Abstract

Following the advantages of single cell transplantation in comparison to sheet grafts we improved a spinning culture system for keratinocytes on completely biodegradable micro-carriers. Since previous in vivo investigations with different carrier materials (Cytodex® and PLGA) [Voigt et al. Tissue Eng 8(2):263–272, 2002; Voigt et al. Tissue Eng 5:563–572, 1999] revealed severe cellular inflammatory reactions and persistent remnants of micro-carriers in wounds, the aim of this study was to find a completely biodegradable, physiological and non-toxic material for new micro-carriers. We succeeded in setting up a keratinocyte spinning culture system using fibrin carriers. We were able to reconstitute the epidermis in full thickness wounds in an athymic nude mouse model and in an immunocompetent porcine wound model.
