The process of implantation is followed by the rapid differentiation of the inner mass of cells of the blastocyst. These cells differentiate into the outer layer of ectoderm and the inner layer of endoderm. Mesoderm arises later.

Implantation is followed by the differentiation of inner cell mass into outer ectoderm and inner endoderm.
Implantation refers to the attachment of the blastocyst (a hollow ball of cells) to the uterine wall. After implantation, the inner cell mass undergoes further differentiation to give rise to the three primary germ layers: ectoderm, mesoderm, and endoderm. These germ layers are the basis for the development of specialized tissues and organs in the embryo.
Explanation:
1. Implantation:
- Implantation occurs around 6-7 days after fertilization when the blastocyst implants into the uterine lining.
- The blastocyst is a structure consisting of an outer layer called the trophoblast and an inner cell mass.
- The trophoblast is responsible for implantation and later forms the placenta, while the inner cell mass gives rise to the embryo.
2. Differentiation of inner cell mass:
- After implantation, the inner cell mass undergoes differentiation to form the three primary germ layers: ectoderm, mesoderm, and endoderm.
- This process is known as gastrulation and occurs during the third week of embryonic development.
3. Ectoderm:
- The ectoderm is the outermost germ layer formed from the differentiation of the inner cell mass.
- It gives rise to various structures, including the skin, hair, nails, nervous system, and sensory organs.
4. Endoderm:
- The endoderm is the innermost germ layer formed from the differentiation of the inner cell mass.
- It gives rise to the lining of the digestive tract, respiratory system, liver, pancreas, and other internal organs.
5. Mesoderm:
- The mesoderm is the middle germ layer formed from the differentiation of the inner cell mass.
- It gives rise to various structures, including the skeletal system, muscles, cardiovascular system, kidneys, and reproductive organs.
In conclusion, implantation is followed by the differentiation of the inner cell mass into the outer ectoderm and inner endoderm. These germ layers play a crucial role in the development of specialized tissues and organs in the embryo.
