Which cells have the developmental potential to generate both an embryo and its supporting extra-embryonic tissues? A. Stem cells restricted to replacing intestinal epithelium B. Cells from the earliest cleavage stages of an animal embryo C. Blood-forming stem…
Which outcome is consistent with the developmental potential of an embryonic pluripotent stem cell? A. It can form only one already specialized blood-cell type B. It must make an entire placenta as well as every embryonic tissue C. It can generate many…
Suggest why pluripotent cells may be more useful here than a lineage-restricted multipotent cell population.
An individual cell separated from a two-cell mammalian embryo can still generate both the embryonic body and the supporting extraembryonic tissues. How is its developmental potential classified? A. Multipotent B. Totipotent C. Unipotent D. Pluripotent
Which statement accurately describes stem-cell potential? A. An adult blood-forming stem cell is multipotent B. A two-cell-stage blastomere is restricted to blood cells C. Every adult skin stem cell is totipotent D. A pluripotent cell can form only one mature…
The diagram shows several products of one adult stem-cell lineage. Which classification and location fit the cell? A. Totipotent; circulating plasma B. Multipotent; bone marrow C. Totipotent; bone marrow D. Pluripotent; mature erythrocyte
A cultured embryonic stem-cell line can form cell types from all three germ layers but cannot by itself form an entire organism with extra-embryonic tissues. How is its developmental potential described? A. Terminally differentiated B. Multipotent within one…
A laboratory needs to generate several distinct specialized cell types. What is an advantage of a pluripotent embryonic stem-cell line over a typical multipotent adult stem-cell population? A. A broader range of differentiated cell types can be produced B.…
