Isolation and Characterization of Extracellular Vesicles of Chick Embryo Blood.

Exosomes from plants or animals are a cheap, available, and promising option in medicine, which can be used for the detection or treatment of various diseases. This study aims to evaluate the antitoxic and antioxidant properties of Extracellular vesicle (EVs) extracted from chicken embryo blood using a fibroblast cell line (NIH/3T3). EVs from chick embryos were extracted in this experimental investigation using the sedimentation method and examined using dynamic light scattering (DLS) and field emission electron microscopy (FE-SEM). The protein concentration and overall antioxidant capacity of the EVs were determined using bicinchoninic acid (BCA) and antioxidant capacity (FRAP). EVs were added to NIH/3T3 cells at varying concentrations (1, 2, and 10 mg/ml), and the MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay test was used to measure cell survival. The size of the isolated EVs was confirmed to be less than 100 nm by electron microscopy and DLS. The quantity of protein in these EVs was 3200 µg/ml, and their total antioxidant capacities were 3130.17, 1914.122, and 976.9 µMol/L. The MTT test findings demonstrated that NIH/3T3 cells survived treatment with EVs (P ≤ 0.001) compared to the control group. Antioxidant-rich and protein-rich exosomes in chicken embryos may be valuable in managing oxidative stress.

Tissue Engineering Scaffolds Loaded With a Variety of Plant Extracts: Novel Model in Breast Cancer Therapy.

Despite recent improvements in detecting and managing breast cancer (BC), it continues to be a major worldwide health concern that annually affects millions of people. Exploring the anti-BC potentials of natural compounds has received a lot of scientific attention due to their multi-target mode of action and good safety profiles because of these unmet needs. Drugs made from herbs are secure and have a lot fewer negative effects than those made from synthetic materials. Early stage patients benefit from breast-conserving surgery, but the risk of local recurrence remains, necessitating implanted scaffolds. These scaffolds provide residual cancer cell killing and tailored drug delivery. This review looks at plant extract-infused tissue engineering scaffolds, which provide a novel approach to treating BC. By offering patient individualized, safer treatments, these scaffolds could completely change how BC is treated.
