Interestingly, the composition of blood plasma is very similar to tears. Therefore, different blood-derived products like autologous serum (AS) and plasma rich in growth factors (PRGF) have been developed for the treatment of diverse ocular pathologies. However, scarce studies have been carried out to analyze the differences between both types of blood-derived products. In the present study, blood from three healthy donors was drawn and processed to obtain AS and PRGF eye drops. Then, human corneal stromal keratocytes (HK) were treated with PRGF or undiluted AS. Proteomic analysis was carried out to analyze and characterize the differential protein profiles between PRGF and AS, and the differentially expressed proteins in HK cells after PRGF and AS treatment. The results obtained in the present study show that undiluted AS induces the activation of different pathways related to an inflammatory, angiogenic, oxidative stress and scarring response in HK cells regarding PRGF. These results suggest that PRGF could be a better alternative than AS for the treatment of ocular surface disorders.<\/p>\n<\/div>\n<p><strong class=\"sub-title\">Keywords:\u00a0<\/strong>AS; PRGF; PRP; autologous serum; cornea; keratocytes; ocular surface; plasma rich in growth factors; platelet-rich plasma; proteomic.<\/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-22-12176-g001.jpg\" data-rel=\"prettyPhoto[image_gallery_pretty_photo-467]\" title=\"&lt;strong&gt;Figure 01&lt;\/strong&gt; Venn diagram comparison of two blood-derived fractions and the list of proteins specific for PRGF and AS.\">\n\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.btitrainingcenter.com\/wp-content\/uploads\/2021\/08\/ijms-22-12176-g001-200x200.jpg\" alt=\"\" width=\"200\" height=\"200\" \/>\t\t\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t<\/div>\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-22-12176-g002.jpg\" data-rel=\"prettyPhoto[image_gallery_pretty_photo-467]\" title=\"&lt;strong&gt;Figure 02&lt;\/strong&gt; The ten most abundant Gene Ontology terms identified in PRGF and AS formulations, and two of the processes that were only found in AS formulation, which were related to extracellular matrix organization and immune response.\">\n\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.btitrainingcenter.com\/wp-content\/uploads\/2021\/08\/ijms-22-12176-g002-200x200.jpg\" alt=\"\" width=\"200\" height=\"200\" \/>\t\t\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t<\/div>\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-22-12176-g003.jpg\" data-rel=\"prettyPhoto[image_gallery_pretty_photo-467]\" title=\"&lt;strong&gt;Figure 03&lt;\/strong&gt; Canonical pathway analysis of the differentially expressed proteins in HK cells after treatment with PRGF or AS.
