Abstract

The invention belongs to the technical field of corneal anatomy, and particularly discloses an application of a three-dimensional printing technology in corneal limbal tissue in-vitro three-dimensional modeling, and the method of the application comprises the steps of specimen fixation, tissue embedding and slicing, HE staining, image acquisition, digitization and three-dimensional reconstructionto obtain a three-dimensional structure digitized model of corneal limbal tissue. The reconstructed corneal limbal three-dimensional stereogram can display the microstructure of the human corneal limbal tissue, and therefore it is indicated that the method for conducting three-dimensional digital reconstruction by collecting the high-definition microscopic tissue image obtained after slice dyeingis feasible. The method combines the advantages that adjacent tissue images are easy to align under the low-power lens and tissue images under the high-power lens are clearer, is simple and practical,and can also be used for microstructure three-dimensional reconstruction of other tissues.

Description

technical field [0001] The invention relates to the technical field of corneal anatomy, in particular to the application of a three-dimensional printing technology in three-dimensional modeling of limbal tissue in vitro. Background technique [0002] The corneal limbus is the transition zone between the cornea and the sclera, about 1 mm wide, and its anatomical structure consists of epithelial cell layer and stroma layer from top to bottom. The epithelial cell layer is more than 10 layers of irregularly arranged small cylindrical cells, and part of the epithelial cells at the base protrude downwards into the matrix, while the matrix extends into the epithelial layer in a finger-like manner, forming a staggered arrangement of epithelial-matrix Vogt Palisades. Limbal stem cells are distributed in the basal cells of the Vogt palisade structure. They are adult stem cells with the ability to self-renew and differentiate into corneal epithelial cells. It is an important guarantee...
