Induction
What is responsible for the rise of muscle from myotomes?
Somites
Which type of stem cells can differentiate into all cell types of an organism, including extraembryonic tissues?
Totipotent stem cells
Where are adult stem cells primarily found in the body?
Within the tissues of children
Which type of potency involves a stem cell's ability to differentiate into various cell types, but does not include extraembryonic tissues?
Pluripotency
What is the main difference between unipotent and multipotent stem cells?
Multipotent stem cells can only differentiate into one cell type.
Where do hematopoietic stem cells primarily function in the body?
In the formation of blood cells

Which type of stem cells are characterized by being very malleable and can be maintained for a long period of time?
Mesenchymal cells
What distinguishes adult stem cells from hematopoietic stem cells in terms of tumorogenicity?

Test your knowledge on how cells acquire positional values and become regionally determined in the body. Explore the concept of cell determination and the activation of genes based on cellular location. Learn about the variations in determination during development and the outcomes of cell transplantation.
