The peptide's predictable dose-response and extended stability in culture media have made it a preferred growth factor supplement in CHO cell culture, stem cell expansion, and primary cell isolation protocols across hundreds of published studies
Furthermore, they adapt the expression of the protein kinase C (PKC) which is involved in the overexpression of CD1d, a molecule with potential role in keratinocyte-NK-T cell interactions in psoriatic lacerations [46]
