Human embryonic stem (ES) and embryonic germ (EG) cells derived from early embryos maintain pluripotency and can differentiate into various somatic cells. These findings impact biomedical research, though human ES cell control mechanisms require further study.

Area of Science:

  • Stem cell biology
  • Developmental biology
  • Regenerative medicine

Background:

  • Embryonic stem (ES) cells and embryonic germ (EG) cells are derived from early embryos.
  • These cells can be propagated indefinitely while maintaining pluripotency and the undifferentiated state.

Purpose of the Study:

  • To characterize candidate human ES and EG cell lines derived from blastocysts and gonads.
  • To compare the phenotype of human ES/EG cells with other stem cell types.

Main Methods:

  • Derivation of candidate ES and EG cell lines from human blastocysts and embryonic gonads.
  • Assessment of pluripotency and differentiation potential into multiple somatic cell types.
  • Phenotypic comparison with established cell lines (monkey ES, human embryonal carcinoma, mouse ES, human germ-cell-derived stem cells).

Main Results:

  • Candidate human ES and EG cell lines were established and demonstrated pluripotency.
  • These cells differentiated into multiple somatic cell types.
  • The phenotype of blastocyst-derived human ES cells closely resembled monkey ES cells and human embryonal carcinoma cells, but differed from mouse ES cells and human germ-cell-derived stem cells.

Conclusions:

  • Human ES and EG cell lines possess properties similar to other pluripotent stem cells.
  • Further research is needed to understand the control of growth and differentiation in human ES cells.
  • The development of these human cell lines holds significant promise for biomedical research.
