Introduction:
The beginning of Stem Cell research can be dated back to Ernst Neumann, who was appointed professor of pathology at Koenigsberg in 1866 and described in a preliminary communication [5], the presence of nucleated red blood cells in bone marrow (BM) saps. He concluded in his subsequent papers, that during postembryonic life, erythropoiesis and leukopoiesis are taking place in the BM. On the basis of his observation,
Ernst Neumann was the first to postulate the BM as blood forming organ with a common SC for all hematopoietic cells. Zech,N.H., Shkumatov,A. Koestenbauer,S.: Die magic behind stem cells. Journal of Assisted Reproduction and Genetics Vo. 24, Nr. 6 (2007) 208 - 214 |
