  • Title: [Production of hematopoietic cells from ES cells].
    Author: Sainteny F.
    Journal: J Soc Biol; 2001; 195(1):13-8. PubMed ID: 11530494.
    Abstract:
    Murine embryonic stem (ES) cells are cell lines established from blastocyst which can contribute to all adult tissues, including the germ-cell lineage, after reincorporation into the normal embryo. ES cell pluripotentiality is preserved in culture in the presence of LIF. LIF withdrawal induces ES cell differentiation to nervous, myocardial, endothelial and hematopoietic tissues. The model of murine ES cell hematopoietic differentiation is of major interest because ES cells are non transformed cell lines and the consequences of genomic manipulations of these cells are directly measurable on a hierarchy of synchronized in vitro ES cell-derived hematopoietic cell populations. These include the putative hemangioblast (which represents the emergence of both hematopoietic and endothelial tissues during development), myeloid progenitors and mature stages of myeloid lineages. Human ES cell lines have been recently derived from human blastocyst in the USA. Their manipulation in vitro should be authorized in France in a near future with the possibility of developing a model of human hematopoietic differentiation. This allows to envisage in the future the use of ES cells as a source of human hematopoietic cells.
