Exosomes derived from umbilical cord mesenchymal stem cells promote healing of complex perianal fistulas in rats.
Stem Cell Res Ther
December 2024
National Colorectal Disease CenterNanjing Hospital of Chinese Medicine, Affiliated to Nanjing University of Chinese Medicine, Nanjing, 210022, Jiangsu, People's Republic of China.
Background: Complex perianal fistulas, challenging to treat and prone to recurrence, often require surgical intervention that may cause fecal incontinence and lower quality of life due to large surgical wounds and potential sphincter damage. Human umbilical cord-derived MSCs (hUC-MSCs) and their exosomes (hUCMSCs-Exo) may promote wound healing.
Methods: This study assessed the efficacy, mechanisms, and safety of these exosomes in treating complex perianal fistulas in SD rats.

Endometriosis, a gynecological disorder marked by pelvic pain and infertility, has its pathogenesis and pathophysiology significantly influenced by epigenetics, as these factors have been well characterized. However, the role of RNA-mediated epigenetic regulation in endometriosis remains to be elucidated. In our study, we found that N4-acetylcytidine (acC) RNA modification and N-acetyltransferase 10 (NAT10) were significantly upregulated in endometrial lesions compared to eutopic endometrium.

Department of Nephrology, The Third Xiangya Hospital, Central South University, Changsha, China.
Background: The involvement of microRNA-668 (miR-668) in the onset and progression of renal fibrosis remains unclear. To this end, we aimed to explore the relevant mechanism of miR-668 in renal fibrosis.
Methods: C57BL/6 J male mice were randomly divided into sham-operated, unilateral ureteral obstruction (UUO), and UUO-fenofibrate groups.

Avian pathogenic Escherichia coli (APEC) is a significant pathogen infecting poultry that is responsible for high mortality, morbidity and severe economic losses to the poultry industry globally, posing a substantial risk to the health of poultry. APEC encounters reactive oxygen species (ROS) during the infection process and thus has evolved antioxidant defense mechanisms to protect against oxidative damage. The imbalance of ROS production and antioxidant defenses is known as oxidative stress, which results in oxidative damage to proteins, lipids and DNA, and even bacterial cell death.
