Summary: A novel cell-free bioresorbable small diameter silk TEVG system functionalized with decellularized human Wharton's jelly matrix has been developed and successfully implanted into rabbit jugular vein. The implanted TEVGs remained patent for two months and integrated with host tissue, demonstrating neo-tissue formation and constructive remodeling. The functionalized silk TEVGs showed increased host cell recruitment, supported superior graft remodeling, and mimicked the usefulness of cell seeding.

Summary: Vascular regeneration relies on the proliferation and spreading of injured endothelial cells to control vascular wall thickness. Nanofibrous scaffolds prepared using various strategies, such as surface modification, co-electrospinning and blend-electrospinning, demonstrated high bioactivity in supporting endothelial cell attachment and proliferation. Incorporating somatotropin in the polyurethane fibers resulted in a sustained release pattern, enhancing endothelial cell proliferation for therapeutic purposes.

Summary: Monocytes are circulating leukocytes that interact with endothelial cells to regulate inflammation, angiogenesis, and tissue remodeling under physiological and pathophysiological conditions. They transdifferentiate into macrophages and release various substances that induce vascular and tissue remodeling or propagate inflammatory responses. The interactions between infiltrating monocytes and endothelial cells contribute to pathophysiological conditions such as cardiovascular and chronic liver diseases.

Summary: Cardiovascular diseases, as the leading cause of death worldwide, are strongly associated with overweight and obesity, which contribute to vascular dysfunction and cardiovascular diseases. The abnormal remodeling of specific adipose tissue depots during obesity plays a critical role in the development of hypertension, endothelial dysfunction, and vascular stiffness, with fat distribution being a key determinant of the risk for cardiovascular diseases.

Summary: The study successfully developed xenogeneic-free conditions for deriving functional endothelial cells from human induced pluripotent stem cells (XF-hiPSC-ECs), which exhibited similar marker expression and function to human primary ECs. Moreover, the XF-hiPSC-ECs responded to shear stress with typical cell alignment and gene expression, and were successfully used to endothelialize decellularized human vessels in a dynamic bioreactor system, advancing the potential clinical application of tissue engineered vascular grafts.

Summary: The larynx is a complex organ consisting of various muscles, cartilages, mucosal membrane, and nerves, with larynx cancer being the most common type of head and neck cancer. Treatment options are limited for patients undergoing total or partial laryngectomy, but tissue-engineered organs have shown promise as an alternative. A novel decellularization method involving perfusion-agitation with detergents and ultrasonication was used to construct a pig larynx scaffold with preserved ECM proteins and angiogenic growth factors.

Summary: The study validated the efficacy of luminal polyethylene glycol (PEG) in reducing damage to the intestinal epithelium during cold storage (CS) of intestinal grafts. Luminal PEG treatment significantly lowered mucosal injury, redistributed tight junction proteins earlier, and showed an emerging unfolding protein response after 24 hours of CS. Increased caspase activity was found in the control group, suggesting the potential of luminal PEG as a safe and effective intervention.

Summary: Literature reports successful cases of penile transplantation for cis men, with no attempts for trans men. Modern surgical techniques for penis reconstruction may have limitations, making penis transplantation a potential alternative. The study confirmed the feasibility of using the internal pudendal artery for arterial anastomosis in transplantation procedures based on measurements of diameter and length.

Summary: This study demonstrates that Wnt3a and Wnt5a may enhance the proliferation and migration of hFLPC by regulating key target genes, potentially playing an important role in liver regeneration processes. Incorporating recombinant human Wnt3a and Wnt5a in regenerative strategies using liver stem/progenitor cells could potentially improve the process of liver regeneration.
