WebJan 1, 2007 · The cytoplasm of these Schwann cells contained excess amounts of vacuoles of different sizes and shapes, most of them were membrane-bounded, probably degenerating vacuoles. The cytoplasm did not show many cell organelles. The basal lamina of some of these Schwann cells were well-defined and intact. WebSchwann cells originate from neural crest cells which, during embryonic development, are further differentiated into Schwann cell precursors and immature Schwann cells. After the pro-myelin Schwann cell stage, the mature myelinating and non-myelinating Schwann cells are formed. ... S100 proteins are localized in the cytoplasm and/or nucleus of ...
