cyclo[arginyl-glycyl-aspartyl-D-phenylalanyl-epsilon-(triphenylphosphonium)-lysyl]

A synthetic cyclic RGD peptide that induces the formation of multicellular tumour spheroids (MTS), which serve as 3D in vitro models that mimic the in vivo tumour environment. Cyclo-RGDfK(TPP) induces self-assembly in certain tumour cell lines via interaction with alpha-5 beta-1 integrins. Moreover, the peptide also initiates the formation of 3D spheroids in several cell lines of both normal and stem cells. Those spheroids are valuable tools for the design of 3D in vitro models, as well as for tissue regeneration experiments. 3D in vitro co-culture models based on normal cells and tumor spheroids formed by cyclic RGD-peptide induced cell self-assembly; R.
