A Review on Micropropagation of Rare Plant Species: Ashwagandha
Abstract: Micropropagation is a technique of rapidly multiplying stock plant materials to large number of progeny plants. Some plant species available in the nature contains few traits of medicinal value. From those species, Withania somnifera is found to be rarely available, having medicinal value and also well in vitro regeneration. Most of the plant species especially like Withania somnifera are having medicinal values and cultivated on land even after their good …

The Interaction of Extracellular Matrix and Growth Factors
Abstract: The extracellular matrix (ECM) regulates cell behavior by influencing cell proliferation, survival, shape, migration and differentiation. ECM assembly is regulated by the 3D environment and the cellular tension that is transmitted through integrins. The hematopoietic microenvironment is a complex structure in which stem cells, progenitor cells, stromal cells, growth factors, and ECM molecules each interact to direct the coordinated regulation of blood cell development. Hematopoietic growth factors are any of …
