Fig. 3From: Transient immune activation without loss of intraepidermal innervation and associated Schwann cells in patients with complex regional pain syndromeIntraepidermal Schwann cells in human glabrous skin. Skin biopsies from the index finger at the border between glabrous and hairy skin were immunolabelled. A, B, C Representative images of intraepidermal Schwann cell processes (S100+), intraepidermal nerve fibres (IENFs, PGP9.5+), Langerhans cells (CD207+), and the epidermal-dermal border (collagen IV, Coll IV+). Nerve fibres crossing the epidermal-dermal border (dashed lines) were counted as IENF (arrows), S100-positive Schwann cell processes co-localized with them (arrowheads). S100-positive Langerhans cells close to the epidermal-dermal border were excluded (asterisk). Scale bars = 50 µmBack to article page
