Scanning electron microscopy of herniated disc tissue: A Single cell I with surrounding, newly formed extracellular matrix II of the recurrent sequestration tissue of a patient after conventional treatment (group-3). At III strong material contrast due to fat accumulation; B Cell agglomerate with spindle-shaped cells IV embedded in dense matrix tissue V in recurrent sequester tissue after ADCT (group-1); C Cell agglomerate strongly contrasted with the surrounding area in recurrent sequester tissue after ADCT treatment (group-1); D Individual particles (VII small particles with a diameter of 1 µm and VIII large particles with a diameter of 10 µm) with no apparent substructure in recurrent sequester tissue after ADCT (group-1)
