Co-culture experiments for the characterisation of early
embryo-maternal interaction and their disturbances after

In the first funding period we
established oviduct and endometrium cell culture system as
a basis for a systematic analysis of early embryo-maternal
communication. First hints of early embryo-maternal
interactions were found after transcriptome analysis of
co-cultured preimplantation bovine embryos (4-16 cell) and
oviduct cells. In addition protocols for the IVF of bovine
embryos were identified which causes epigenetic
disturbances. Furthermore these protocols resulted in
embryos with different developmental capacity.
Verification of candidate genes in the oviduct under
modified co-culture conditions.
Co-culture experiments with endometrium cells and ex
vivo embryos (morula or blastocyst stage) and subsequent
transcriptome and proteome analysis.
Comparative studies of co-cultured endometrium cells and
embryos originating from different IVF-protocols to
identify genes relevant for reduced pregnancy rates of
