MORPHOGENESIS AND EXTRAMEDULLARY HEMOPOESIS IN THE SPLEEN OF THE EASTERN EUROPEAN HEDGEHOG

The objective of the research was to study histological peculiarities of the spleen structure of the East European hedgehog (Erinaceus concolor Linnaeus, 1758) in postnatal ontogenesis. For our investigation, 5 animals in each age group were selected; so 20 hedgehogs were studied in order to determine the extramedullary hematopoiesis. Terminology of the described histological structures of the spleen was used in compliance with the International Histological Nomenclature. For the first time it was found that extramedullary hematopoiesis which arises from the red pulp of the spleen is characteristic of the East European hedgehog inhabiting the territory of the Republic of Belarus.
