One of the striking features of this degeneration process was the appearance at an early stage of micro glial cells completely covered by myelin, which apparently participated in phago cytosis of degenerating axoplasm and to a small extent of their own myelin covering. Evidence was obtained indicating that the numerous degenerating glial cells seen somewhat later in the degeneration process were derived from these myelin-covered microglial cells. Since glial cells of the type described in the previous study have never been implicated in the process of direct Wallerian degeneration, the possibility exists that they may in fact be characteristic for indirect Wallerian degeneration. However, this possibility cannot be adequately assessed unless our present rather scanty knowledge concerning the early glial reaction during direct Wallerian degeneration is extended. Therefore the present study has been undertaken to examine the ultrastructural changes during direct W allerian dege | | 出版日期 | Book 1974 | | 关键词 | animals; cells; electron | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-642-65867-9 | | isbn_softcover | 978-3-540-06750-4 | | isbn_ebook | 978-3-642-65867-9Series ISSN 0301-5556 Series E-ISSN 2192-7065 | | issn_series | 0301-5556 | | copyright | The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer-Verlag GmbH, DE |
