Establishment of mouse embryonic stem cell lines from somatic cell nuclei by nuclear transfer into aged, fertilization-failure mouse oocytes

It has been widely assumed that fresh oocytes are required for the establishment of embryonic stem cells (ES cells) via somatic cell nuclear transfer (SCNT). Such cell lines are referred to as ‘NT-ES cells’ [1]. This presumed requirement, however, gives rise to fundamental ethical concerns surrounding its potential application to human cells, as fresh oocytes must be obtained from a healthy fem...

Differentiation of Mouse Embryonic Stem Cell into Insulin-Secreting Cell

Purpose: Differentiation of mouse embryonic stem cells into Insulin secreting endocrine cells. Materials and Methods: In this study, Royan B1 mouse embryonic stem cell (derived from C57BL/6 mouse) were used. In directed differentiation method, embryonicstem cells after embryoid bodies formation were differentiated into insulin secreting cells. Nestin positive cells were obtained after culture ...

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 ...

The effect of BMP4 on mouse embryonic stem cell proliferation and differentiation into primordial germ cells

Background and Aim: Artificial gamete production from stem cells is a novel strategy for treatment of infertility. Among various stem cell sources, embryonic stem cells (ESC) can be considered as an appropriate source for in vitro formation of germ cells. In this study we evaluated the effect of BMP4 on proliferation and differentiation of mouse embryonic stem cells into primordial germ cells (...

Somatic and embryonic cell nucleus transfer into intact and enucleated immature mouse oocytes.

BACKGROUND The aim of our study was to evaluate the possibility of embryonic or somatic cell haploidization after fusion with intact or enucleated immature oocytes which were subsequently cultured in vitro. Embryonic or somatic cell nuclei do not undergo premature chromosome condensation when fused to intact or enucleated immature oocytes whose maturation is prevented by dibutyryl cyclic AMP (d...
