Abstract

Optimal seeding of a nerve conduit with cells is a core problem in tissue engineering of constructing an artificial nerve substitute to gap lesions in the peripheral nerve system. An ideal nerve gap substitute would have to present an equally distributed number of cells that can activate the regrowing axons. This work shows a new in vitro technique of two-step seeding of cells inside a conduit and on layered mats that allows a valuable targeting of the cells and a proven survival in the environment of poly-3-hydroxybutyrate (PHB) conduits. The technique uses two components of diluted fibrin glue Tisseel. Initially, the chosen area on the mat was coated with thrombin followed from the seeding of a fibrinogen-cell compound. Using Sprague Dawley rat cells, we could demonstrate with immunohistochemistry (S100, DAPI) techniques that undifferentiated (uMSC) and Schwann cells (SC) mimicking differentiated mesenchymal stem cells (dMSC) as well as SC can be suspended and targeted significantly better in dissolvable diluted fibrin glue than in growth medium. Analysis showed significantly better values for adherence (p > 0.001) and drop off (p > 0.05) from seeded cells. Using this two-step application allows the seeding of the cells to be more precise and simplifies the handling of cell transplantation.
