  • Publication number: 20200281981
    Abstract: Provided herein is a placental product comprising an immunocompatible amniotic membrane. Such placental products can be cryopreserved and contain viable therapeutic cells after thawing. The placental product of the present invention is useful in treating a patient with a tissue injury (e.g. wound or burn) by applying the placental product to the injury. Similar application is useful with ligament and tendon repair and for engraftment procedures such as bone engraftment.

  • Publication number: 20200231936
    Abstract: The present invention provides preparations of MSCs with important therapeutic potential. The MSC cells are non-primary cells with an antigen profile comprising less than about 1.25% CD45+ cells (or less than about 0.75% CD45+), at least about 95% CD105+ cells, and at least about 95% CD166+ cells. Optionally, MSCs of the present preparations are isogenic and can be expanded ex vivo and cryo-preserved and thawed, yet maintain a stable and uniform phenotype. Methods are taught here of expanding these MSCs to produce a clinical scale therapeutic preparations and medical uses thereof.

  • Publication number: 20200230176
    Abstract: This invention provides a fluid therapeutic placental product comprising placental cells and a placental dispersion comprising placental factors. The placental cells and the placental dispersion are derived from placental tissue. A placental tissue can optionally be an amnion, chorion, or a trophoblast-depleted chorion. The placental product of the present invention is useful in treating a patient with a tissue injury (e.g. wound or burn) by applying the placental product to the injury. Similar application is useful with ligament and tendon repair and for engraftment procedures such as bone engraftment.
