BACKGROUND Cardiac development is a complex process resulting in an integrated, multilineage tissue with developmental corruption in early embryogenesis leading to congenital heart disease. Interrogation of individual genes has provided the backbone for cardiac developmental biology, yet a comprehensive transcriptome derived from natural cardiogenesis is required to gauge innate developmental m...

Correct interactions with extracellular matrix are essential to human pluripotent stem cells (hPSC) to maintain their pluripotent self-renewal capacity during in vitro culture. hPSCs secrete laminin 511/521, one of the most important functional basement membrane components, and they can be maintained on human laminin 511 and 521 in defined culture conditions. However, large-scale production of ...

The breakthrough development of induced pluripotent stem cell (iPSC) technology is not only revolutionizing basic stem cell science but is also spurring efforts to reprogram one somatic cell type directly into another. Induced pluripotent stem cells provide scientists with a self-renewing and, thus, unlimited, source of pluripotent cells for targeted differentiation, in principle, into the enti...

Conventional culture systems are often limited in their ability to regulate the growth and differentiation of pluripotent stem cells. Microfluidic systems can overcome some of these limitations by providing defined growth conditions with user-controlled spatiotemporal cues. Microfluidic systems allow researchers to modulate pluripotent stem cell renewal and differentiation through biochemical a...

BACKGROUND Cardiomyocytes differentiated from human pluripotent stem cells can serve as an unexhausted source for a cellular cardiac disease model. Although small molecule-mediated cardiomyocyte differentiation methods have been established, the differentiation efficiency is relatively unsatisfactory in multiple lines due to line-to-line variation. Additionally, hurdles including line-specific ...

Herpesvirus saimiri (HVS) infects a range of human cell types with high efficiency. Upon infection, the viral genome can persist as high-copy-number, circular, nonintegrated episomes that segregate to progeny cells upon division. This allows HVS-based vectors to stably transduce a dividing cell population and provide sustained transgene expression in vitro and in vivo. Moreover, the HVS episome...

physiologically relevant cells from validated pathogen-free sources for applications such as cell replacement therapies, drug discovery, disease modelling and toxicology studies. The ground-breaking emerging field of induced pluripotent stem cells (iPS cells) in which somatic cells can be reprogrammed to a pluripotent stem cell state1 has further increased interest in stem cell technology. iPS ...

a common pathological process that occurred after brain injury is gliosis. gliosis involves the activation of glial cells to proliferate and become hypertrophic to occupy the injured brain areas. in order to form a defense system against the invasion of micro-organisms and cytotoxins into surrounding tissue, glial cells including astrocytes and microglia undergo reactive response to injury. neu...

The recent derivation of pluripotent stem cell lines from a number of different sources, including reprogrammed adult somatic cells, raises the issue of the developmental equivalence of these different pluripotent states. At least two different states representing the epiblast progenitors in the blastocyst and the pluripotent progenitors of the later gastrulating embryo have been recognized. Un...

Abstract This research is the first to produce induced pluripotent stem cell-derived inner ear sensory neurons in Neurog1 +/? heterozygote mouse using blastocyst complementation. Additionally, this approach corrected non-sensory deficits associated with heterozygosity, indicating that complementation specific endogenous function. work validates use of as a tool create novel insight into functio...
