Cell Lines


ESI human embryonic stem cell (hESC) lines were derived under current Good Manufacturing Practice (cGMP) conditions on human fibroblast feeder layers and are available in research and clinical-grade formats. As the first clinical-grade hESC lines, ESI cell lines are among the best-characterized and documented available today, with complete genome sequence, STR-fingerprint and HLA-type data available.

Manufactured in compliance with quality systems
ESI cell lines are backed with donor history and testing information in best compliance with current Good Tissue Practice (cGTP) and conform to Global Ethical Standards and Clinical Cell Regulations.

  • Complete genomic profile and comprehensive data available for purchase
  • Approved by NIH and available on NIH Stem Cell Registry
  • Available for funding under CIRM Partnership
