A–D CD68/Iba1 expression around the injury site after TBI in the four groups. E, F Quantitative analysis of CD68⁺ (E) and Iba1⁺ (F) cell numbers. G–J Representative TUNEL staining in the four groups. Apoptotic cells labeled with TUNEL emitted green fluorescence. K Quantitative counting of TUNEL-positive cells. ^**P < 0.01 versus TBI group, ^#P < 0.05, ^##P < 0.01 versus 3D-CH-ST group
