Abstract:
PROBLEM TO BE SOLVED: To provide pharmaceutical compositions to treat an individual having cancers including multiple myeloma, bone cancer, neuroblastoma, osteosarcoma, Ewing's sarcoma, chondrosarcoma, chordoma, malignant fibrous histiocytoma of bone, fibrosarcoma of bone or the like.SOLUTION: A pharmaceutical composition contains an adherent placental stem cell that have been isolated from human placental tissue, the stem cell being CD105+, CD200+, CD10+, and CD34-, wherein the stem cell exists in a sufficient amount to treat a cancer.
Abstract:
PROBLEM TO BE SOLVED: To provide isolated placental stem cells, populations of placental stem cells, compositions comprising the stem cells, and methods for obtaining the stem cells.SOLUTION: The invention provides isolated stem cells, and cell populations comprising such stem cells, wherein the stem cells are isolatable from placental tissue (e.g., amnion, chorion, placental lobe, etc.). The placental stem cells exhibit one or more characteristics of a stem cell (e.g., exhibit markers associated with stem cells, replicate at least 10-20 times in culture state in an undifferentiated state, differentiate into adult cells representative of the three germ layers, etc.), and can adhere to a tissue culture substrate (e.g., tissue culture plastic such as the surface of a tissue culture dish or multiwell plate).
Abstract:
PROBLEM TO BE SOLVED: To provide methods of immunomodulation using placental stem cells and placental stem cell populations.SOLUTION: The placental stem cells: express CD200 and HLA-G; express CD73, CD105, and CD200; express CD200 and OCT-4; express CD73, CD105, and HLA-G; express CD73 and CD105 and facilitate the formation of one or more embryoid-like bodies in a population of placental cells that comprises the plurality of placental stem cells when the population is cultured under conditions that allow formation of embryoid-like bodies; and/or express OCT-4 and facilitate the formation of one or more embryoid-like bodies in a population of placental cells that comprises the plurality of placental stem cells, when the population is cultured under conditions that allow formation of embryoid-like bodies.
Abstract:
PROBLEM TO BE SOLVED: To provide a method for preparing a collagen biofabric from a placental membrane (preferably human placental membrane) having a chorionic and amniotic membrane, by decellularizing the amniotic membrane. SOLUTION: There is provided a method for preparing a collagen biofabric from a placental membrane having a chorionic and amniotic membrane, wherein the method comprises (a) a step for isolating the amniotic membrane from the chorionic membrane; and (b) a step for decellularizing the amniotic membrane not to contact the amniotic membrane to the enzyme. The collagen biofabric has numerous utilities in the medical and surgical field including for example, blood vessel repair, construction and replacement of a blood vessel, tendon and ligament replacement, wound-dressing, surgical grafts, ophthalmic uses, sutures, and others.

Abstract:
PROBLEM TO BE SOLVED: To provide collagenous membranes produced from amnion, and to provide a method for preparing a three-dimensional scaffold for forming a surgical graft.SOLUTION: A collagen biofabric of the invention has the structural integrity of the native non-treated amniotic membrane, i.e., the native tertiary and quaternary structure. The present invention provides a method for preparing the collagen biofabric from a placental membrane, preferably a human placental membrane, having a chorionic and amniotic membrane, by decellularizing the amniotic membrane. In a preferred embodiment, the amniotic membrane is completely decellularized. The collagen biofabric of the invention has numerous utilities in the medical and surgical field including for example, blood vessel repair, construction and replacement of a blood vessel, tendon and ligament replacement, wound-dressing, surgical grafts, ophthalmic uses, sutures and the like. The benefits of the biofabric are, in part, due to its physical properties such as biomechanical strength, flexibility, suturability, and low immunogenicity, particularly when derived from human placenta.
Abstract:
PROBLEM TO BE SOLVED: To provide a method for extracting and recovering embryonic-like stem cells, such as pluripotent or multipotent stem cells, from an exsanguinated human placenta.SOLUTION: A placenta is treated to remove residual umbilical cord blood by perfusing an exsanguinated placenta, preferably with an anticoagulant solution, to flush out residual cells. The residual cells and perfusion liquid from the exsanguinated placenta are collected, and the embryonic-like stem cells are separated from the residual cells and perfusion liquid. The invention also provides a method for utilizing the isolated and perfused placenta as a bioreactor to propagate endogenous cells, including, but not limited to, embryonic-like stem cells. The invention also provides methods for propagating endogenous cells in a placental bioreactor and collecting the propagated endogenous cells and bioactive molecules therefrom.
Abstract:
PROBLEM TO BE SOLVED: To provide improved cytotherapeutic formulations regarding the improvement of therapeutics utilizing cytotherapeutic formulations, a method for producing them, unit dosage forms of such agents and new paradigms administering cytotherapeutic units to patients in need of therapy.SOLUTION: The present invention provides cytotherapeutic units comprising predetermined numbers of selected types of cells having differentiation potency. Assurance of the nature and identities of such cells is achieved through assay and certification of the numbers and identities. Therapeutic modalities are provided. Libraries of cell preparations with assayed and preferably certified populations are preferred and the preparation of cell preparations tailored to specific patients or disease states are provided.
Abstract:
PROBLEM TO BE SOLVED: To provide a composition and a method for using embryonic-like stem cells that originate from a post-partum placenta with cord blood compositions or other stem or progenitor cells. SOLUTION: The embryonic-like stem cells can be used alone or in a mixture with other stem cell populations. The embryonic-like stem cells may be mixed with other stem cell populations including umbilical cord blood, fetal and neonatal hematopoietic stem cells and progenitor cells, human stem cells and progenitor cells derived from bone marrow. The embryonic-like stem cells and the mixed populations of embryonic-like stem cells and stem cells have a multitude of uses and applications, including e.g. therapeutic uses for transplantation and treatment and prevention of disease, and diagnostic and research uses.
