Dermal skin-derived fibroblasts from rodent and human have been found to exhibit mesenchymal surface antigen immunophenotype and differentiation potential along the three main mesenchymal-derived tissues: bone, cartilage and fat. Human dermal skin-derived mesenchymal stem cells constitute a promising cell source in clinical applications. Therefore, we(More)
Stem cell-like keratinocytes are responsible for the high regenerative potential of the skin. For clinical applications using keratinocytes in artificial skin constructs, it is suitable to work with serum-free medium under defined conditions. This is also true for the preceding expansion of the stem cell-like keratinocyte population. Therefore, we analyzed(More)
Most small-colony termites live confined within a single piece of wood on which they feed and do not possess permanent workers: Tasks are done by developmentally flexible immatures (pseudergates). By contrast, large-colony termites possess a specialized (true) worker caste and forage outside their nest for food. To shed light on possible transitional steps(More)
An integral component of the manufacture of a skin substitute is the cryopreservation of the complete skin construct. Under this demand, investigations were carried out in the present work in the case of cryopreservation of human fibroblasts and keratinocytes composed to organotypical skin substitutes (OTS). Two scaffolds made up of gelatine and(More)
