For this purpose, an alkali-burn lesion was induced in 15 rabbits. A week later, clinical events were evaluated and rabbits were divided into five treatment groups: rabbits treated with medical treatment, with a fibrin-PRGF membrane cultured with autologous or heterologous rabbit Limbal Epithelial Progenitor Cells (LEPCs), with a fibrin-PRGF membrane in a Simple Limbal Epithelial Transplantation and with a fibrin-PRGF membrane without cultured LEPCs. After 40 days of follow-up, corneas were subjected to histochemical examination and immunostaining against corneal or conjunctival markers. Seven days after alkali-burn lesion, it was observed that rabbits showed opaque cornea, new blood vessels across the limbus penetrating the cornea and epithelial defects. At the end of the follow-up period, an improvement of the clinical parameters analyzed was observed in transplanted rabbits. However, only rabbits transplanted with cultured LEPCs were positive for corneal markers. Otherwise, rabbits in the other three groups showed positive staining against conjunctival markers. In conclusion, fibrin-PRGF membrane improved the chemically induced lesions. Nonetheless, only fibrin-PRGF membranes cultured with rabbit LEPCs were able to restore the corneal surface.<\/p>\n<\/div>\n<p><strong class=\"sub-title\">Keywords:\u00a0<\/strong>PRP; alkali-burn lesion; fibrin-PRGF membrane; in vitro expansion; limbal stem cell.<\/p>\n<\/div>\n<\/div>\n<p>[\/vc_column_text][vc_empty_space][vc_column_text]<\/p>\n<h3>Figures<\/h3>\n<p>[\/vc_column_text][vc_empty_space][\/vc_column][\/vc_row][vc_row content_placement=&#8221;middle&#8221; content_text_aligment=&#8221;center&#8221;][vc_column]<div class=\"qodef-image-gallery qodef-grid-list qodef-disable-bottom-space  qodef-ig-grid-type qodef-four-columns qodef-tiny-space  qodef-image-behavior-lightbox\">\n\t<div class=\"qodef-ig-inner qodef-outer-space\">\n\t\t\t\t\t<div class=\"qodef-ig-image qodef-item-space\">\n\t\t\t\t<div class=\"qodef-ig-image-inner\">\n\t\t\t\t\t\t\t\t\t\t\t<a itemprop=\"image\" class=\"qodef-ig-lightbox\" href=\"https:\/\/www.btitrainingcenter.com\/wp-content\/uploads\/2021\/08\/ijms-22-05564-g001.jpeg\" data-rel=\"prettyPhoto[image_gallery_pretty_photo-789]\" title=\"&lt;strong&gt;Figure 01&lt;\/strong&gt; Phase-contrast microscopy of autologous (A) or heterologous (B) rabbit LEPCs cultured on a fibrin-PRGF membrane displaying their typical polyhedral morphology.
