Abstract
Radiotherapy is one of the main cancer treatments, but it may damage normal tissue and cause various side effects. At present, radioprotective agents used in clinics have side effects such as nausea, vomiting, diarrhea and hypotension, which limit their clinical application. It has been found that exosomes play an indispensable role in radiation injury. Exosomes are lipid bilayer vesicles that carry various bioactive substances, such as proteins, lipids and microRNA (miRNA), that play a key role in cell-to-cell communication and affect tissue injury and repair. In addition, studies have shown that radiation can increase the uptake of exosomes in cells and affect the composition and secretion of exosomes. Here, we review the existing studies and discuss the effects of radiation on exosomes and the role of exosomes in radiation injury, aiming to provide new insights for the treatment of radiation injury.

J Clin Med 2020; 9:jcm9030766.

Abstract
Interstitial cystitis/bladder pain syndrome (IC/BPS) is a multifactorial, chronic disease without definite etiology characterized by bladder-related pelvic pain. IC/BPS is associated with pain that negatively affects the quality of life. There are various therapeutic approaches against IC/BPS. However, no efficient therapeutic agent against IC/BPS has been discovered yet. Urothelium dysfunction is one of the key factors of IC/BPS-related pathogenicity. Stem cells, including adult stem cells (ASCs) and pluripotent stem cells (PSCs), such as embryonic stem cells (ESCs) and induced PSCs (iPSCs), possess the abilities of self-renewal, proliferation, and differentiation into various cell types, including urothelial and other bladder cells. Therefore, stem cells are considered robust candidates for bladder regeneration. This review provides a brief overview of the etiology, pathophysiology, diagnosis, and treatment of IC/BPS as well as a summary of ASCs and PSCs. The potential of ASCs and PSCs in bladder regeneration via differentiation into bladder cells or direct transplantation into the bladder and the possible applications in IC/BPS therapy are described in detail. A better understanding of current studies on stem cells and bladder regeneration will allow further improvement in the approaches of stem cell applications for highly efficient IC/BPS therapy.

Abstract
Bladder acellular matrix graft-alginate dialdehyde-gelatin hydrogel-silk mesh (BAMG-HS) encapsulated with adipose-derived stem cells (ASCs) was evaluated in a rat model of augmentation cystoplasty, including BAMG-HS-ASCs (n = 18, subgroup n = 6 for 2, 4, and 12 weeks), acellular BAMG-HS (n = 6 for 12 weeks) and cystotomy control (n = 6 for 12 weeks) groups. Equipped with good cytocompatibility and superior mechanical properties (elastic modulus: 5.33 ± 0.96 MPa, maximum load: 28.90 ± 0.69 N), BAMG-HS acted a trilayer "sandwich" scaffold with minimal interference in systemic homeostasis. ASCs in BAMG-HS promoted morphological and histological bladder restoration by accelerating scaffold degradation (p < 0.05), ameliorating fibrosis (p < 0.05) and inflammation (p < 0.01). Additionally, ASCs facilitated the recovery of bladder function by enhancing smooth muscle regeneration (p < 0.05), innervation (p < 0.01) and angiogenesis (p < 0.001). Except for a small number of endothelium-differentiated ASCs, the pro-angiogenic effects of ASCs were mainly related to ERK1/2 phosphorylation in the downstream of SDF-1α/CXCR4 pathway.

Bone Marrow Stem/Progenitor Cells Attenuate the Inflammatory Milieu Following Substitution Urethroplasty. Sci Rep 2016; 6:35638.

Abstract
Substitution urethroplasty for the treatment of male stricture disease is often accompanied by subsequent tissue fibrosis and secondary stricture formation. Patients with pre-existing morbidities are often at increased risk of urethral stricture recurrence brought upon in-part by delayed vascularization accompanied by overactive inflammatory responses following surgery. Within the context of this study, we demonstrate the functional utility of a cell/scaffold composite graft comprised of human bone marrow-derived mesenchymal stem cells (MSC) combined with CD34+ hematopoietic stem/progenitor cells (HSPC) to modulate inflammation and wound healing in a rodent model of substitution urethroplasty. Composite grafts demonstrated potent anti-inflammatory effects with regards to tissue macrophage and neutrophil density following urethral tissue analyses. This was accompanied by a significant reduction in pro-inflammatory cytokines TNFα and IL-1β and further resulted in an earlier transition to tissue remodeling and maturation with a shift in collagen type III to I. Grafted animals demonstrated a progressive maturation and increase in vessel size compared to control animals. Overall, MSC/CD34+ HSPC composite grafts reduce inflammation, enhance an earlier transition to wound remodeling and maturation concurrently increasing neovascularization in the periurethral tissue. We demonstrate the feasibility and efficacy of a stem cell-seeded synthetic graft in a rodent substitution urethroplasty model.
