Vitalethine provides immune support in various cancer models and actually stabilizes mouse spenocytes (spleen cells) in culture. The spleen is an immune organ. Cells are normally grown in 10% serum, partly due to the fact that serum is so expensive to produce and maintain in a sterile and stable form. Restricting the vitalethine that is normally available to cells, however, can drastically affects performance of cells in culture, and indeed, their very stability in culture as illustrated by these studies. Cells on the left had vitalethine added and survived, while those on the right did not and tended to die off precipitously by a month. Many of the few remaining, without, shrivel up like fibroblasts. We survive if our immunity does.
