With our adaptation procedure, it was possible to obtain cells fully adapted to serum-free media in stationary T-flasks and then enable these adapted cells to grow well in spinner flasks immediately. The spinner "ask with special stirring design proved tO provide favorable culture environment that made it desirable for use in the serum-free cultivation of Tn5 cells even at low seeding density.展开更多

The objective of this research was to study the comparison of Vero cell growth on different types of commercial microcarriers;Cytodex-1, Cytodex-3, Hil-lex? II and Plastic Plus in spinner vessel and two liters bioreactor cultured for 96 hours. Biological performance of the microcarrier in RPMI media showed the preference of Vero cell grew on Cytodex 3 microcarriers with highest maximum viable cell number (2.4 × 105 cells/ml) followed by Cytodex 1, Hillex and Plustic Plus. Vero cell on Cyto-dex-3 data in spinner flask was compared in bioreactor and result showed higher viable cell number in biorector. Thus, this dextran-crosslink gelatin microcarrier (Cytodex 3) provided the best surface for cell attachment and fast proliferation. At the end of this cell growth improvement will be used for virus transfection producing a vaccine in bioreactor.展开更多
