Abstract: The present invention features colony-forming unit cells derived from the chorion of human placenta and describes compositions and methods for the uses of chorionic cells and their products for therapeutic purposes based upon production and release of multiple growth factors and cytokines by these cells stimulating tissue regeneration independent of engraftment, as well as differentiation into a specific cell type.

Abstract: The subject matter of this invention is a novel method to augment the process of obtaining populations of placental hematopoietic stem and progenitor cells for use in medical practices. A method of augmentation of stem cells collection from placenta is claimed comprising the steps of (a) infusing placental vessels cell preservation compound and a with a composition containing blockers of cell adhesion receptors, (b) incubating said placenta for a sufficient period of time, (c) placing placenta in a containment with sufficient intensity of electromagnetic or ultrasound field for a sufficient period of time; (d) eluting cell suspension from placental vessels, (e) collecting cell suspension and harvesting cells. Invention further claims a method of treatment a disease by means of administering therapeutic composition containing said placental-derived hematopoietic stem cells.

Abstract: The present invention provides methods of cryopreserving stem and progenitor cells in a mammalian placenta; and methods of obtaining fetal stem and progenitor cells from a cryopreserved mammalian placenta. Cells obtained by carrying out the methods can be used in a variety of therapeutic applications.

Abstract: An apparatus and method are described for capillary separation of macromolecules and precise post-separation blotting. Apparatus include disposable separating element (capillary), which contains a sieving or interaction matrix inside, an external layer of blotting material, positioned close to the boundary of said sieving or interaction matrix, and the membrane with changeable permeability for separated material; said membrane separates blotting layer from the sieving or interaction matrix. After separation of macromolecules in capillary with initially non-permeable walls, chemical or physical modification of the membrane is performed, which is followed by changing the vector of driving forces for transfer, so that separated molecules are moved through the walls of the capillary and blotted to the outer layer of separating element, which contains blotting material. Means of modification of the membrane include chemical or physical modification, leading to changes in permeability.
