Periodic Reporting for period 1 - IntraMEMS (Microfluidic platform for intra-operative tumor immunohistochemistry)
Período documentado: 2015-06-01 hasta 2016-11-30
Frozen sections (FS) of tumor samples represent a cornerstone of pathological intraoperative consultation and play an important role in the microscopic analysis of specimens during surgery. Immunohistochemical (IHC) stainings on FS would be of great use during intraoperative consultations, if only the turn-around time was not a limitation. Microfluidic technologies have proven to bring substantial improvement in many fields of diagnostics, though only a few microfluidic devices have been designed to improve the performance of IHC assays. In this work, we show optimization of a complete pan-cytokeratin chromogenic immunostaining protocol on FS using a microfluidic tissue processor, into a protocol taking less than 12 minutes. Our results showed specificity and low levels of background. The dimensions of the microfluidic prototype device are compatible with the space constraints of an intraoperative pathology laboratory. We therefore anticipate that the adoption of microfluidic technologies in the field of surgical pathology can significantly improve the way FSs influence surgical procedures.
