Fig. 4From: Confirmation of plant-derived exosomes as bioactive substances for skin application through comparative analysis of keratinocyte transcriptomeThe identification of genes that are specifically expressed in certain treatment group and the analysis of their gene expression tendency. The genes that showed a specific response to nine groups were selected. The nine groups are as follows: (ginseng [extract, exosome, extract and exosome]), (Green tea [extract, exosome, extract and exosome]), (ginseng and green tea [extract]), (ginseng and green tea [exosome]), and (ginseng and green tea [extract, exosome, extract and exosome]). The unit of the expression value is transcripts per million (TPM), and the value is normalized. Genes that showed fold change of > 3 compared with the control group while the other groups showed fold change of < 2 were selected. Fold change was calculated based on TPM values and is depicted using a color gradient. The list of genes with fold change value of ≥ 3 are presented in Additional file 1: Table S2Back to article page
