This invention generally relates to methods to differentiate pluripotent stem cells, such as embryonic stem, embryonic germ, or embryo-derived cells, to obtain subpopulations of cells from heterogeneous mixtures of cells wherein the subpopulation of cells possess reduced differentiation potential compared to the original pluripotent stem cells and where the subpopulation is capable of being propagated.

Disclosed are compositions and methods for reducing the severity of a birth defect in a mammal by exposing the mammal (e.g., in utero) to a herpes virus amplicon particle comprising a cis element-flanked transgene and a sequence encoding a transposase. Upon expression, the transposase inserts the transgene into the genome of a cell (e.g., a neuron) within the mammal and the transgene expresses a polypeptide or RNA that compensates for a protein or gene defect that is causally associated with the birth defect.

Aspects of the present invention relate to methods to differentiate pluripotent primordial stem cells, such as human embryonic stem (“hES”) cells, human embryonic germ (“hEG”) cells, human embryo-derived (“hED”) cells and human embryonal carcinoma (“hEC”) cells, to obtain subpopulations of cells from heterogeneous mixtures of cells, wherein the subpopulation of cells possess reduced differentiation potential compared to the original pluripotent stem cells and where the subpopulation is capable of being propagated 20 or more population doublings. This invention also provides novel compositions of such subpopulations of cells and methods to propagate and differentiate said cells.

[FR] L'invention concerne des compositions et des procédés de réduction de la gravité d'une anomalie à la naissance chez un mammifère consistant à exposer le mammifère (par exemple in utéro) à une particule d'amplicon de virus herpétique contenant un transgène flanqué d'un élément cis et une séquence codant une transposase. Lors de l'expression, la transposase insère le transgène dans le génome d'une cellule (par exemple un neurone) à l'intérieur du mammifère et le transgène exprime un polypeptide ou un ARN qui compense une anomalie protéique ou génique associée par effet de causalité à l'anomalie à la naissance.
