P0-expressing RT4 D6P2T myelinating Schwannoma cells (ATCC® CRL-2768™; [35 (link)]) and non-P0-expressing MDAMB 468 human breast cancer cells (ATCC® HTB-132™) were grown in Dulbecco’s modified Eagle medium (Life Technologies, UK) containing penicillin, streptomycin and foetal calf serum (All BD Biosciences) at 37 °C and 5% CO2.
In line with their use by Whitney et al. [27 (link)], transgenic B6.Cg-Tg(Thy1-YFP)-16Jrs/J (THY-1 YFP) mice were obtained from JAX (the Jackson Laboratory) and were used for ex vivo and in vivo nerve staining and in vivo biodistribution studies (8–15 weeks old). THY-1 YFP mice express spectral variants of GFP (yellow fluorescent protein—YFP; ex 488, em 520) at high levels in motor and sensory neurons. The fluorescent signal in the nerves was used as an internal control for the staining (pattern) of the developed imaging agents. Balb/c nude mice were used as non-fluorescent control.
