Have you ever wondered what PGD FISH (Fluorescent in situ hybridization) looks like in action? Let’s break it down! In this fascinating image, we see a human embryo’s DNA highlighted with vibrant colors. The cell has been stained green, and colorful fluorescent probes are attached to specific chromosomes. This technique helps us count chromosomes and determine whether the embryo has the correct chromosomal makeup.
In the image, we should ideally see two bright spots for each chromosome being examined. For instance, those two red spots indicate two copies of chromosome 13, while the yellow ones signify chromosome 22, and so on for chromosomes 16 and 21. It’s a reassuring sign when we see these pairs, as it means the embryo is chromosomally normal for those specific chromosomes. Just a heads up, one green and one yellow spot appear close together, but they’re definitely present!
