Although preclinical models of spinal cord injury have shown that matrix inclusion in stem cell therapy leads to greater neurological improvements than that including cells alone, there has been insufficient matrix optimization for human cells. -Cadherin influences the development and maintenance of neural tissue, but the effects of -cadherin derived peptide His-Ala-Val-Asp-Ile (HAVDI) on the survival, neurite extension, and expression of neural differentiation markers in human induced pluripotent stem cell derived neural stems (hNSC) have not been widely examined. Using polyethylene glycol hydrogels containing a continuous gradient of HAVDI, this study identifies concentration dependent effects on hNSC survival and neural differentiation.

Histological effects of combined therapy involving scar resection, decellularized scaffolds, and human iPSC-NS/PCs transplantation in chronic complete spinal cord injury.

Chronic complete spinal cord injury (SCI) is difficult to treat because of scar formation and cavitary lesions. While human iPS cell-derived neural stem/progenitor cell (hNS/PC) therapy shows promise, its efficacy is limited without the structural support needed to address cavitary lesions. Our study investigated a combined approach involving surgical scar resection, decellularized extracellular matrix (dECM) hydrogel as a scaffold, and hNS/PC transplantation.

Small intestinal organoids are similar to actual small intestines in structure and function and can be used in various fields, such as nutrition, disease, and toxicity research. However, the basal-out type is difficult to homogenize because of the diversity of cell sizes and types, and the Matrigel-based culture conditions. Contrastingly, the apical-out form of small intestinal organoids is relatively uniform and easy to manipulate without Matrigel.

Febrile neutropenia is a major complication in patients with acute leukemia or those undergoing hematopoietic stem cell transplantation (HSCT). Understanding patient characteristics and susceptibility patterns in febrile neutropenia is essential for appropriate antimicrobial therapy. First-line agents should have Pseudomonas aeruginosa coverage, but with the increase in multi-drug resistant organisms, ceftazidime-avibactam has emerged as a new therapeutic option.

The senescence of mesenchymal stem cells (MSCs) is closely related to aging and degenerative diseases. Curcumin exhibits antioxidant and anti-inflammatory effects and has been extensively used in anti-cancer and anti-aging applications. Studies have shown that curcumin can promote osteogenic differentiation, autophagy and proliferation of MSCs.

Signaling interplay between the histamine 1 receptor (H1R) and transient receptor potential cation channel subfamily V member 1 (TRPV1) in mediating histaminergic itch has been well-established in mammalian models, but whether this is conserved in humans remains to be confirmed due to the difficulties in obtaining human sensory neurons (SNs) for experimentation. Additionally, previously reported species-specific differences in TRPV1 function indicate that use of human SNs is vital for drug candidate screening to have a higher chance of identifying clinically effective TRPV1 antagonists. In this study, we built a histamine-dependent itch model using peripheral SNs derived from human induced pluripotent stem cells (hiPSC-SNs), which provides an accessible source of human SNs for pre-clinical drug screening.
