Abstract

WATANABE, Ii-sei et al. Three-dimensional Characteristics of the Interface Epithelium-Connective Tissue Surface of Fingeres Lamina Propria of Cebus apella Monkey: Scanning Electron Microscopy Study. Int. J. Morphol. [online]. 2008, vol.26, n.2, pp.325-330. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022008000200013.

In the present paper were analysed the three-dimensional characteristics of the interface epithelium-connective tissue surface of finger prints of Cebus apella monkey employing the scanning electrón microscopic methods. The connective tissue core (CTC) and epithelial papillae were examined verifying the three-dimensional configuration of the tissue projections. The samples were fixed in Bouin solsution for histologic preparations and in modified Karnovsky for examine to observe in scanning electrón microscopy. After treatment in the 10% NaOH solution during 3 to 5 day s, the surface of finger prints revealed a distribution of CTC of lamina propria in situ showing original three-dimensional SEM images. The linear and circular dispositions CTC, and the furrows were clearly identified. Each pointed papilla presented a large base and longitudinal disposition of thick collagen fiber bundles and in some áreas with a complex reticular formations. The longitudinal furrows between the pointed papillae exhibited a dense layer of connective tissue and showed only low CTC or laminar in shape. The presence of numerous foramina of sweat gland were noted in three-dimensional SEM images.
