Process for promoting differentiation of cells, protein substances having lipid transfer activity, compositions containing them, DNA sequences and corresponding oligonucleotide probes.

摘要

The present invention relates to a method for promoting the differentiation of cells in culture, in particular with a view to tissue differentiation, embryogenesis, and / or organogenesis, characterized in that it is introduced into the medium of culture in concentration effective to obtain the differentiation of cells, at least one lipid transfer protein or "LTP" or LTP analogue. BR/ It also relates to a plant obtained by such a method, protein substances and proteins having a lipid transfer activity and a composition comprising at least one such substance. Finally, it relates to a DNA sequence coding for an LTP and a probe whose sequence is deduced from the sequence of said protein. / P
