Physical modulation of mesenchymal stem cell exosomes: A new perspective for regenerative medicine.

Mesenchymal stem cell-derived exosomes (MSC-Exo) offer promising therapeutic potential for various refractory diseases, presenting a novel therapeutic strategy. However, their clinical application encounters several obstacles, including low natural secretion, uncontrolled biological functions and inherent heterogeneity. On the one hand, physical stimuli can mimic the microenvironment dynamics where MSC-Exo reside.

TLR8 aggravates skin inflammation and fibrosis by activating skin fibroblasts in systemic sclerosis.

Objectives: Innate immunity significantly contributes to SSc pathogenesis. TLR8 is an important innate immune mediator that is implicated in autoimmunity and fibrosis. However, the expression, mechanism of action, and pathogenic role of TLR8 in SSc remain unclear.

Adipose-derived mesenchymal stem cell therapy for reverse bleomycin-induced experimental pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive respiratory disease. Arguably, the complex interplay between immune cell subsets, coupled with an incomplete understanding of disease pathophysiology, has hindered the development of successful therapies. Despite efforts to understand its pathophysiology and develop effective treatments, IPF remains a fatal disease, necessitating the exploration of new treatment options.

Trends in cutaneous squamous cell carcinoma on the lip incidence and mortality in the United States, 2000-2019.

Objective: This study provided a systematic analysis of the trend in incidence and incidence-based mortality for cutaneous squamous cell carcinoma (cSCC) on the lips in the USA using demographic characteristics from the Surveillance, Epidemiology, and End Results (SEER) database.

Methods: Patients diagnosed with cSCC on the lips between 2000 and 2019 from the 17 registries of the USA were identified. Incidence and incidence-based mortality rates were analyzed using SEER*Stat 8.

Therapeutic applications of adipose-derived stromal vascular fractions in osteoarthritis.

Osteoarthritis (OA) is considered to be a highly heterogeneous disease with progressive cartilage loss, subchondral bone remodeling, and low-grade inflammation. It is one of the world's leading causes of disability. Most conventional clinical treatments for OA are palliative drugs, which cannot fundamentally cure this disease.

Stem Cell-Derived Exosomes: A New Method for Reversing Skin Aging.

Senescence is an inevitable natural life process that involves structural and functional degeneration of tissues and organs. Recently, the process of skin aging has attracted much attention. Determining a means to delay or even reverse skin aging has become a research hotspot in medical cosmetology and anti-aging.

Metabolic syndrome and its components are associated with hypoxemia after surgery for acute type A aortic dissection: an observational study.

Background: The aim of this study was to explore whether or to what extent metabolic syndrome (METs) and its components were associated with hypoxemia in acute type A aortic dissection (ATAAD) patients after surgery.

Methods: This study involved 271 inpatients who underwent surgery. Demographic and clinical data were collected.

Emodin suppresses hepatocellular carcinoma growth by regulating macrophage polarization via microRNA-26a/transforming growth factor beta 1/protein kinase B.

Accumulating evidence has demonstrated that M2 macrophages contribute to the progression of hepatocellular carcinoma (HCC). Emodin is an anti-tumor agent and potentially regulates macrophage polarization. This study aims to explore the effect of emodin on M2 polarization in HCC and its underlying mechanism.

Adipose-Derived Stem Cell Exosomes Promoted Hair Regeneration.

Background: Some scholars have found that dermal papilla spheroid-derived exosomes could promote the development of hair follicles. However, whether adipose-derived stem cell exosomes (ADSC-Exos) have a similar effect on hair growth has not been determined yet. Thus, the purpose of this article was to detect whether ADSC-Exos could promote hair regeneration.

Therapeutic application of adipose-derived stromal vascular fraction in diabetic foot.

Diabetic foot is one of the severest complications of diabetes. In severe cases, this disease may be lead to amputation or even death due to secondary infection and ischemic necrosis. Since the ineffectiveness of traditional therapy, autologous stem cell transplantation has been used to treat diabetic foot.

Physiological and subjective responses after psychosocial stress in Chinese hepatitis B patients.

Compared with healthy participants, Chinese patients with hepatitis B (HB) experience more psychosocial stress. The present study provided the first examination of physiological and subjective responses to stress in Chinese HB patients. A standard psychosocial stressor, the Trier Social Stress Test (TSST), was administered to 26 Chinese HB patients and 24 healthy control participants.
