Supravital fluorometric apoptosis detection in a single mouse embryo using lab-on-a-chip

Area of Science:

• Reproductive biology
• Biotechnology
• Medical diagnostics

Background:

• Apoptosis detection is crucial for assessing preimplantation embryo viability.
• Current methods for single embryo apoptosis detection often compromise embryo development.
• Lab-on-a-chip technologies offer potential for advanced embryo analysis.

Purpose of the Study:

• To develop a lab-on-a-chip system for supravital apoptosis detection in single embryos.
• To ensure embryo recovery and maintained developmental capacity after analysis.
• To overcome limitations of existing methods in assessing embryo growth potential.

Main Methods:

• Utilized a lab-on-a-chip device integrated with miniaturized optical instrumentation.
• Performed supravital examination to detect apoptotic blastomeres in single embryos.
• Monitored embryo recovery and subsequent developmental competence post-examination.

Main Results:

• Successfully detected apoptosis in single embryos using the developed lab-on-a-chip system.
• Demonstrated full embryo recovery and maintenance of developmental capacity after the procedure.
• Validated the system's ability to assess embryo growth potential without compromising viability.

Conclusions:

• The presented lab-on-a-chip approach enables non-invasive, supravital apoptosis detection in single embryos.
• This technology preserves embryo developmental potential, offering a significant advancement in preimplantation genetic screening.
• The system provides a reliable tool for accurate assessment of embryo viability and growth potential.
