Secretome characterization uses targeted assays such as ELISA panels for specific growth factors and cytokines. For Bio Xsomes, the supplier reports a growth-factor and cytokine panel as analytical findings only, not as a description of clinical effect.
Secretome composition varies by source cell or tissue type, culture conditions, and processing method, which is why published characterization data is specific to a given source and process rather than generalizable across all perinatal tissue or cell line-derived products.
A secretome or growth-factor panel describes what analytical testing found in a sample, reported as present or at a measured concentration. It is not a statement about physiological effect. Ask the supplier for the underlying characterization method and data behind any such panel, separate from any statement about use.
A secretome panel describes measured composition, not function, which is the distinction buyers should maintain when reviewing supplier characterization sheets.
