  • Patent number: 9012415
    Abstract: This invention refers to photo-crosslinked hydrogel materials based in gellan gum suitable for tissue engineering and regenerative medicine applications or as drug delivery systems. Formulations of gellan gum with different degrees of acylation serve as precursor material for insertion of a polymerizable moiety. The materials are capable of free radical polymerization with a photo-initiator at mild temperatures and exposure to ultraviolet light, enabling control of reticulation and withstanding the encapsulation of human and animal cells and/or drugs, and any combination thereof. The physicochemical and biological properties can be adjusted by combining different formulations of gellan gum and reaction conditions.

  • Publication number: 20100273253
    Abstract: The present invention refers to the conception process of new dynamic systems for cell culture in 3D supports appropriate to its growing. These are constituted by:—cylindrical container (1) exhibiting a terminal area with a truncated inverted cone shape (2) in the lower internal zone;—cylindrical screw lid (4) the upper external zone of which has a cylindrical tube (7) that penetrates the whole extension of the lid, also containing a coupling central hole (6);—screw cap (10) containing a filter (11) that fits in the cylindrical tube (7) of the lid (4); hexagonal shaft (12) with an insertion for the derivations in the lower terminal part (part ‘E’);—Derivation in the form of tweezers forming a gripping tool that sustains the 3D supports. These new systems allow a yield increase in biological material costs, laboratory consumable and time spent by technical specialized staff.
