Abstract:

Wound healing is a complex process involving close cooperation between multiple cell types. During wound healing, fibroblasts are primarily responsible for synthesis of the replacement extracellular matrix. Fibroblast therapy is under investigation in this and other laboratories for its potential use to modulate the final outcome of the wound-healing process. This study addresses the potential interactions between transplanted and host fibroblasts, using a two-dimensional mixed culture model. Our results show that fibroblasts of two different phenotypes, fetal and adult, exhibit different speeds of in vitro migration. These migration speeds are conserved in mixed cocultures, suggesting that the migratory response is an intrinsic property of the fibroblast rather than a response to juxtacrine or paracrine signals. These results have relevance for cell-based therapies in that they demonstrate that donor fibroblasts of a different phenotype may at least partially retain that phenotype in the host environment and in the presence of endogenous fibroblasts.

More about this publication?
  • Cell Transplantation publishes original, peer-reviewed research and review articles on the subject of cell transplantation and its application to human diseases. To ensure high-quality contributions from all areas of transplantation, separate section editors and editorial boards have been established. Articles deal with a wide range of topics including physiological, medical, preclinical, tissue engineering, and device-oriented aspects of transplantation of nervous system, endocrine, growth factor-secreting, bone marrow, epithelial, endothelial, and genetically engineered cells, among others. Basic clinical studies and immunological research papers are also featured. To provide complete coverage of this revolutionary field, Cell Transplantation will report on relevant technological advances, and ethical and regulatory considerations of cell transplants. Cell Transplantation is now an Open Access journal starting with volume 18 in 2009, and therefore there will be an inexpensive publication charge, which is dependent on the number of pages, in addition to the charge for color figures. This will allow work to be disseminated to a wider audience and also entitle the corresponding author to a free PDF, as well as prepublication of an unedited version of the manuscript.
