF), gelatin and Dbiotin. Both BSA and EGF were effective on cell growth, adhesion and spreading. Further addition of gelatin and biotin led to the enhanced cell adhesion and spreading without growth promoting activity. The serum-free medium was suitable for the cultivation of vero cells on several different microcarriers with cell density reached over 3x106cells/ml.

We have established a novel cell line from a Vero cell derivative that is useful for expression of exogenous genes and protein production. Parental Vero-317 cells can grow in biotin-containing Eagle's MEM without supplements. By transforming this cell line with replication origin-defective SV40 DNA,
The attachment characteristics of the Vero cell line on microcarriers has been found to be influenced by the serum proteins. Significant quantities of serum proteins were found to be adsorbed on the carrier surface, which resulted in decreased exchange capacity and a lower attachment rate constant.
