Parameters for MDBK cell growth on microcarriers and BoHV-1 virus production

Growth of fish cell lines on microcarriers.

Microcarrier beads were evaluated as substrates for the propagation of five anchorage-dependent fish cell lines. Growth of rainbow trout gonad (RTG-2) and Atlantic salmon cells was limited on microcarriers maintained in suspension. However, stationary microcarriers were suitable substrates for the growth of RTG-2, AS, Chinook salmon embryo (CHSE-214), and fathead minnow cells. Cell yields range...

Neutralizing antibodies to bovine herpesvirus types 1 (BoHV-1) and 5 (BoHV-5) and its subtypes.

This study was carried out to determine whether the sensitivity of serum neutralization (SN) tests would be affected by the use of distinct subtypes of bovine herpesvirus 1 (BoHV-1) and 5 (BoHV-5) as test challenge viruses. Bovine sera collected from a randomized sample (n=287) were tested in a 24h incubation SN against three type 1 viruses (BoHV-1.1 strains "Los Angeles" (LA) and "EVI 123"; Bo...

Bovine myoblast cell production in a microcarriers-based system

For several tissue engineering applications, in particular food products, scaling up culture of mammalian cells is a necessary task. The prevailing method for large scale cell culture is the stirred tank bioreactor where anchor dependent cells are grown on microcarriers suspended in medium. We use a spinner flask system with cells grown on microcarriers to optimize the growth of bovine myoblast...

Use of human diploid cell MRC - 5, for production of Measles and Rubella virus vaccines

Cell growth on microcarriers: comparison of proliferation on and recovery from various substrates.

Three commercially-important types of cell were grown on four different microcarrier substrates. The cells, which included normal human diploid fibroblasts (MRC-5), primary chick embryo cells and Madin-Darby bovine kidney cells (MDBK), were compared with regard to proliferation on the substrates and with regard to recovery of viable cells from the same substrates. The substrates used included g...
