Nikolay Grigorievich Khlopin: about life and scientific endeavors (devoted to the 120-th anniversary of birth)

In 2017 we will celebrate the 120-th anniversary of the academician N.G. Khlopin's birth who was anoutstanding evolutionary histologist, the author of a basic concept of tissue divergent evolution, the father of a phylogenetic system of tissues. His endeavors were confirmed and further developed in normal morphology and pathomorphology, the concept of cambial reserve and tissue regeneration, when solving issues of transplantation, inflammatory epitheliza-tion, hematopoiesis (blood formation) and oncology. In his works N.G. Khlopin widely used a method of tissue culture in vitro, which in combination with a histological technique became fruitful in studying the histoblastic potency of normal and tumor tissues. N.G. Khlopin established a prominent scientific histologic school in Russia; its main achievements are described in this article. His concepts are fundamental and applied worldwide; they still have a great impact on the development of medical and biological sciences.
