Embryo and Spare Parts

Outline

Introduction

In this section, the researcher will discuss how Embryology deals with the development of the organism in the earliest stages prior to metamorphosis, hatching or birth. The term "embryology" originated from the Greek phrase - em bryo, which means "in the shells”. The embryo or fetus is an organism that develops under the cover of the egg shell or inside the mother's body in a specialized organ - the uterus.

Embryos for Spare Parts

Researcher in this section explains the cloning of embryos is the twinning of industrial synthesis in a manner similar to twins naturally. A kava reproduction twin where the fertilized egg splits because of the unknown is made up of identical twins.

Therapeutic Cloning

The technique involves implanting the nucleus of an adult somatic cell into an enucleated oocyte to initiate embryonic development and obtain totipotent cells known as stem cells. Indeed, the embryonic stem cell lines from blastocyst (5th to 7th day after fertilization) are likely to be transplanted without causing rejection by the recipient organism.

Reproductive Cloning

The researcher in this section will discuss the reproductive cloning; it is presented as a modern assisted reproduction technique asexual. Reproductive cloning would be used to an infertile couple or with a genetic disease to have a child without going through sexual reproduction.

Developmental Process

In general within 2 weeks after fertilization, the egg known as the fecundity or the fertilized egg takes 3 to 8 weeks after fertilization which is called the embryo. A new individual from a fertilized egg underwent a series of very complex changes; it is only a brief introduction in the context of embryonic development.

Cleavage and blastocyst

After 26 to 30 hours after fertilization, cleavage was observed. Every 10 to 12 hours of first cleavage, 16 to 32 cells were formed known as morula which then began to reach the uterine cavity. After 4 to 5 days, early formation of the blastocyst and the zona pellucida dissolution disappeared.

Conclusion

Researcher, in conclusion explains that the Embryology is the branch of science which includes the description of morphological changes of the egg fertilized in the body (morphological embryology) and studying their determinism (causal embryology).

Embryo and Spare Parts

Introduction

The Embryology is the branch of science which includes the description of morphological changes of the egg fertilized in the body (morphological embryology) and studying their determinism (causal embryology). The "causal embryology" is more commonly known since the 1990s and the advent of genetic molecular, by the term "developmental biology" which also includes the study of post-embryonic development. Embryogenesis can be divided into three stages; cleavage, gastrulation, and the organogenesis. It is the science of the laws of embryonic development of the embryo (Adeeb, 2012). The term "embryology" originated from the Greek phrase - em bryo, which means "in the shells”. The embryo or fetus is an organism that develops under the cover of the egg shell or inside the mother's body in a specialized organ - the uterus. In humans, the developing organism takes about 8 weeks of embryogenesis; the embryo is called ...
