The purpose of this study is

  1. To generate human embryonic stem cells lines (hESC) lines
  2. Study of the factors that contribute to differentiation towards germ cell.

Normal Healthy Embryos

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Basic Research. Unveiling Factors That Contribute to Germ Cell Differentiation

Further study details as provided by Soroka University Medical Center:

Primary Outcome Measures:
  • New hESC [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    Donated embryos will be used for derivation of the Es cells

Secondary Outcome Measures:
  • Factors that contribute to germ cells differentiation [ Time Frame: 4 years ] [ Designated as safety issue: No ]
    We shall employ the knowledge from a study of sperm differentiation in mice to instruct the differentiation of ES cells towards germ cells
