An aqueous, non-immunogenic, injectable composition derived from human umbilical cords and methods of making thereof are described. The non-immunogenic composition is used for articular therapy in a human subject in need thereof. The non-immunogenic composition may include an aqueous human umbilical cord filtrate prepared without the use of exogenous enzymes resulting in exogenous enzymatic degradation/digestion.

The present invention provides a method for treating a human patient with a pathology by administering to the subject an effective amount of an agent selected from the group of: native full-length CCN3 proteins; analog CCN3 full-length proteins with native cysteine residues substituted by a replacement amino acid; CCNp native peptide fragments having from about 12 to about 20 amino acids; analog CCNp peptide fragments with native cysteine residues substituted with a replacement amino acid; and combinations thereof.

The invention discloses means of treating lung degenerative diseases including chronic obstructive pulmonary disease (CODP) using umbilical cord mesenchymal stem cells such as JadiCells alone, and/or using said cells under conditions that are activated in order to endow enhanced regenerative activity. In one embodiment said activation of said mesenchymal stem cells is performed through stimulation with a toll like receptor agonist at a concentration and duration sufficient to induce a >50% increase in keratinocyte growth factor expression from said stem cells. In another embodiment the invention provides the use of JadiCells as a means of producing exosomes, wherein said exosomes possess therapeutic properties capable of reducing inflammation, fibrosis and degeneration associated with COPD, as well as stimulation of regenerative activity. In some JadiCells are activated by a treatment with Activated Protein C.

Disclosed are means, compositions of matter and protocols useful for treatment of COVID-19 and/or other inflammatory pathologies through stimulation of T regulatory cells and/or T cells expressing CD73 using administration of umbilical cord derived mesenchymal stem cells such as JadiCells. In one embodiment dosage of JadiCells needed to treat a patient is determined by the increase of T regulatory cells and/or CD73 expressing cells that are increased in number and/or activity subsequent to a test dose of JadiCells. In another embodiment stimulators of T regulatory cells and/or CD73 expressing T cells are utilized together with JadiCells in order to augment therapeutic activity. In some embodiments administration of JadiCell is performed with low dose interleukin-2 as a treatment for COVID-19 or other inflammatory related pathologies.

A dental tissue regenerative composition. The composition includes a combination of (1) human dental pulp stem cells and (2) at least one of human umbilical vein endothelial cells or vascular endothelial growth factor. The combination is encapsulated in a light-activated gelatin methacrylate hydrogel.

The present invention provides a cell population and a method of obtaining the same. The cell population of the present invention is obtained by culturing mononuclear cells derived from bone marrow, umbilical cord blood, or peripheral blood in a medium containing serum and four or less of factors selected from the group consisting of stem cell factor, interleukin-6, FMS-like tyrosine kinase 3 ligand, thrombopoietin, and vascular endothelial growth factor.
