rosehip neuron noun [C]
UK /ˌrəʊz.hɪp.ˈnjʊə.rɒn/ US /ˌroʊz.hɪp.ˈnʊr.ɑːn/
a type of human brain cell with a distinctive appearance that looks similar to a rosehip (the fruit of the rose plant)
One reason rosehip neurons eluded neuroscientists for so long is likely because the cells are so rare in the brain, Bakken said. Another reason, he added, is because human brain tissue is difficult for scientists to obtain for study. Indeed, in the study, the researchers examined only one layer of the brain. It’s possible, however, that rosehip neurons could be found in other layers, too, Bakken said.

scutoid noun [C]
UK /ˈskjuː.tɔɪd/ US /ˈskuː.tɔɪd/
a three-dimensional shape found in skin cells
What matters is that mathematicians had never before conceived of the scutoid, much less given it a name. What matters even more is that scutoids turn out to be everywhere, especially in living things. The shape, however odd, is a building block of multicellular organisms; complex life might never have emerged on Earth without it.

interstitium noun [C]
UK /ɪn.təˈstɪʃ.əm/ US /ɪn.tɚˈstɪʃ.əm/
a human organ made up of spaces filled with fluid situated in and between tissue and other organs
Remarkably, the interstitium had previously gone unnoticed despite being one of the largest organs in the human body … The researchers realised traditional methods for examining body tissues had missed the interstitium because the “fixing” method for assembling medical microscope slides involves draining away fluid – therefore destroying the organ’s structure.
