Large-Scale Identification of MicroRNA Targets in Murine Dgcr8-Deficient Embryonic Stem Cell Lines

Large-Scale Identification of MicroRNA Targets in Murine Dgcr8-Deficient Embryonic Stem Cell Lines

Small RNAs such as microRNAs play important roles in embryonic stem cell maintenance and differentiation. A broad range of microRNAs is expressed in embryonic stem cells while only a fraction of their targets have been identified. We have performed large-scale identification of embryonic stem cell microRNA targets using a murine embryonic stem cell line deficient in the expression of Dgcr8. The...

Large-Scale Expansion of Human Embryonic and Induced Pluripotent Stem Cells for Cell Therapy Applications

Successful isolation, derivation and culturing of human pluripotent stem cells, including human embryonic stem cells (hESCs) and human induced pluripotent stem (hiPSCs) cells in laboratory scale has opened new horizones for cell therapy applications such as tissue engineering and regenerative medicine. However, most of the cell therapy protocols using these unique cells require large number of ...

Microfabricated embryonic stem cell divider for large-scale propagation of human embryonic stem cells.

We have developed a novel method for fabricating an embryonic stem cell divider (ESCD) constructed from a poly(dimethylsiloxane) (PDMS) replica with a square or hexagonal pattern, and have proposed a new dissociation method for human embryonic stem cells (ESCs). An aspect ratio of the device as high as 2 was perfectly replicated in the cutting line. Using the ESCD, human ESC colonies can be eas...

Effects of Mouse Strain on Establishment of Embryonic Stem Cell Lines

Purpose: Embryonic stem (ES) cells are derived from the inner cell mass of blastocysts with self-renewal and pluripotency characteristics. These cells have potential for studies of in vitro differentiation, gene function, etc. This study was, therefore, initiated to establish new ES lines and evaluate the effects of strain on ES cell production. Materials and Methods: 3-5 day blastocysts were ...
