Protein distribution of hMADS cell secretome. A. hMADS cell secretome is represented using a pie chart in three main groups: secreted proteins with signal peptide (sp, dashed area), secreted proteins without signal peptide (ex, white area) and intracellular proteins (in, dark area). The percentage of the proteins present in each group is reported in the scheme. One hundred per cent is referred to a total number of 73 identified proteins. B. Venn diagram of proteins expressed under the different culture conditions; n represents protein number in each condition.
