Uptake and localisation of mTHPC (Foscan) and its 14C-labelled form in normal and tumour tissues of the hamster squamous cell carcinoma model: a comparative study.

Blant SA, Glanzmann TM, Ballini JP, Wagnières G, van den Bergh H, Monnier P - Br. J. Cancer (2002)

Bottom Line: The majority of mTHPC was found at around 48 h in smooth muscle and at 96 h in healthy cheek pouch mucosa and early malignant lesions.Soon after the injection, a significant selectivity was noted for advanced squamous cell carcinoma as compared to healthy cheek pouch mucosa or striated muscle.A significant difference in mTHPC localisation and quantity was also observed between striated and smooth muscle during the first 48 h following the injection.

The comparative pharmacokinetics of mTHPC in the liver and kidney using in situ LIFS (A), extraction of 14C-labelled mTHPC (B) and ex vivo FM (C). Fluorescence photomicrographs and corresponding HE stains show the high fluorescence intensity, uniform in liver parenchyma (D) and kidney glomerulus (white areas), while a low dye amount was observed in proximal and distal tubes of kidney parenchyma (dark area) soon (24 h) after mTHPC administration (E). Scale: the bar in the right bottom corner represents 20 μm.

Mentions: The comparative pharmacokinetics of mTHPC in serum and vascular endothelium by means of in situ LIFS (A), extraction of 14C-labelled mTHPC (B) and ex vivo FM (C). The fluorescence photomicrograph and corresponding HE staining of the blood vessel wall 48 h after mTHPC administration shows a much higher fluorescence intensity in blood vessel (V) endothelium as in adjacent structures such as fibro-connective tissue (FC) of lamina propria and striated muscle (SM) (D). Scale: the bar in the right bottom corner represents 20 μm.
