CCI Induces Astrogliosis and Reduces Neurons in COs pictures except (D). For (D), the scale bar is 200 .To model TBI in COs, we delivered the impact into COs embedded in the mouse skull and supported by the phantom brain. CCI was performed in COs at 220 DIV working with our newly adapted technique. As sham controls, we placed the COs in the skull filled using the phantom brain with out the effect. The CCI method is well-established to model moderate to severe TBI in mouse. Thus, as a positive manage, we also applied CCI into a reside mouse brain to examine with COs. To assess astrogliosis, we performed immunofluorescence analysis employing glial fibrillary acid protein (GFAP) as an astrocyte marker to evaluateCells 2021, ten, 2683 Cells 2021, ten, x FOR PEER REVIEW9 of 16 11 ofFigure 3.
