PRINS as a method for rapid chromosomal labeling on human spermatozoa

Area of Science:

• Human genetics
• Molecular biology
• Reproductive science

Background:

• Aneuploidies in human spermatozoa can lead to reproductive issues and developmental disorders.
• Accurate and efficient detection methods for sperm aneuploidies are crucial for genetic counseling and reproductive medicine.

Purpose of the Study:

• To evaluate the efficacy of the primer extension reaction, interفراد (PRINS) method for direct in situ labeling of human spermatozoa.
• To determine the speed and reliability of the PRINS technique for detecting specific chromosomal aneuploidies.

Main Methods:

• Human spermatozoa were directly labeled in situ using the PRINS technique.
• PRINS involves annealing specific oligonucleotide primers and primer extension by Taq DNA polymerase.
• Reactions were performed on a programmable temperature cycler, with labeling achieved within a 1-hour timeframe.

Main Results:

• The PRINS method was successfully applied to human spermatozoa.
• Specific primers for chromosomes 13, 16, and 21 were effectively used for labeling.
• The entire labeling process was completed within a 1-hour reaction time.

Conclusions:

• The PRINS method provides a fast and reliable technique for the direct in situ detection of aneuploidies in human spermatozoa.
• This method holds potential for clinical applications in reproductive genetics and diagnostics.
