Recent breakthrough studies documented consistent activation of specific endogenous retroviruses in human embryonic stem cells and preimplantation human embryos and demonstrated the essential role of the sustained retroviral activities for maintenance of pluripotency and embryonic stem cell identity. Present analysis has led to the hypothesis that activation of the human stem cell-associated re...

Despite exhaustive studies, molecular mechanisms governing blastocyst formation, implantation to the uterine endometrium and placentation have not been definitively characterized. GATA family proteins are a group of zinc finger transcription factors, for which gene ablations eventually result in embryonic death later in pregnancy. These findings suggested that GATA factors are not essential for...

Neurodegenerative diseases are the hereditary and sporadic diseases which are characterized by progressive neuronal loss of the nervous system and are emerging as the leading cause of death, disabilities, and a socioeconomic burden due to an increase in life expectancy. There are many neurodegenerative diseases including Alzheimer’s disease, Parkinson’s, disease, amyotrophic lateral...

Cell-gene therapy is a dynamic constituent of novel medical biotechnology. Neurodegenerative disordersin which damage to or demise of specific brain cell types plays central role, are clear examples of diseasecandidate for cell replacement therapy. Dopaminergic (DAergic) neurons biosynthesize dopamine, a vitalneurotransmitter in the central nervous system. Due to the involveme...
