Combining Innovative Bioink and Low Cell Density for the Production of 3D-Bioprinted Cartilage Substitutes: A Pilot Study by Christel Henrionnet, Léa Pourchet, Paul Neybecker, Océane Messaoudi, Pierre Gillet, Damien Loeuille, Didier Mainard, Christophe Marquette, Astrid Pinzano

“…We present herein the development of cartilage implants by 3D bioprinting that deliver MSCs encapsulated in an original bioink at low concentration. 3D-bioprinted constructs (10×10×4 mm) were printed using alginate/gelatin/fibrinogen bioink mixed with human bone marrow MSCs. The influence of the bioprinting process and chondrogenic differentiation on MSC metabolism, gene profiles, and extracellular matrix (ECM) production at two different MSC concentrations (1 million or 2 million cells/mL) was assessed on day 28 (D28) by using MTT tests, real-time RT-PCR, and histology and immunohistochemistry, respectively. …”

T Cell-Derived Apoptotic Extracellular Vesicles Ameliorate Bone Loss via CD39 and CD73-Mediated ATP Hydrolysis by Yang X, Zhou Y, Zhou F, Bao L, Wang Z, Li Z, Ding F, Kuang H, Liu H, Tan S, Qiu X, Jing H, Liu S, Ma D

“…We observed increased levels of extracellular ATP and a decrease in CD39 and CD73, key enzymes in ATP-to-adenosine conversion in bone marrow of OVX mice. We found that ApoEVs are enriched with CD39 and CD73 on their membranes, which enable the hydrolysis of extracellular ATP to adenosine both in vitro and in vivo. …”
