Reports Outline Stem Cells Study Findings from Soochow University (Collagen Nanofibers Facilitated Presynaptic Maturation in Differentiated Neurons from Spinal-Cord-Derived Neural Stem Cells through MAPK/ERK1/2-Synapsin I Signaling Pathway)

By a News Reporter-Staff News Editor at Biotech Week -- Investigators publish new report on Stem Cell Research. According to news originating from Suzhou, People's Republic of China, by NewsRx correspondents, research stated, "Neural stem cells (NSCs) are deemed to be a potential cell therapy for brain and spinal cord reconstruction and regeneration following injury. In this study, we investigated the role of nanofibrous scaffolds on NSCs-derived neurons in the formation of neural networks."

Our news journalists obtained a quote from the research from Soochow University, "Miniature excitatory postsynaptic currents (mEPSCs) were recorded using the whole-cell patch clamp recording method after the spinal cord-derived NSCs were differentiated into neurons and cultured in vitro for 10-14 days. It was observed that the frequency of mEPSCs in the differentiated neurons cultured on both randomly oriented and aligned collagen nanofibrous scaffolds was higher than that on the collagen-coated control and can be inhibited by an ERK inhibitor (PD98059), indicating that the collagen nanofibers affected the maturation of the synapses from presynaptic sites via the MAPK/ERK1/2 pathway."

According to the news editors, the research concluded: "In addition, both of the collagen nanofibers increased the phosphorylation of Synapsin I and facilitated the interaction of p-ERK1/2 and p-Synapsin I. All these results suggested that the collagen nanofibrous scaffolds contributed to the presynaptic maturation via the ERK1/2-Synapsin I signaling pathway."
