- How do you think the end results would be affected if the cells were not treated with a hypotonic solution?For most cell types, serum must be added to the media to get cells to grow and proliferate in culture. Nevertheless, serum is very expensive and can complicate experiments utilizing the cells. Many companies have developed "artificial serum" which enables cells to multiply without the use of serum. See data below. What are likely components of the artificial serum that enables cells to grow. Explain (limit 3-4sentences).
