  • Hydrogel particle encapsulated viable cells for in vivo regenerative treatment
    Patent number: 12582676
    Abstract: A composition for tendon and ligament regeneration includes a biologically compatible hydrogel suspension having spherical droplets. The spherical droplets have a diameter of about 100 ?m to about 300 ?m and a plurality of cells. The cells include marrow-derived mesenchymal stem cells (MSCs) with an average viability of about 90% or greater and cells that retain their stemness. A method for tendon and ligament regeneration includes forming the composition, purifying the composition, retrieving the composition, and administering the composition via injection into an injury site of injured tissue.
    Type: Grant

  • Hydrogel Particle Encapsulation and Suspension Media Removal
    Publication number: 20240026088
    Abstract: A hydrogel particle encapsulation and suspension media removal method includes combining hydrogel materials, which include a hydrogel polymer, a linker, a cargo suspension, and a suspension media. The hydrogel materials are mixed to form a hydrogel-suspension media mixture. The mixed hydrogel materials are polymerized to form hydrogel particles having encapsulated cargo. The suspension media is substantially removed from the hydrogel-suspension media mixture by: adding a density adjusting material, forming a three-phase solution that includes the density adjusting material settled between the hydrogel particles and the suspension media, centrifuging the three-phase solution, agitating the three-phase solution, centrifuging the three-phase solution, and retrieving the hydrogel particles lacking the suspension media.
