Abstract
The invention relates to novel hydrated lamellar phases or liposomes which contain either polyethylenimine, or a substance which stimulates intracellular penetration selected from the group consisting of:
- i) a fatty monoamine of carbon-containing chain length of between C10 and C18;ii) a cationic polymer,optionally at least one fluorescent compound which is essentially inert with respect to the intracellular penetration, which enables this penetration to be visualised.
