Microvesicles and Exosomes Released by Amnion Epithelial Cells Under Oxidative Stress Cause Inflammatory Changes in Uterine Cells.

Biol Reprod 2021 May 7. Epub 2021 May 7.

Division of Maternal-Fetal Medicine and Perinatal Research, Department of Obstetrics and Gynecology, The University of Texas Medical Branch at Galveston, Galveston, TX 77555, USA.

Extracellular vesicles (EVs) play a crucial role in feto-maternal communication and provide an important paracrine signaling mechanism in pregnancy. We hypothesize that fetal cells-derived exosomes and microvesicles (MVs) under oxidative stress carry unique cargo and traffic through feto-maternal interface, which cause inflammation in uterine cells associated with parturition. Exosomes and MVs, from primary amnion epithelial cell (AEC) culture media under normal or oxidative stress (OS)-induced conditions, were isolated by optimized differential centrifugation method followed by characterization for size (nanoparticle tracking analyzer), shape (transmission electron microscopy), and protein markers (western blot and immunofluorescence).

Plasma lipidome profiling of newborns with antenatal exposure to Zika virus.

PLoS Negl Trop Dis 2021 Apr 30;15(4):e0009388. Epub 2021 Apr 30.

Department of Biochemistry, Institute of Chemistry, University of São Paulo, São Paulo, Brazil.

The 2015-2016 Zika virus (ZIKV) outbreak in Brazil was remarkably linked to the incidence of microcephaly and other deleterious clinical manifestations, including eye abnormalities, in newborns. It is known that ZIKV targets the placenta, triggering an inflammatory profile that may cause placental insufficiency. Transplacental lipid transport is delicately regulated during pregnancy and deficiency on the delivery of lipids such as arachidonic and docosahexaenoic acids may lead to deficits in both brain and retina during fetal development.

Rejuvenated Stem/Progenitor Cells for Cartilage Repair Using the Pluripotent Stem Cell Technology.

Bioengineering (Basel) 2021 Apr 10;8(4). Epub 2021 Apr 10.

Steadman Philippon Research Institute, Vail, CO 81657, USA.

It is widely accepted that chondral defects in articular cartilage of adult joints are never repaired spontaneously, which is considered to be one of the major causes of age-related degenerative joint disorders, such as osteoarthritis. Since mobilization of subchondral bone (marrow) cells and addition of chondrocytes or mesenchymal stromal cells into full-thickness defects show some degrees of repair, the lack of self-repair activity in adult articular cartilage can be attributed to lack of reparative cells in adult joints. In contrast, during a fetal or embryonic stage, joint articular cartilage has a scar-less repair activity, suggesting that embryonic joints may contain cells responsible for such activity, which can be chondrocytes, chondroprogenitors, or other cell types such as skeletal stem cells.
