A quest of Vera M. Danchakoff, a pioneer of stem cell research.

Abstract

Vera Mikhailovna Danchakova (1877-1950), also written in English as Danchakoff and in German as Dantschakoff, was the first woman to graduate with a PhD in Russia. She was a person of many interests and a strong passion for teaching and social justice that may have interfered with her pioneering stem cell research and cell biology, which was far ahead of its time. Danchakova significantly contributed to the unitarian theory of haematopoiesis along with its founder Alexander A. Maximow. She studied the origin of blood cells, the differentiation of tissues and organs in the process of embryonic development of animals, the formation of germ cells and the effect of hormones on the development of organisms. She discovered the role of stem cells in the laying of new tissues, the proof of the extragonadal origin of primary germ cells in birds and the development of methods for transplanting tissues into live embryos. She has been named 'the mother of stem cells' for her investigations of progenitors of cells.
