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

On August 26, 2025, Professor Aleksandr A. Stadnikov, a prominent Soviet and Russian histologist, celebrated his 80th birthday. His entire career has been connected with the Orenburg Medical University (formerly Institute—Academy—University), where he rose through all stages of the academic hierarchy, from assistant (since 1971), to associate professor (since 1983), and later Head of the Department of Histology (1988–2025). In parallel, between 1993 and 2009, Professor Stadnikov served as vice-rector, and in 2009 as acting rector of the Orenburg Medical Academy. Since 2025, he has continued his work as a professor at the Department of Histology. His research interests include comparative and evolutionary histology, embryonic and postnatal morphogenesis, neuroendocrine regulation of morphogenesis and regeneration, and the history of histology. His research into the interactions between prokaryotic and eukaryotic cells has made a significant contribution to cell biology. Professor Stadnikov established a new direction within the Orenburg school of histology, focusing on neuroendocrine regulation of cells, tissues, and organs. His pioneering studies clarified the role of neuroendocrine regulation in the interactions between prokaryotes and eukaryotes. For more than 50 years, Professor Stadnikov has taught at Orenburg Medical University while conducting extensive research. He has earned the respect and admiration of generations of students, teachers, and physicians. Professor Stadnikov is an example of a gifted scientist and educator who motivates and empowers others.
