Abstract
Fibrin microbeads are prepared containing extensively cross-linked fibrin (ogen) without using glutaraldehyde. The fibrin microbeads are preferably prepared by containing an aqueous solution containing fibrinogen, thrombin and Factor XIII with an oil heated to about 50-80° C. to form an emulsion and mixing the emulsion at 50-80° C. until fibrin microbeads containing extensively cross-linked fibrin (ogen) are obtained. The fibrin microbeads may have a diameter of about 50-200 microns and can contain a bioactive agent. The fibrin microbeads are used for binding cells such as when culturing or separating one cell type from another, or when transplanting cells or engineering tissue.
