  • Publication number: 20240117315
    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 cryopreserved 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: 20240050482
    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.

  • Publication number: 20220331485
    Abstract: A cryopreserved cartilage product is disclosed. The cryopreserved cartilage product can include a partially digested cryopreserved natural cartilage collagen matrix isolated from a subject. The collagen matrix can include viable cells embedded within the collagen matrix that are native to the collagen matrix and that were embedded in the collagen matrix when the collagen matrix was isolated from the subject, at least 70% of the embedded cells native to the collagen matrix can be viable in the cryopreserved cartilage product, and the partially digested collagen matrix can retain interaction between the collagen matrix and the native cells.
