    Abstract: The present invention is directed to hematopoietic progenitor cells isolated from a tissue specimen, such as marrow cells or peripheral blood, and to the method of co-culturing isolated hematopoietic progenitor cells with human mesenchymal stem cells to induce megakaryocyte differentiation and platelet production. In addition, hematopoietic stem cells can be genetically engineered to carry genes of interest particularly for the expression of physiologically active proteins. In the presence of mesenchymal stem cells, the transduced cells carry the new genetic material and express gene products that can be used to modulate blood disorders.

    Abstract: Disclosed are compositions comprising umbilical tissue, wherein the umbilical tissue comprises one or more engineered channels. Also disclosed are compositions comprising a previously cryopreserved umbilical tissue, wherein after cryopreservation and subsequent thawing the umbilical tissue comprises: a) viable cells native to the umbilical tissue; b) tissue integrity of native umbilical tissue; c) one or more growth factors that are native to the umbilical tissue; and d) depleted amounts of one or more types of functional immunogenic cells. Disclosed are methods of producing compositions comprising umbilical tissue, wherein the umbilical tissue comprises one or more engineered channels. Also disclosed are methods of treating damaged tissue comprising administering to the site of the damaged tissue compositions comprising umbilical tissue, wherein the umbilical tissue comprises one or more engineered channels.
