Ultrastructure and Light Microscope Analysis of Intact Skin after a Varying Number of Low Level Laser Irradiations in Mice
Figure 1
(a)–(c) Control group. (a) Epidermis with keratinocytes (*) and corneum (c) layer (×4000). (b) Basal cell layer with loose chromatin nuclei (n), joined by desmosomes (arrow head) showing intermediate keratin filaments (×10000). (c) Granular cell layer (g) with keratohyalin granules (arrow) surrounded by ribosomes and thick electron dense plasm a membrane (*) (×10000). (d)–(f) Irradiated group. (d) Epidermis (e), the dermis (*), and dilated channels (arrow) between keratinocytes of the metabolically active layer (×4000). (e) Basal keratinocytes layer jointed by desmosomes (arrow head) showing the nucleus (n) and bundle of keratin fibrils (×10000). (f) Granular keratinocytes layer with abundant keratohyalin granules (arrow), thick electron dense plasma membrane (*) with vesicles suggesting lamellar granules exuding their contents, and corneum layer keratinocytes (c) (×10000).
