Provided herein is a placental product comprising an immunocompatible chorionic membrane. Such placental products can be cryopreserved and contain viable therapeutic cells after thawing. 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.

The invention discloses a method for inhibiting the growth of cancer cells by use of an anti-cancer composition containing a conditioned cell culture medium from mesenchymal stem cells and cytokines. It comprises the steps of applying a composition with a conditioned cell culture medium from stem cells and at least one cytokine to cancer cells for growth inhibition of the cancer cells. The cell culture medium can be conditioned with Wharton's Jelly mesenchymal stem cells (WJMSCs) as an WJMSCs-conditoned cell culture medium, and the at least one cytokine is selected from a group consisting of bone morphogenetic protein-4, Dickkopf-related protein, Interferon-β and tumor necrosis factor-related apoptosis-inducing ligand.

The present disclosure relates to a method of generating bioartificial reptile leather by in vitro culturing of isolated cells the chorioallantois of hatched reptile eggs. The disclosure allows production of reptile leather without the ethical issues of conventional reptile farming and the trapping and killing of reptiles for their skin. Furthermore the disclosure allows production of reptile leather from species that are not abundantly available as skin products, such as from endangered species.

The present invention relates to stem cells derived from villi adjacent to the chorionic plate (VCP), and a cell therapeutic agent comprising same. Stem cells derived from the tissue of VCP comprising, of the total villi, the region that is ⅓ of the distance from the area adjacent to the chorionic plate up to the villus distal part, and the basal region of the villi, according to the present invention, exhibit uniform growth characteristics, and proliferation characteristics superior to those of stem cells derived from other placental tissue, and exhibit remarkably excellent differentiation into cartilage, bone and fat, thereby being effectively usable in various tissue regeneration treatments requiring the regeneration of cartilage, bone and fat, and, particularly, in cartilage regeneration and osteoarthritis treatment.

Compositions comprising unseparated amnion/chorion derived from the placenta and methods of preparing and using those compositions are provided. Washing or preservation of placental tissue according to the methods of the disclosure may allow for one or more benefits such as more efficient removal of blood remnants, retention of wound healing and tissue regeneration components, better handling characteristics, increased absorption potential, or improved healing capacity. The present invention also includes methods of healing a wound of the skin, eye, nerve, tendon, or dura comprising applying the compositions of the invention to the wound.

[Problem] To provide a supporting bath useful for three-dimensional tissue culture and a method for producing cultured three-dimensional tissue by using the supporting bath. [Solution] Use of a supporting bath for three-dimensional tissue culture, that comprises polymer and water, wherein a thixotropic gel is formed in the bath with the gel being dissolvable in solvent. Also, use of a method for producing the supporting bath.

The present invention relates to a method for producing a composition which comprises animal protein, comprising (a) isolating precursor cells from perinatal tissue of a mammal; (b) incubating the precursor cells under conditions which lead to a myogenic differentiation of the precursor cells; and (c) harvesting the cells. The present invention also relates to a method for producing precursor cells from perinatal tissue, to animal protein produced according to the invention, and precursor cells produced according to the invention. The present invention further relates to the use of a culture medium which has a reduced content of methionine in comparison to standard medium, to the differentiation of precursor cells, and to a method for the in vitro production of a meat-like composition.

Described herein are compositions and methods of treating a cardiac condition using modified placental tissue or an extract of a placental tissue, capable of recruiting stem cells or promoting healing in vivo and in vitro.

The present invention discloses a use of a mitochondrial extract to treat and/or prevent a kidney injury-related disease. Specifically, by administering the mitochondrial extract disclosed in the present invention to a patient having a kidney injury-related disease, the kidney injury-related disease can be effectively alleviated and prevented from deterioration.

Disclosed herein are mortal pluripotent stem cells produced in vitro and compositions thereof. Disclosed herein are methods of treating a disorder or condition by utilizing the cells disclosed herein. Also disclosed herein are methods of growing cells in culture medium as well as populations of mortal pluripotent stem cells differentiated therefrom.
