Life in histology. On the 80th anniversary of Professor A.A. Stadnikov

August 26, 2025 marked the 80th anniversary of the prominent Soviet and Russian histologist, Professor Alexander Abramovich Stadnikov. His whole life is connected with the Orenburg Medical University (institute – academy – university), where he went through all the steps of the career ladder – assistant (since 1971), associate professor (since 1983), head of the department (from 1988 to 2025), since 2025 – professor of the department. At the same time, from 1993 to 2009, he was vice–rector, and in 2009 he served as rector of the Orenburg Medical Academy. His research interests cover a wide range of issues in comparative and evolutionary histology, embryonic and postnatal morphogenesis, neuroendocrine regulation of morphogenesis and regeneration, and the history of histology. A major contribution to cell biology was his research on the relationship between pro- and eukaryotic cells. He created a new direction at the Orenburg Scientific Histological School dedicated to the study of neuroendocrine regulation of cells, tissues and organs. His pioneering research is aimed at clarifying the issues of neuroendocrine regulation of the relationship between pro- and eukaryotes. He has been harmoniously combining his intensive research activities with teaching at Orenburg Medical University for over 50 years. He has earned the respect and love of several generations of students, teachers, and doctors. Alexander Abramovich is an example of a talented scientist and teacher who inspires and makes you believe in your own strength. For students and colleagues, he is a high scientific and moral authority.
