Adipose stromal cells (ASC) can protect neurons when administered to brains due to secreted trophic factors. Our previous studies demonstrated that several neurotrophic factors such as brain-derived neurotropic factor (BDNF) and insulin like growth factor-1 (IGF-1) in ASC conditioned media (ASC-CM) can protect brains against hypoxic-ischemic (HI) injury in neonatal rats. In this study, we demonstrated that human ASC-CM potently blockeds caspase-3 mediated cortical neuronal apoptosis under in vitro oxygen-glucose deprivation (OGD). Interestingly, tissue inhibitor of metalloproteinase 1 (TIMP1), a non neurotrophic factor, played a significant role in the ASC-CM-induced neural protection against OGD. Thus, this study establishes the therapeutic potential of TIMP1 together with other neurotrophic factors in ASC-CM for treating cerebral HI disorders.

Extracellular vesicles (EVs), membrane-encapsulated nanoparticles shed from all cells, are tightly involved in critical cellular functions. Moreover, EVs have recently emerged as exciting therapeutic modalities, delivery vectors, and biomarker sources. However, EVs are difficult to characterize, because they are typically small and heterogeneous in size, origin, and molecular content.

Background And Aims: Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterised by progressive biliary inflammation and fibrosis, leading to liver cirrhosis and cholangiocarcinoma. GPBAR1 (TGR5) is a G protein-coupled receptor for secondary bile acids. In this study, we have examined the therapeutic potential of BAR501, a selective GPBAR1 agonist in a PSC model.

Anaplastic thyroid cancer (ATC) is a lethal endocrine malignancy. It has been shown that tumor-associated macrophages (TAMs) contribute to the aggressiveness of ATC. However, stimulatory factors that could facilitate the induction and infiltration of TAMs in the ATC tumor microenvironment (TME) are not fully elucidated.

Sepsis is a risk factor associated with increasing neonatal morbidity and mortality, acute lung injury, and chronic lung disease. While stem cell therapy has shown promise in alleviating acute lung injury, its effects are primarily exerted through paracrine mechanisms rather than local engraftment. Accumulating evidence suggests that these paracrine effects are mediated by mesenchymal stem cell (MSC)-derived small extracellular vesicles (sEVs), which play a critical role in immune system modulation and tissue regeneration.

Extracellular vesicles (EVs) are lipid bilayer-bound particles released from cells that cannot replicate on their own, play a crucial role in intercellular communication, and are implicated in various physiological and pathological processes. Within the domain of embryo culture media research, extensive studies have been conducted to evaluate embryo viability by analyzing spent culture medium. Advanced methodologies such as metabolomic profiling, proteomic and genomic analyses, transcriptomic profiling, non-coding RNA assessments, and oxidative status measurements have been employed to further understand the molecular characteristics of embryos and improve selection criteria for successful implantation.
