Growth and development changes of test tube infants on the twelfth day
IVF refers to the babies who complete fertilization and embryo culture in vitro through artificial assisted reproduction technology. The growth and development process of IVF has gone through many stages, with obvious changes every day. This article will focus on the growth and development of test tube babies on the twelfth day.
Embryonic morphogenesis
On the twelfth day of IVF, the embryo has further developed and its shape is gradually clear. After fertilization, the embryo gradually forms two layers of cell clusters, which are called inner cell cluster and outer cell cluster from the inside out. The inner cell mass will develop into placenta and embryonic tissue, and the outer cell mass will form the outer skin and other organs of the embryo. At this time, the embryo has already had the basic conditions for further development.
During development, the embryo will gradually develop into neural tubes, digestive system, heart, circulatory system and other organs and tissues. The formation of these organs and tissues is essential for the normal development of infants.
At the same time, embryos also face some risks and challenges in the twelfth day of development. Possible problems include embryonic dysplasia, chromosome abnormalities, etc. These factors will have a certain impact on the health of infants.
Embryonic cell differentiation
On the twelfth day of IVF, embryonic cells began to differentiate and different cell tissues gradually formed. Through differentiation, cells will develop into tissues and organs with specific functions and structures.
The differentiation of embryonic cells is a complex and precise process. On the twelfth day, the cells in the inner cell mass began to differentiate into embryonic stem cells and ectodermal cells. Embryonic stem cells can differentiate into various types of cells, such as nerve cells, heart cells, muscle cells, etc; Ectodermal cells are responsible for the formation of placenta and embryonic tissue.
The differentiation of embryonic cells is an important link in the process of embryonic development, which plays a decisive role in the normal growth and development of infants.
Preparation for embryo implantation
On the twelfth day of IVF, the embryo was ready to be implanted into the uterus. The embryo will pass through the decidua, form a superficial position on the endometrium, and begin to absorb nutrients. Before embryo implantation, it is necessary to ensure that the endometrium has the conditions suitable for embryo implantation.
The level of progesterone will also gradually increase at this time to provide sufficient nutrition and support to the embryo. The level of progesterone is crucial for embryo implantation and continued development.
In addition, IVF should follow the doctor's advice during the preparation of embryo implantation, pay attention to maintaining good living habits, and avoid such bad behaviors as overwork, drinking and smoking to ensure the success of embryo implantation.
Factors affecting embryonic development
The embryonic development of IVF is affected by many factors. First of all, maternal nutrition is very important for the development of embryos. Mothers should provide adequate nutrition for embryos through reasonable dietary intake.
Secondly, maternal physiological conditions and immune system will also affect embryonic development. Some immune diseases may have adverse effects on embryos and need timely treatment.
In addition, environmental factors may also have a negative impact on embryonic development. The mother should avoid contact with harmful substances and radiation to ensure the healthy development of the embryo.
Summary
The twelfth day of IVF is a critical stage in the process of embryonic development. The embryo continues to form organs and tissues on this day and is ready for implantation. Embryo differentiation and implantation preparation are two major changes during embryo development. Embryonic development is affected by many factors, including maternal nutritional status, maternal physiological status, immune system and environmental factors. By understanding the changes of IVF on the twelfth day, we can better understand the development process of IVF and take corresponding measures to promote the healthy development of embryos.
