Identification of Proteins in Fluid Collected from Nerve Regeneration Chambers
نویسندگان
چکیده
We examined whether there are novel neurotrophic factors (NTFs) in nerve regeneration conditioned fluid (NRCF). Nerve regeneration chamber models were established in the sciatic nerves of 25 New Zealand rabbits, and NRCF was extracted from the chambers l week postoperatively. Proteins in NRCF were separated by native polyacrylamide gel electrophoresis (PAGE), and Western blot and ELISA were used to identify the proteins. A novel NTF was identified in a protein fraction corresponding to 220 kDa.

iTRAQ-based proteomics profiling of Schwann cells before and after peripheral nerve injury
Objective(s): Schwann cells (SCs) have a wide range of applications as seed cells in the treatment of nerve injury during transplantation. However, there has been no report yet on kinds of proteomics changes that occur in Schwann cells before and after peripheral nerve injury.Materials and Methods: Activated Schwann cells (ASCs) and normal Schwann cells (NSCs) were obtained from adult Wistar ra...
متن کاملThe effect of chick embryo amniotic fluid on sciatic nerve regeneration of rats
The purpose of this experimental study was to evaluate the effect of chicken amniotic fluid (AF) on a cross section of rat sciatic nerves. Thirty adult male Sprague-Dawley rats weighing 275 to 300 g, were randomized into three groups treated with (1) amniotic fluid or AF (n=10), (2) normal saline or NS (n=10), and (3) sham surgery (n=10). The AF was aspirated from the amniotic cavity of incubat...
متن کاملThe role of the desert hedgehog signaling pathway during degeneration and regeneration of peripheral nerves
The desert hedgehog (Dhh) signaling pathway is involved in the development of peripheral nerves (PNs). Dhh-null mice show abnormal neuronal development and perineurial barrier function. As it was previously shown that dhh is mainly expressed in developmental nerves and Sonic hedgehog protein (dhh homologous) has therapeutic effects in neuronal survival, we attempted to investigate the possible ...

متن کاملIdentification of excretory-secretory products from larval stages of Ostertagia circumcincta cultured in vitro by SDS-PAGE and immunoblotting
Exsheathing fluid (EF) and excretory-secretory products (ES) of infective third-stage cultured larvae ofOstertagia circumcincta were analysed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDSPAGE). Five and seven predominant proteins were found in the EF and ES products, respectively. Immunoblotting by sheep pre-infection serum did not react with any of the EF and ES proteins, b...
