Stem cells and poshaka dhatu:
In Ayurveda research field, the concept of rasayana with respect to dhatu and stem cells is initially introduced by Prasad BS .On the basis of stem cell type potency, this development is continued throughout life. It is found that the bone marrow contains at least two kinds of stem cells. One population, called hematopoietic stem cells, forms all types of blood cells in the body. A second small population called non-hematopoietic stem cell can generate bone, cartilage, fat and cells that support the formation of blood and fibrous connective tissue (skeletal stem cells). In some organs, such as the gut and bone marrow, stem cells regularly divide to repair and replace worn out or damaged tissues. In other organs, however, such as the pancreas and the heart, stem cells only divide under special conditions. Mesodermal progenitor cells are found throughout the body, they can differentiate to form multiple cell types (e.g. osteocytes, adipocytes, chondrocytes, fibroblasts, and smooth muscle cells) and they have a limited ability to self-renew. Rasa Dhatu may have all types of cell differentiate lineage responsible for the development of all saptadhatu, may be known as pluripotent. Recent studies suggest that the spermatogonial stem cells can be reprogrammed to become ES-like cells to acquire pluripotency. Wholesome shukradhatu may be considered as pluripotent, because it is responsible for the transmission of genetic information from an individual to the next generation. Thus, each dhatu carry the potency to regenerate further dhatu, because each avayava (organ) is formed by composition of many dhatus.
