Abstract: The invention relates to a method for analyzing fetal nucleic acids from the supernatant of the culture medium of fetal cell cultures of an in vitro fertilization, comprising the steps: a) removing from the culture vessel used for cultivating the fertilized egg cell the cell-free supernatant of the in vitro fertilization culture medium, which supernatant contains fetal nucleic acid, b) enriching the fetal nucleic acids contained in the supernatant, and c) carrying out an analysis of the nucleic acids present in the cell-free supernatant.

Abstract: Use of an immunomodulatory, immunostimulatory, or immunosuppressive drug in the manufacture of a medicament for treatment of a skin related disease or disorder, wherein the drug is formulated for topical administration to porated skin having a plurality of pores with predetermined geometry such that the concentration of the drug in combination with the predetermined geometry of the pores are effective in treatment of the skin related disease or disorder.

Abstract: A method for producing cell lines or individual organs, differentiable donor cells being supplied to a morula or blastocyst which is cultivated under conditions that ensure a further development of the morula or blastocyst in stages in which newly formed cell lines having a higher degree of differentiation occur, as well as isolation of the cell lines or further differentiation of the cell lines into organs. The method according to the present invention is distinguished in that the cells of the morula or the internal cell mass of the blastocyst have a restricted survivability in comparison to the particular wild type or their survivability is reduced through suitable cultivation conditions, and the donor cells supplied to the morula or blastocyst have varying degrees of differentiation. A significantly shortened cultivation period of the donor cells may thus be achieved in comparison to typical methods, through which the provision of natural stem cells is favored, and perhaps made possible for the first time.
