Protokollerne beskriver to in vitro udviklingsmæssige toksicitet testsystemer (UKK og UKN1) baseret på humane embryonale stamceller og transkriptom studier. Testsystemet forudser human udviklingsmæssige fare toksicitet, og kan bidrage til at reducere dyreforsøg, omkostninger og den tid, der kræves til kemisk sikkerhed test.
