The cells that eventually form the organ systems of the infant start developing during the embryonic phase of pregnancy, which is generally considered the period from conception to about 8 weeks. This is when the basic structures of the organs begin to form through processes like cell differentiation, migration, and tissue organization.
Differentiation.
Stem cells in the early embryo start differentiating to form the three primary germ layers - ectoderm, mesoderm, and endoderm. These layers give rise to all the tissues and organs in the body.

Stem cells begin the process of differentiation when they receive signals from their environment or neighboring cells. This triggers them to start developing into specific cell types with specialized functions.

After a few weeks of conception, stem cells begin to differentiate into the organs of the developing embryo, with the formation of the heart being one of the earliest events. Around the third week of gestation, the heart starts to develop from mesodermal stem cells, marking a crucial step in organogenesis. This process sets the foundation for the development of other organs and systems in the body as the embryo continues to grow.
Well, all organs start out as cells, then different cells come together and make tissues. The tissues come together and make organs, which form the organ system!.
The process by which cells become different types of specialized cells is called cell differentiation. During this process, specific genes are turned on or off in a cell to determine its specific structure and function. Cell differentiation allows for the development of different cell types in an organism, each serving a specific purpose.
The greatest amount of differentiation for organ formation in embryo development is most likely to occur during the gastrulation stage. This is when the three primary germ layers - ectoderm, mesoderm, and endoderm - form, leading to the development of various organs and tissues. Organs start to take shape and differentiate as cells become specified for their future roles during this critical stage.
