WebCells at high cell density are more densely stained by Oil Red O than the cells at low cell density. Oil Red O staining also increases with culture time. Although the density of the lipid vacuoles and Oil Red O staining increase with the increase of cell density, the MSCs at all cell densities differentiate into adipocyte-like cells.
The types of bioprocesses for which fed-batch culture is effective can be summarized as follows: 1. Substrate inhibition Nutrients such as methanol, ethanol, acetic acid, and aromatic compounds inhibit the growth of microorganisms even at relatively low concentrations. By adding such substrates properly lag-time can be shortened and the inhibition of the cell growth markedly reduced. small sports grantsWeb14 de abr. de 2024 · High cell density cultivation for H C fragment expression.
