Preparation and method for producing a preparation comprising mesenchymal stem cells

A method of producing a preparation or a tissue derivative comprising mesenchymal stem cells, to be used in cellular therapy, for cosmetic treatments, for replacing a tissue or an organ, or inducing or accelerating tissue repair or regeneration, the method comprising the following steps:

• extracting tissue containing mesenchymal stem cells from a cadaveric donor by liposuction process or by surgical removal of parts of said tissue;
• and
• mechanically treating said tissue,
• wherein said mechanically treated tissue includes a fluid component comprising one or more of an oily component, a blood component, or a sterile solution, and a solid component comprising cell fragments, cells and one or more cell macro-agglomerates of heterogeneous sizes, and
• wherein the steps of mechanically treating separates and removes the fluid component from the solid component, whereby an emulsion of fluid components is generated by mechanical stirring.
