For (D), the scale bar is 200 .To model TBI in COs, we delivered the impact into COs embedded within the mouse skull and 5-Methylcytidine custom synthesis supported by the phantom brain. CCI was performed in COs at 220 DIV utilizing our newly adapted system. As sham controls, we placed the COs within the skull filled with all the phantom brain devoid of the influence. The CCI process is well-established to model moderate to severe TBI in mouse. Therefore, as a optimistic manage, we also applied CCI into a reside mouse brain to compare with COs. To assess astrogliosis, we performed immunofluorescence analysis working with glial fibrillary acid protein (GFAP) as an astrocyte marker to evaluateCells 2021, ten, 2683 Cells 2021, 10, x FOR PEER REVIEW9 of 16 11 ofFigure three.
