Abstract
It is necessary to verify whether nail fold capillaroscopy can be utilized for the early detection of breast cancer. To establish this technology, an animal model was developed, utilizing mice for nail fold observations. Nail fold capillaroscopy revealed a human-like anatomical pattern and facilitated the observation of cellular movement within blood vessels. Injection of MCF-7 or mammary fibroblasts in mice allowed the observation of cellular vibrations using motion microscopy from nail fold. We have named this technology ‘capillary cell motion microscopy.’ Intriguingly, we were able to identify distinct cellular vibrations in the MCF-7 group. Moreover, evaluating its effectiveness in mice with chemically induced cancer revealed higher sensitivity (81%-85%) compared to conventional methods (45%-68%). Capillary cell motion microscopy, operating at 0.5–1.5 Hz, provided clear distinction of tumor cells and demonstrated potential applicability in human subjects. While condition adjustments may be necessary, this method holds promise for noninvasive breast cancer detection through nail fold observations. © The Author(s) 2024.
