Neuroblast

Neuroblast (neuroblastus; neuro- + Greek blastos germ, germ) is an undifferentiated precursor cell of nerve cells. Neuroblasts are formed from stem cells during neurogenesis and give rise to neurons and glial cells.

Neuroblasts are characterized by a high level of expression of genes responsible for proliferation and differentiation. They actively divide and migrate to the site of final differentiation. At the same time, neuroblasts undergo morphological changes - they develop processes and form synapses.

Neuroblasts play an important role in the embryogenesis of the nervous system, as well as in neurogenesis in the adult brain. Their damage or death can lead to disturbances in neurogenesis and the development of neurological diseases. Studying the biology of neuroblasts is important for understanding the processes of formation of the nervous system and finding approaches to treating its pathologies.

Introduction

Neuroblasts are cells of the central nervous system that play an important role in the development of nervous tissue. They are the precursors of nerve cells and are part of the neurogenic process. In this article, we will look at the history, functioning and applications of neuroblasts in various fields such as science, medicine and industry.

History of neuroblastic cells

The first mention of neuroblasts was made in the 19th century, when French scientists noticed their presence in the developing embryonic brain. However, it was only after the Japanese scientist Kazuo Tsuroke discovered the way to the growth of neuroblasts along myelin channels in 1935 that a comprehensive study of this cell line began. Since then, it has become the subject of study by many researchers from around the world.
