The invention is directed to methods for treating nervous system injury and disease, in particular traumatic brain injury and degenerative nervous system disease. Such methods utilize novel compositions, including but not limited to trophic factor-secreting extraembryonic cells (herein referred to as TSE cells), including, but not limited to, amnion-derived multipotent progenitor cells (herein referred to as AMP cells) and conditioned media derived therefrom (herein referred to as amnion-derived cellular cytokine solution or ACCS), each alone or in combination with each other and/or other agents.

Compositions having a combination of specific biological components have been found to exert a number of useful effects in mammalian cells, including modulating TGF signaling, apoptosis, and proliferation of mammalian cells, as well as decreasing inflammation in mice. These components can be obtained commercially, or can be prepared from biological tissues such as placental tissues. Placental amniotic membrane (AM) preparations described herein include AM pieces, AM extracts, AM jelly, AM stroma, and mixtures of these compositions with additional components. The compositions can be used to treat various diseases, such as wound healing, inflammation and angiogenesis-related diseases.

An object of the present invention is to provide a cell composition for treatment of uterine tissue that heals damage occurring in uterine tissue, including intrauterine adhesion, to a state that enables pregnancy. In addition, an object of the present invention is to provide a method for producing this cell composition for treatment of uterine tissue, and a cell composition for treatment of uterine tissue produced according to that method. The cell composition, which has a first cell layer containing epithelial cells and a second cell layer containing stromal cells, and the first cell layer is laminated on the second cell layer, has the ability to heal damage occurring in uterine tissue, including intrauterine adhesion, and restore it to a state that enables pregnancy.

The present inventions in various aspects provide elastic biodegradable polymers. In various embodiments, the polymers are formed by the reaction of a multifunctional alcohol or ether and a difunctional or higher order acid to form a pre-polymer, which is cross-linked to form the elastic biodegradable polymer. In preferred embodiments, the cross-linking is performed by functionalization of one or more OR groups on the pre-polymer backbone with vinyl, followed by photopolymerization to form the elastic biodegradable polymer composition or material. Preferably, acrylate is used to add one or more vinyls to the backbone of the pre-polymer to form an acrylated pre-polymer. In various embodiments, acrylated pre-polymers are co-polymerized with one or more acrylated co-polymers.
