The present work was performed to determine the ability of neurotrophic factors to allow axonal regeneration across a 15-mm-long gap in the rat sciatic nerve. Synthetic nerve guidance channels slowly releasing NGF and GDNF were fabricated and sutured to th ...
Neural stem cells (NSCs), when stimulated with epidermal growth factor (EGF) or fibroblast growth factor-2 (FGF-2), have the capacity to renew, expand, and produce precursors for neurons, astrocytes, and oligodendrocytes. We postulated that the early appea ...
In vertebrates, different isoforms of fibroblast growth factor 2 (FGF2) exist, which differ by their N-terminal extension. They show different localization and expression levels and exert distinct biological effects. Nevertheless, genetic inactivation of a ...
Dorsal roots have a limited regeneration capacity after transection. To improve nerve regeneration, the growth-promoting effects of the neurotrophins nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), and neurotrophin-3 (NT-3) were evalua ...
The goal of this work was to develop a growth factor delivery system for use in wound healing that would provide localized release of heparin-binding growth factors in a biomimetic manner, such that release occurs primarily in response to cell-assocd. enzy ...
A novel method for the delivery of growth factor proteins from fibrin matrixes was developed. Nerve growth factor (NGF) fusion proteins contg. an exogenous transglutaminase substrate at the N-terminus of the protein were made recombinantly by E. coli. The ...
Fibrin plays an important role in wound healing and regeneration, and enjoys widespread use in surgery and tissue engineering. The enzymatic activity of Factor XIIIa was employed to covalently incorporate exogenous bioactive peptides within fibrin during c ...
The goal of this work was to improve the potential of fibrin to promote nerve regeneration by enzymatically incorporating exogenous neurite-promoting heparin-binding peptides. The effects on neurite extension of four different heparin-binding peptides, der ...
Motoneurons of the neonate rat respond to proximal axonal injury with morphologic and functional changes and ultimately with neuronal death. Recent studies showed that both glial cell-line-derived neurotrophic factor (GDNF) and brain-derived neurotrophic f ...
Regulation of calbindin and calretinin expression by brain-derived neurotrophic factor (BDNF) was examined in primary cultures of cortical neurons using immunocytochemistry and northern blot analysis. Here we report that regulation of calretinin expression ...
