MPEG1 and Langer mesomelic dysplasia: MDA-MB-231 TNBC cells labeled with GFP have been injected into the vasculature of transparent transgenic Tg (mpeg1:mCherry) zebrafish embryos and then studied for extravasation, metastasis, and immune system interaction [43], but to our knowledge, injection of TNBC cells into ventricle structures associated with LMD and their study has not been attempted.
