The regulative capability of single cells to give rise to all primary embryonic lineages is termed pluripotency. Observations of fluctuating gene expression and phenotypic heterogeneity in vitro have fostered a conception of pluripotency as an intrinsically metastable and precarious state. However, in the embryo and in defined culture environments the properties of pluripotent cells change in a...
Abstract Plant cells cultivated in vitro are a convenient model for studying the genetic and physiological mechanisms necessary to acquire state of pluripotency. Earlier studies on plant Arabidopsis thaliana (L.) Heynh. have identified key role genes that determine pluripotency shoot apical meristem de novo regeneration tissue culture. In accordance with this, mutant plants higher level express...
Maintenance of pluripotency is crucial to the mammalian embryo's ability to generate the extra-embryonic and embryonic tissues that are needed for intrauterine survival and foetal development. The recent establishment of embryonic stem cells from human blastocysts (hESCs) provides an opportunity to identify the factors supporting pluripotency at early stages of human development. Using this in ...
OBJECTIVES The importance of Oct4 and Sox2 in maintaining pluripotency and self-renewal is well-understood, but the functions of Klf4 and c-Myc has not been fully investigated. In the present study, we attempted to determine the roles of Klf4 and c-Myc on pluripotency maintenance of porcine induced pluripotent stem (piPS) cells. MATERIALS AND METHODS In this experimental study, we performed s...
