AI Article Synopsis
Article Abstract
Environmental pollutant acrylamide has toxic effect on human health. Numerous industries such as the paper, and cosmetics, use acrylamide in their manufacturing. In certain foods, acrylamide arises at extremely high temperatures. Mesenchymal stem cells can shield different tissues from the damaging effects of free radicals induced by acrylamide. This study aimed to compare the therapeutic efficacy against acrylamide-induced toxicity between adipose-derived mesenchymal stem cells (MSCs) and their conditioned media (CM), evaluating which is more effective. Seventy adult male rats were employed in this study, distributed among 5 groups. The control group consisted of 10 rats, while each of the other four groups comprised 15 rats. The AC group received a daily oral acrylamide (AC) dosage of 3 mg/kg. In the AC + AD-MSCs and AC + AD-MSCs CM groups, after 4 weeks of AC administration, rats were injected with 0.65 × 10 AD-MSCs/0.5 ml PBS and 0.5 ml of AD-MSCs CM, respectively, via the caudal vein, and were observed for 15 days. The recovery group (Rec.), subjected to 4 weeks of AC treatment, and was allowed an additional 15 days for recuperation. The result in AC and Rec. groups revealed elevated DNA damage, P53 protein levels, apoptosis, LPO, and testosterone (free and total). In contrast, the administration of CM and the transplanting of AD-MSCs decreased the levels of these proteins. According to histological analysis, treating testicular cells with AD-MSCs mitigated histopathological lesions, fibrosis, and toxicity caused by AC. The regulation of P53, LPO protein levels, and testosterone levels, supported the function of AD-MSCs in lowering testis DNA damage and apoptosis.

Background: The simultaneous differentiation of human pluripotent stem cells (hPSCs) into both endodermal and mesodermal lineages is crucial for developing complex, vascularized tissues, yet poses significant challenges. This study explores a method for co-differentiation of mesoderm and endoderm, and their subsequent differentiation into pancreatic progenitors (PP) with endothelial cells (EC).
Methods: Two hPSC lines were utilized.

Background: Hemorrhagic shock (HS) corresponds to absolute hypovolemia creating an imbalance between oxygen supply and consumption. This causes an impaired hemostasis, a systemic inflammatory response, and microvascular permeability which can lead to multiple organ failure (MOF). There is no specific treatment for the endothelial dysfunction that plays a major role in the evolution towards MOF.

Mesenchymal Stromal/Stem Cells (MSCs) are among the most frequently studied cell types in clinical trials, and their small extracellular vesicles (sEVs) are now being extensively investigated for therapeutic applications. The RNA cargo of MSC-sEVs, particularly miRNAs and mRNAs, is widely believed to be a key therapeutic component of these vesicles. In this review, we critically examine using first principles and peer-reviewed literature, whether MSC- extracellular vesicles (MSC-EVs) can deliver sufficient quantity of functional miRNA or mRNA to target compartments within recipient cells to elicit a pharmacological response.

Senescence and osteogenic differentiation potential loss limited bone nonunion treatment effects of bone marrow-derived mesenchymal stem cells (BMSCs). MiR-100-5p/Lysine(K)-specific demethylase 6B (KDM6B) can inhibit osteogenesis, but their effects on bone union remain unclear. This study aims to investigate the effects of miR-100-5p/KDM6B on osteogenic differentiation and bone defects.

Human pluripotent stem cells (hPSCs) have at least three distinct states: naïve pluripotency that represents the cellular states of the pre-implantation epiblast cells, primed pluripotency that represents the cellular states of the post-implantation epiblast cells, and formative pluripotency that represents a developmental continuum between naïve and primed pluripotency. Various cell surface markers have been used to define and analyze primed and naïve hPSCs within heterogeneous populations. However, not much is known about common cell surface markers for the different pluripotent states of hPSCs.
