Summary

The outstanding scientists A. Maximow and A. Friedenstein consecrated their lives to the study of stem cells. A. Maximow created a theory of hematopoiesis and a concept of hematopoietic stem cells, A. Friedenstein discovered mesenchymal stem cells and the hematopoietic microenvironment. The achievement of both researchers inspired other scientists and doctors to develop hematopoietic stem cell transplantation and other methods of cellular therapy as a treatment for a variety of severe diseases.

Keywords: A.J. Friedenstein, A. Maximow, bone marrow, stroma mesenchymal stem cells

Maximow and Friedenstein

Two researchers, Alexander Maximow (1874–1928), and Alexander Friedenstein (1924–1998), are standing out in Russian experimental hematology and, today, their merits are recognized worldwide. They met a rather similar fate. Both of them started their medical carrier in the Military Medical Academy. Their theories on stem cells were far ahead of their time and were met with skepticism. Therefore, the merits of both were underestimated during their lifetime. Finally, the scientific concepts of Maximow and Friedenstein represent an experimental basis for the transplantation of hematopoietic stem cells and for the development of various approaches to cellular therapy and their implications. Cellular therapy is a promising research discipline which has rapidly developed since the last decade. For the history of this field, it is noteworthy today that Maximow postulated a unitary theory of hematopoiesis and a concept of hematopoietic stem cells (HSC), and Friedenstein discovered adult non-hematopoietic stem cells (mesenchymal stem cells, MSC) in bone marrow (BM).

A.J. Friedenstein pioneered the understanding and positive evaluation of Maximow’s heritage: He restored the good name of Maximow in Russia where Maximow was discredited after the revolution of 1917 and his work unfairly forgotten. In the history of histology and hematology in the USSR, Maximow's name had been given a negative connotation when he was mentioned together with a group of other “reactionary” scientists, e.g., A. Weissman, L. Morgan, N. Vavilov et al., which was in fact a great honor for him. It was Friedenstein who studied in detail the main stages of Maximow’s research in Russia, Germany, and the USA, together with Russian and foreign colleagues (M. Tavassoli, D. Rowley) and he can be credited today for having contributed to the restoration of Maximow’s good name by highlighting the great significance of Maximow's fundamental studies in hematology.

Friedenstein's scientific contributions

As a young researcher, A.J. Friedenstein performed studies on the regeneration of skin and bones in Amphibia, especially in vitro culturing of frog transitional epithelium. From 1950 onwards, A.J. Friedenstein worked at the N.F. Gamaleya Institute of Epidemiology and Microbiology (USSR Academy of Medical Sciences). During this period, he carried out various studies in morphology and microbiology, with a special interest on interactions between the bone and hematopoietic tissues. From 1963 onwards, A.J. Friedenstein was the head of the immunomorphological laboratory, which was run by him for 25 years [4]. He headed studies in cellular disturbances following irradiation, development of approaches to regeneration of hematopoiesis, as well as continuing research in bone tissues. (Please find a list of Friedenstein's publications after the references below.)

A.J. Friedenstein is generally credited with the discovery of MSC. He started his pioneering work about 40 years ago by stating the critical observation that BM in postnatal life is a reservoir of stem cells for mesenchymal tissues. From BM, Friedenstein isolated for the first time adherent, fibroblast-like, clonogenic cells (colony forming unit-fibroblast, CFU-F) with a high replicative capacity in vitro (Friedenstein et al. 1968, 1970, 1974, Keiliss–Borok IV et al. 1971), which was multipotential in that it was able to differentiate into osteoblasts, chondrocytes, adipocytes and hematopoietic supporting stroma when a single CFU-F was re-transplanted in vivo (Friedenstein et al. 1966, 1968, 1974, 1980, 1987).

Collectively, these pioneer studies demonstrated that BM contains a cell population, distinct from HSC that is clonogenic, capable of protracted self-maintenance and differentiation into multiple mesenchymal cell lineages. Accordingly, these cells fulfill the criteria of stem cells (Till and McCuloch 1961).

Several generations of scientists, in particular biologists and medical doctors now working both in Russia and abroad got their basic knowledge from the books of A.J. Friedenstein and continue his studies in mesenchymal stem cells for various goals. A lot of scientists belong to A.J. Friedenstein’s scientific school: R.K. Chailakhyan, N.V. Latsinik, Yu.V. Gerasimov, A.I. Kuralesova, A.G. Konoplannikov and others. In the West, Friedenstein's findings were important for research undertaken by, e.g., T.M. Dexter [5]. Those who remember the personal contacts and discussions with Friedenstein appreciate today that the real depth of his mind lay in his predictions on the role of mesenchymal cells. In his detailed studies he cooperated with leading Russian traumatologists, including G.A. Ilisarov, a professor at the Academy of Medical Sciences of the USSR (RAMN). Together they made a pioneering proposal on applications of mesenchymal cells in clinical settings.

The life of A.J. Friedenstein was full of research endeavours, which he acted on without any compromise. His devotedness in defending his scientific viewpoints and ideas today may serve as a good example for young researchers and scientists.
