Abstract
The present study was conducted to establish haploid embryonic stem (ES) cell lines using fluorescent marker-carrying rats. In the first series, 7 ES cell lines were established from 26 androgenetic
haploid blastocysts. However, only 1 ES cell line (ahES-2) was found to contain haploid cells (1n = 20 + X) by fluorescence-activated cell sorting (FACS) and karyotypic analyses. No chimeras were detected among the 10
fetuses and 41 offspring derived from blastocyst injection with the FACS-purified haploid cells. In the second series, 2 ES cell lines containing haploid cells (13% in phES-1 and 1% in phES-2) were established from 2
parthenogenetic haploid blastocysts. Only the phES-2 cell population was purified by repeated FACS to obtain 33% haploid cells. Following blastocyst injection with the FACS-purified haploid cells, no chimera was observed
among the 11 fetuses; however, 1 chimeric male was found among the 47 offspring. Although haploid rat ES cell lines can be established from both blastocyst sources, FACS purification may be necessary for maintenance and
chimera production.

Abstract
Normal mouse pluripotent stem cells were originally derived from the inner cell mass (ICM) of blastocysts and shown to be the in vitro equivalent of those pre-implantation embryonic cells, and thus were called embryonic stem cells (ESCs). More than a decade later, pluripotent cells were isolated from the ICM of human blastocysts. Despite being called human ESCs, these cells differ significantly from mouse ESCs, including different morphology and mechanisms of control of pluripotency, suggesting distinct embryonic origins of ESCs from the two species. Subsequently, mouse pluripotent stem cells were established from the ICM-derived epiblast of post-implantation embryos. These mouse epiblast stem cells (EpiSCs) are morphological and epigenetically more similar to human ESCs. This raised the question of whether cells from the human ICM are in a more advanced differentiation stage than their murine counterpart, or whether the available culture conditions were not adequate to maintain those human cells in their in vivo state, leading to a transition into EpiSC-like cells in vitro. More recently, novel culture conditions allowed the conversion of human ESCs into mouse ESC-like cells called naïve (or ground state) human ESCs, and the derivation of naïve human ESCs from blastocysts. Here we will review the characteristics of each type of pluripotent stem cells, how (and whether) these relate to different stages of embryonic development, and discuss the potential implications of naïve human ESCs in research and therapy.

Abstract
This study was designed to investigate whether supplementation of 2i medium with leukemia inhibitory factor (LIF) and/or forskolin would support establishment of germline-competent rat embryonic stem (ES) cell lines. Due to the higher likelihood of outgrowth rates, supplementation of forskolin with or without LIF contributed to the higher establishment efficiency of ES cell lines in the WDB strain. Germline transmission competency of the chimeric rats was not influenced by the profile of ES cell lines until their establishment. When the LIF/forskolin-supplemented 2i medium was used, the rat strain used as the blastocyst donor, such as the WI strain, was a possible factor negatively influencing the establishment efficiency of ES cell lines. Once ES cell lines were established, all lines were found to be germline-competent by a progeny test in chimeric rats. In conclusion, both LIF and forskolin are not essential but can play a beneficial role in the establishment of "genuine" rat ES cell lines.
