Abstract: A cell culture medium is disclosed. The cell culture medium comprises: a species-specific cell culture medium comprising: bFGF of the species, PDGF-BB of the species, and EGF of the species; and serum of the species. Further disclosed is a canine cell culture medium comprising: canine bFGF, canine PDGF-BB, and canine EGF; and canine serum. A composition is described comprising: a medium comprising: basal medium, sodium bicarbonate, HEPES, L-glutamine, L-alanine, Insulin, hydrocortisone, progesterone, Asc-2-p, holo-transferrin; bFGF of the species, PDGF-BB of the species, and EGF of the species; and serum consistent with the cells of the species; MSC cells of the species. A method of producing exosomes is described, the method comprising: expanding mesenchymal stem cells and/or islet cells in culture, the culture and collecting exosomes released by the mesenchymal and/or adipose stem cells in culture.

Abstract: Provided are compositions and methods of treating impaired glucose tolerance which substantially increase the islet donor pool and safety as well as remove the need for anti-rejections drugs. Described are methods of making cell clusters comprising: expanding pancreatic islet cells; and forming cell clusters comprising: the expanded islet cells and mesenchymal/adipose stem cells. Expansion of the islet cells may include=>five population doublings. The islet cells may be primary islet cells obtained from an adult, non-diabetic donor having a North America Islet Donor Score (NAIDS) of <80. Described are cell clusters produced by the methods.

Abstract: The present disclosure relates to compositions for the treatment of microvascular diseases. Such compositions may comprise mesenchymal and/or adipose stem cells; and/or exosomes isolated from mesenchymal and/or adipose stem cells. Further included are methods of treating microvascular disease using the compositions and methods of making the compositions.
