(6 cards)
1
Q
Hematopoiesis
A
continuous, regulated process of renewal, proliferation, differentiation, and maturation of all blood cell lines
2
Q
Lifespan of mature blood cells
A
120 days +/- 20 days
3
Q
Types of Human Stem Cell
A
Totipotential Stem Cells
Pluripotential Stem Cells
Multipotential Stem Cells
4
Q
Totipotential Stem Cells (Non-Committed)
A
present in the first few hours after ovum is fertilized; most versatile; can develop into any cell type
5
Q
Pluripotential Stem Cells (Non-Committed)
A
present several days after fertilization; can develop into any cell type except fetus
6
Q
Multipotential Stem Cells (Committed)
A
derived from pluripotent stem cells; can be found in adults; limited to specific cell to form tissues
