HUMAN BONE MARROW-DERIVED MESENCHYMAL STEM CELL SHEETS AND METHODS FOR THEIR PRODUCTION

The disclosure provides a human bone marrow-derived mesenchymal stem cell (hBMSC) sheet comprising one or more layers of human hBMSCs, wherein the cell sheet is prepared from a human clonal bone marrow-derived mesenchymal stem cell line generated from a single cell. The disclosure also provides meth...

Beschreibung
Zusammenfassung:	The disclosure provides a human bone marrow-derived mesenchymal stem cell (hBMSC) sheet comprising one or more layers of human hBMSCs, wherein the cell sheet is prepared from a human clonal bone marrow-derived mesenchymal stem cell line generated from a single cell. The disclosure also provides methods for producing human bone marrow-derived mesenchymal stem cell sheets comprising culturing hBMSCs in culture solution on a temperature-responsive polymer which has been coated onto a substrate surface of a cell culture support, wherein the temperature-responsive polymer has a lower critical solution temperature in water of 0-80° C.; adjusting the temperature of the culture solution to below the lower critical solution temperature, whereby the substrate surface is made hydrophilic and adhesion of the cell sheet to the surface is weakened; and detaching the cell sheet from the culture support. The cell sheet may be treated with interferon gamma (IFN-γ) or basic fibroblast growth factor (bFGF).
