So I am not even close to somebody called an embryologist! I stained a section of mouse embryo E13.5 with my protein of interest. But the problem is now that I am ridiculously confused what my staining tells me. All I can say for sure is that the cartilage primordium is low in expression...
Can someone please guide me through what those arrows actually are? What are those white areas? Bone?
Again sorry I feel like very stupid. But your guidance is much appreciated.
