A scaffold should mimic the structure of the ECM as much as possible. As a result, 5 different fibers with diameters of 0.7, 0.9, 3, 7 and 20 μm were made into 5 kinds of scaffolds for tissue-regeneration. The scaffolds were made of Poly(glycolic acid) (PGA) nonwoven fabrics with fiber-spacing of 1.8 to 31.6 μm. This study investigated the influence of the 5 different scaffolds on infiltrating cells and granulation-formation. Six female Wistar rats underwent surgery to create 5 “pockets\" in the subcutaneous tissue of the back, and one of the 5 types of PGA scaffolds was implanted into each “pocket\". These implanted PGA scaffolds and surrounding tissues were excised en block on postoperative days 14, and then the infiltrating cells and granulation-formation were assessed microscopically. In the scaffolds with a fiber-diameters of 0.9 and 3 μm and fiber-spacing of 10.8 and 9.0 μm, respectively, dense granulation tissue was formed over the full-thickness of the scaffolds. However, in the scaffolds with fiber-diameters of 7 and 20 μm and fiber-spacing of 15.1 and 31.6 μm, respectively, a relatively sparse granulation tissue was formed only around the fiber bundles and sparse granulation tissue was observed to form in the spaces between the bundles. In the scaffolds with a fiber-diameter of 0.7 and fiber-spacing of 1.8 μm, dense granulation tissue only formed in the superficial and shallow layers of the scaffolds, and no cell-infiltration was found in the central region of the thickness. These results suggest that scaffolds with fiber-diameters smaller than 3 μm and fiber-spacing approximately 10 μm are suitable for artificial scaffolds made with PGA fibers to induce the regeneration of dense granulation tissue over the full-thickness of the scaffold.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1_description_25":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14988/pa.2017.0000012776","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_15":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"同志社大学理工学研究所","subitem_publisher_language":"ja"}]},"item_1_publisher_16":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Science
