Combined Synergistic Effects of Aqueous Extracts of Parquetina nigrescens, Camellia sinensis and Telfaria occidentalis on Bone Marrow Haemopoietic Multipotent Stem Cells Proliferation in Irradiated Guinea Pigs

Cancer which is one of the most threatening human diseases is most commonly treated by chemotherapy and radiotherapy. However, these therapies are not tumor-specific. Normal tissues, particularly the bone marrow (BM), are extremely vulnerable to cytotoxicity caused by these therapies. How rapidly patients recover from these treatment modalities greatly depends on the percentage of resting stem cells remaining after such treatment. Antidotes are required for the untoward side effects of these therapies. As a means to protect stem cells or help damaged stem cells to recover, the use of biological response modifiers (BRMs) has received attention. The use of fruits or vegetables has the benefits of providing a cocktail of many different phytochemicals with multiple actions including antioxidant and anti-inflammatory effects. Certain whole-food extracts, such as blueberry, dietary fatty acids, particularly oleic acid and linoleic acid have been reported recently to actively promote the proliferation of haemopoietic stem cells [1]
