ginger plant, zingiber officinale roscoe, is an important tropical plant used as spices and well known for its medicinal properties. it has a pungent and aromatic rhizome rich of zingiberen and gingerols. many secondary metabolites are known to accumulate in the plant cell culture systems. so, in this research, gingerols and zingiberene production of callus cultures were compared with regenerat...

abstract regeneration is a biological phenomenon, which takes place via two main mechanisms: first, dedifferentiation of mature cells followed by their differentiation into functional new cells and second, activation of endogenous somatic stem cells for regeneration of damaged or lost tissues. one of the best examples of healing process in mammals is the regeneration of damaged pinna in rabbits...

Cellular and tissue activities highly depend on environmental pH. Murine lung tissue, when cultured properly in-vitro, is a potent producer of hematopoietic growth factors. We have studied the effect of pH on the production of hematopoietic growth factors and protein synthesis by the murine lung in-vitro. Various concentrations of NaHC03 were used to adjust the pH of the culture medium unde...

the development of culture media able to mimic the preovulatory stage of follicular environment and support nuclear and cytoplasmic maturation of oocyte is important for in-vitro fertilization (ivf) programs. it seems that the best culture media for embryonic development and cell cleavage is the natural composition which surrounds the oocyte which has been used occasionally in human ivf program...
