The effects of initial osmotic pressure (IOP) on the production of ginseng polysaeeharide and ginseng saponin were studied in suspension cultures of Panax notoginseng cells. At higher IOP, the specific saponin production and intraceUular carbohydrate storage were increased, while the plant cell volu

β¦ Synopsis
Cell cultures of Panax ginseng and Catharanthus roseus producing secondary metabolites were preserved in liquid nitrogen or under mineral oil for six months. The growth behaviour and the ability of the cultures to produce ginsenosides or indole alkaloids were measured after a recovery period and compared with cultures maintained by frequent subcultivation during the same period. Neither growth kinetics nor the degree of vacuolization during growth were affected by the long term preservation. Some changes in secondary metabolism were however found, indicating that preservation under mineral oil does not preserve the productivity of cell cultures whereas the cryogenic method does.

The stromal cell layer is believed to play an important role in long-term human bone marrow cultures (LTHBMCs). At present, neither the role that the stromal cell extra-cellular matrix (ECM) plays in influencing stroma behavior is well understood nor are the effects of stroma aging. Rapid medium exc
