  • Patent number: 11738039
    Abstract: The present invention concerns polymer particles made from poly(lactic-co-glycolic acid) (PLGA) polymer, poly(lactic-co-glycolic acid)-polyethylene glycol-poly(lactic-co-glycolicacid) (PLGA-PEG-PLGA) copolymer, or the mixture of same, combined with hyaluronic acid molecules or hyaluronic acid salts, and the method for preparing same. The present invention also concerns injectable pharmaceutical or cosmetic compositions comprising such polymer particles, the method for preparing such compositions, and the use thereof for medical purposes, in particular for the prevention and/or treatment of musculoskeletal diseases, diseases and traumatic conditions of the skin, oral disorders, vaginal mucosa dryness and urinary infections or cystitis, dryness of the eye membrane and eye infections, obesity, and the use of same to combat ageing of the skin and/or for repairing the dermal tissue (mesotherapy).

  • Patent number: 10100276
    Abstract: The invention relates to a method for cell defrosting, comprising a step of defrosting a cell suspension consisting of a freezing medium and of cells, followed by a step of removing said freezing medium by filtration, said step of removing the freezing medium being carried out without the previous or simultaneous supply of medium. In particular, the filter is hydrophobic or, before addition of the cell suspension to be frozen, has been covered with a hydrophobic liquid forming a temporary barrier between the filter and the cell suspension. During defrosting, said hydrophobic liquid is removed by the application of a driving force which makes the liquid pass through the filter.
