The growth-associated protein 43 (GAP-43) gene of Gekko japonicus was obtained from a brain and spinal cord cDNA library. The results of northern blot analysis showed the gecko GAP-43 gene transcript is 1.7 kb in length, and it was abundantly expressed in tissues of brain, spinal cord and ovary. Gecko GAP-43 promoted the outgrowth of Gsn3 cells and PC12 cell in vitro, and phosphorylation at serine 42 modulated the effect of GAP-43 on cell spreading and morphology. The change in GAP-43 expression in the spinal cord after tail amputation was examined by reverse transcription polymerase chain reaction (RT-PCR). The level of GAP-43 in the spinal cord was increased during the time course we examined, indicating a possible correlation between GAP-43 expression and the spinal cord injury and regeneration.

Bone tissue engineering is a promising field that aims to rebuild the bone tissue using biomaterials, cells, and signaling molecules. Materials like natural and synthetic polymers, inorganic materials, and composite materials are used to create scaffolds that mimic the hierarchical microstructure of bone. Stem cells, particularly mesenchymal stem cells (MSCs), play a crucial role in bone tissue engineering by promoting tissue regeneration and modulating the immune response.

An 86-year-old male patient developed paresthesia in both hands, and six months later, pancytopenia was noted. He was diagnosed with myelodysplastic syndrome following bone marrow aspiration. Despite high serum vitamin B12 level, elevated level of serum homocysteine, positive anti-intrinsic factor antibody, and T-weighted hyperintense lesions on spinal cord MRI led to a diagnosis of subacute combined degeneration of the spinal cord.

Self-renewal capacity and potential to differentiate into almost any cell type of the human body makes pluripotent stem cells a valuable starting material for manufacturing of clinical grade cell therapies. Neurodegenerative diseases are characterized by gradual loss of structure or function of neurons, often leading to neuronal death. This results in gradual decline of cognitive, motor, and physiological functions due to the degeneration of the central nervous systems.

Purpose: Standard operating procedures aim to achieve a standardized and assumedly high-quality therapy. However, in orthopaedic surgery, the aspect of temporal urgency is often based on surgical tradition and experience. At a time of evidence-based medicine, it is necessary to question these temporal guidelines.

Background: Myelin-laden foamy macrophages accumulate extensively in the lesion epicenter, exhibiting characteristics of autophagolysosomal dysfunction, which leads to prolonged inflammatory responses after spinal cord injury (SCI). Trehalose, known for its neuroprotective properties as an autophagy inducer, has yet to be fully explored for its potential to mitigate foamy macrophage formation and exert therapeutic effects in the context of SCI.
Results: We observed that trehalose significantly enhances macrophage phagocytosis and clearance of myelin in a dose-dependent manner in vitro.
