Construction methods and latest applications of kidney cancer organoids.

Renal cell carcinoma (RCC) is one of the deadliest malignant tumors. Despite significant advances in RCC treatment over the past decade, complete remission is rarely achieved. Consequently, there is an urgent need to explore and develop new therapies to improve the survival rates and quality of life for patients.

Exosomal microRNA-Based therapies for skin diseases.

Based on engineered cell/exosome technology and various skin-related animal models, exosomal microRNA (miRNA)-based therapies derived from natural exosomes have shown good therapeutic effects on nine skin diseases, including full-thickness skin defects, diabetic ulcers, skin burns, hypertrophic scars, psoriasis, systemic sclerosis, atopic dermatitis, skin aging, and hair loss. Comparative experimental research showed that the therapeutic effect of miRNA-overexpressing exosomes was better than that of their natural exosomes. Using a dual-luciferase reporter assay, the targets of all therapeutic miRNAs in skin cells have been screened and confirmed.

Subcutaneous device-free islet transplantation.

Diabetes mellitus is a chronic metabolic disease, characterized by high blood sugar levels; it affects more than 500 million individuals worldwide. Type 1 diabetes mellitus (T1DM) is results from insufficient insulin secretion by islets; its treatment requires lifelong use of insulin injections, which leads to a large economic burden on patients. Islet transplantation may be a promising effective treatment for T1DM.

Protective effects of Chinese herbal monomers against ischemia-reperfusion injury.

Objectives: Ischemia-reperfusion injury is a complicated pathologic process that involves multiple factors including oxidative stress, endoplasmic reticulum stress, calcium overload, inflammatory response, disturbances in energy metabolism, apoptosis, and some newly-described forms of programmed cell death (e.g., necroptosis, autophagy, pyroptosis, patanatos, and ferroptosis).

Exosomal-microRNAs Improve Islet Cell Survival and Function In Islet Transplantation.

Exosomal-microRNAs (Exo-miRNAs) are key regulators of islet cell function, including insulin expression, processing, and secretion. Exo-miRNAs have a significant impact on the outcomes of islet transplantation as biomarkers for evaluating islet cell function and survival. Furthermore, they have been linked to vascular remodeling and immune regulation following islet transplantation.

Transplantation of insulin-producing cells derived from human MSCs to treat diabetes in a non-human primate model.

Background: Islet cell transplantation is an emerging therapy in the treatment of diabetes mellitus. Differentiation of islet cells from mesenchymal stem cells (MSCs) is a potential solution to the challenge of insufficient donor sources. This study investigated whether human umbilical cord-derived MSCs could effectively differentiate into insulin-producing cells (IPCs) and evaluated the therapeutic efficacy of IPCs in treating diabetes.
