2006)—and there still is no comprehensive neural crest fate map for the adult osteocranium in any amphibian. One caveat to these studies is that they did not assess other possible tissue contributions. Thus, whereas a neural crest contribution to five skull bones has been demonstrated unequivocal...

In juvenile and adult fish, we identified numerous established NC derivatives and, in the cranium, we precisely defined the crest/mesoderm interface of the skull roof. We show the NC origin of the opercular bones and of multiple cell types contributing to the barbels, chemosensory organs located...
presumably due to the Mailard reaction13or an effect of endogenous chromophores inside the tissues18. Preventing the Mailard reaction with alpha-thioglycerol might improve transparency. However, the brain inside the skull remained partially opaque, indicating that the skull hindered but did not block ...
in the half-bone sections2.Notably,such conventional methods obscure specific cellular structures,e.g.,neural innervations,that would be better observed with the intact,unsectioned bones.Moreover,histological sectioning could be challenging for many bone tissues,e.g.,vertebral column,skull and limbs...
We have successfully cleared multiple human organs, including kidney, pancreas, heart, lung, spleen and brain, as well as hard tissue like skull. We also describe an advanced volumetric imaging system using a commercial light-sheet fluorescence microscope that can accommodate most human organs and ...
MRI provides detailed pictures of brain and nerve tissues in multiple planes without obstruction by overlying bones. Brain MRI is the procedure of choice for most brain disorders. It provides clear images of the brainstem and posterior brain, which are difficult to view on a CT scan. It is ...
