  • Publication number: 20230363374
    Abstract: An improved packaging assembly for storing, distributing, treating, mixing, and dispensing tissue and/or cellular material and/or implantable material. The packaging assembly may include pouches, tubes, and a bag made of a sealable, flexible polymeric material that is open at one end and a needle-free swabable connector attached to the pouch at the other end and acting as a port to allow for the introduction or discharge of biological solutions, rinsing solution, and/or preservation solutions into the packaging assembly. The designed thickness of the wall of the packaging assembly facilitates efficient heat/cold transfer, which is useful for successful controlled rate freezing, quick thawing, and resuscitation of viable cells or tissue. The packaging assembly is also useful for combining additional biological fluids with the cellular material or tissue, and for efficient mixing of the biological fluids with the tissue and/or cellular material in the assembly.

  • Publication number: 20220184279
    Abstract: A method of preparing a decellularized placental membrane is provided. The method comprises removing cells from a pre-decellularized placental membrane comprising an amnion layer and a chorion layer to produce a decellularized placental membrane without separating the amnion layer from the chorion layer. The pre-decellularized placental membrane is obtained from an amniotic sac, and the decellularized placental membrane comprises the amnion layer and the chorion layer. Also provided is a decellularized placental membrane and a placenta-derived graft comprising the decellularized placental membrane. Further provided are the uses of the decellularized placental membrane or the placenta-derived graft.
