Abstract
Compositions for use in treatment of a variety of tissue diseases include stem cells and stem cell released molecules (SRM's) suspended in an aqueous solution with a cellulosic material or other thickening agent. The stem cells and SRM's can be derived from one or more distinct cell lines. The SRM's can further include one or more mucins, cytokines, or growth factors. Exemplary formulations include stem cells and SRMs derived from epithelial stem cells, corneal limbal stem cells, and fibroblasts. Other compositions and methods for formulation thereof are described.

A method for forming a therapeutic composition, comprising:
- providing an amount of first stem cells;
- culturing said first stem cells in vitro such that said first stem cells secrete one or more first stem cell released molecules;
- providing an amount of second stem cells, said second stem cells being distinct from said first stem cells;
- culturing said second stem cells in vitro such that said second stem cells secrete one or more second stem cell released molecules;
- combining said first and second stem cells and stem cell released molecules;
- introducing a thickening agent;
- and
- suspending said first and second stem cells, first and second stem cell released molecules, and thickening agent in an aqueous solution.

A method for forming a therapeutic composition, comprising:
- providing an amount of first stem cells;
- culturing said first stem cells in vitro to produce one or more first stem cell released molecules;
- providing an amount of second stem cells, said second stem cells being distinct from said first stem cells;
- culturing said second stem cells in vitro to produce one or more second stem cell released molecules;
- filtering the first and second stem cell released molecules from the first and second stem cells;
- combining said first and second stem cell released molecules;
- introducing a thickening agent;
- and
- suspending said first and second stem cell released molecules and said thickening agent in an aqueous solution.
