Applications of Developmental Biology, Briefly Describe the Significance of Developmental Biology in

Developmental biology is a discipline with a wide range of application prospects, and the study of germ cell generation and fertilization is the theoretical basis for the development of production and application technologies such as artificial reproduction of animals and plants, genetic breeding, animal embryos and reproductive engineering. The study of the relationship between the mechanism of cell differentiation and the regulation of gene expression on the one hand, morphological pattern formation and biological function is the answer to many medical problems faced by human beings (e.g., cancer.

and organ and tissue culture, which is the basis for the development of emerging medical industry engineering, is also genetic engineering.

Develop into the basis of a full-fledged practical technology. Life sciences that have caused great repercussions around the world for many years.

Research advances are all related to developmental biology, such as mammals in 1997.

Somatic cell cloning technology, 1999 beyond the Human Genome Project.

and stem cell culture technology, which is the world's No. 1 science news.

Since the mid-50s, the discipline of fish developmental biology has taken fish and aquatic economic animals as the research object, not only carried out the research on the basic theory of developmental biology, but also paid great attention to the research on application, always adhered to the principle of scientific research oriented to economic construction, and has been engaged in the research of reproductive physiology and genetic breeding of fish and other aquatic economic animals for a long time, providing a relatively systematic theory and formulating complete technical measures for the artificial reproduction and breeding of fish and turtles, turtles, frogs, etc. It has made a number of theoretical breakthroughs and application achievements, and has won more than 10 national, provincial and ministerial scientific and technological achievement awards, forming a discipline with characteristics, good development trend and certain influence in the country.

Developmental biology is one of the important basic sub-disciplines of biological sciences.

Answer]: The main research object of medical developmental biology is the human body. On the one hand, it studies the morphological and functional changes of the human body from a fertilized egg to a mature fetus, as well as the human body from newborn to aging.

The basis of ontogeny is cell differentiation, the regulation of gene expression is the key to careful cell differentiation, and developmental biology is mainly to study the genetic program and its regulatory mechanism in ontogeny. On the other hand, it also affects various factors of human development and the relationship between abnormal development and disease. The occurrence of diseases is influenced by a combination of genetic and environmental factors.

The study of developmental biology not only involves the normal development mechanism of the human body, but also involves the abnormal development mechanism, which can be used to explain the occurrence mechanism of diseases such as malformations and tumors, realize family planning, eugenics, and improve the quality of human life.
