Process for extracting and purifying the recombinant Placental Growth Factor (PLGF) expressed in inducible prokaryotic expression systems comprising the following steps: I) fermentation of the bacterial cells, II) extraction and purification of the inclusion bodies, III) renaturation of the expressed protein, IV) ion-exchange chromatography, V) reverse-phase chromatography.

Production process of recombinant placental growth factor

The invention relates to the preparation of placental growth factor (PLGF)-comprising therapeutic and cosmetic compositions capable of increasing angiogenesis of the cutaneous, subcutaneous and internal organ connective tissue. Such compositions are suitable for the treatment of pathological or natural states benefiting from the formation or regeneration of new vessels of the cutaneous compartment, such as scleroderma, its various manifestations, skin aging or loss of hair.
