Objective: To study the neurotrophic effects of protocatechuic acid on neurite outgrowth and survival in cultured cerebral cortical neurons.
Methods: The newborn rat cerebral cortex neurons were cultured in vitro. The convert phase microscope was used to count the survival neurons with neurites and measure the average length of neurites. MTT and LDH assay were carried out to investigate the effect of PCA on the neuronal viability.
Results: Compared with control group, different concentration of PCA could increase the number of survival neurons with neurites and the average length of neurites. MTT and LDH assay showed that PCA promoted neuron survival in a dose-dependent manner.
Conclusion: PCA can enhance the survival of rat cortical neurons with neurites and promote the neurite outgrowth of rat cortical neurons.

Olfactory ensheathing cell (OEC) transplantation demonstrates promising therapeutic results in neurological disorders, such as spinal cord injury. The emerging cell-free secretome therapy compensates for the limitations of cell transplantation, such as low cell survival rates. However, the therapeutic benefits of the human OEC secretome remain unclear.

Induced pluripotent stem cell (iPSC)-derived neurons (iNs) have been widely used as models of neurodevelopment and neurodegenerative diseases. Coating cell culture vessels with extracellular matrixes (ECMs) gives structural support and facilitates cell communication and differentiation, ultimately enhances neuronal functions. However, the relevance of different ECMs to the natural environment and their impact on neuronal differentiation have not been fully characterized.

In neurons, the acquisition of a polarized morphology is achieved upon the outgrowth of a single axon from one of several neurites. Small extracellular vesicles (sEVs), such as exosomes, from diverse sources are known to promote neurite outgrowth and thus may have therapeutic potential. However, the effect of fibroblast-derived exosomes on axon elongation in neurons of the central nervous system under growth-permissive conditions remains unclear.

Purpose: To investigate the therapeutic potential of eliminating insulin-like growth factor-binding protein 5 (IGFBP5) expression in improving erectile function in mice with cavernous nerve injury (CNI)-induced erectile dysfunction (ED).
Materials And Methods: Eight-week-old male C57BL/6 mice were divided into four groups: a sham-operated group and three CNI-induced ED groups. The CNI-induced ED groups were treated with intracavernous injections 3 days before the CNI procedure.

Recent advancements in tissue engineering have promoted the development of nerve guidance conduits (NGCs) that significantly enhance peripheral nerve injury treatment, improving outcomes and recovery rates. However, utilising tailored biomimetic three-dimensional (3D) topological porous structures combined with multiple bio-effect neurotrophic factors to create environments similar to neural tissues, regulate local immune responses, and develop a supportive microenvironment to promote peripheral nerve regeneration and repair poses significant challenges. Herein, a biomimetic extracellular matrix (ECM) NGC featuring an interconnected 3D porous network and sustained delivery of insulin-like growth factor-1 (IGF-1) is designed using multi-functional gelatine microcapsules (GMs).
