Masson staining of the four groups. (a0–a2) Masson staining of the cranial defect location repaired by Fetal-TEBG in young goats. (b0–b2) Masson staining of the cranial defect location repaired by Fetal-TEBG in aged goats. (c0–c2) Masson staining of the cranial defect location repaired by Control DBM scaffold in young goats. (d0–d2) Masson staining of the cranial defect location repaired by Control DBM scaffold in aged goats. (yellow arrow: bony tissue; red arrow: fibrous connective tissue) Scale bar: (a0, b0, c0, d0) 500 μm; (a1, a2, b1, b2, c1, c2, d1, d2) 50 μm
