    biological dogma. Telomerase activity is down regulated as a cell specializes from stem cell to progenitor to terminal differentiation. This research was sparked by prior evidence that correlated telomerase with cellular differentiation and apoptosis and even telomeric additions to chromosomal breaks. Furthermore, the critical reason for completing this study was for the understanding of cellular growth and these implications in cancer. The choice of murine embryonic stem cells was determined because of higher

    The first neural induction in amphibian embryos has given the Nobel Prize in Medicine award to Hans Spemann in 1935 for his “Spemann-Mangold organizer” paper. The discovery with her student Hilde Mangold leads to establishment of a neuroectodermal primordium from where the nervous system arise involving induction of chemicals such as the fibroblast growth factor (FGF) and WNT signalling, together with inhibition of bone morphogenetic protein-4 (BMP) signalling activity to promotes neuron development

    Over the past decade, stem cell biology has been an area that has caused much controversy. Stem cells have the ability to differentiate into many different types of cells and therefore, advocates of stem cell research argue that the cells have various medical applications. On the other hand, opponents of stem cell research denounce the use of human embryos for research purposes, claiming that the embryos represent human lives and that experimentation with them and subsequent annihilation of them

    organ development from specific progenitor cells is tightly controlled by the surrounding biochemical environment. Specifically, oxygen tension, otherwise known as the partial pressure of oxygen, is one of many critical factors playing into the differentiation process of cells into specific tissues. There is a delicate balance between hypoxia (a result of low oxygen tension) and normoxia through the cell life cycle, and this balance varies depending on the biological micro niche in which it resides

    identification and functionality of molecular components as part of development. Fibroblast growth factor (FGF) signaling plays an important role in the regulatory network present in embryonic pulmonary development. FGF controls cell proliferation, differentiation and pattern formation; however, the interaction of FGF with other signaling pathways is still questioned by researchers. FGF-7 and FGF-10 are important for patterning and growth of the lung bud and are differentially regulated by FGF-1 and FGF-2

    REGENERATIVE THERAPY Regeneration is the process of renewal or restoration of a body, bodily part, or biological system after injury or as a normal process. [1] It is the process that makes genomes, cells, organisms flexible to natural changes that cause disturbance or damage. Every species is capable of regeneration, from bacteria to humans. Regeneration can be of two types- it can either be complete where the new tissue is the same as the lost tissue, or incomplete where the necrotic tissue comes
