Quiz — Test Your Understanding

Question 1 of 8
What is the defining characteristic of a stem cell according to the text?
  • A. They are found exclusively in human embryos and umbilical cords.
  • B. They are able to reproduce themselves and generate offspring that become differentiated cells.
  • C. They are post-mitotic cells that never divide once an organism reaches adulthood.
  • D. They are specialized cells that can be easily identified by their unique appearance under a microscope.
Question 2 of 8
What is the primary difference between embryonic stem cells (ES cells) and tissue-specific stem cells?
  • A. ES cells only exist naturally in adults, while tissue-specific stem cells are found in embryos.
  • B. ES cells are considered expanding cells, while tissue-specific stem cells are post-mitotic cells.
  • C. ES cells are pluripotent and can form any cell type, whereas tissue-specific stem cells can only produce cells of their origin tissue.
  • D. ES cells are primed for differentiation, while tissue-specific stem cells are strictly in a naive state.
Question 3 of 8
According to the text, where are embryonic stem cells (ES cells) found in nature?
  • A. In the basal layer of the human epidermis.
  • B. In the hematopoietic system of the bone marrow.
  • C. Within the blastocysts of naturally developing human fetuses.
  • D. They do not exist in nature and only exist as tissue cultures in laboratories.
Question 4 of 8
Why have mouse embryonic stem cells been particularly crucial to biomedical science?
  • A. They can be injected into blastocysts to create genetically modified mice for studying human diseases and testing drugs.
  • B. They are the only stem cells that can be easily converted into human iPS cells.
  • C. They are naturally primed for differentiation, making them the only cells suitable for drug screening.
  • D. They do not require immunosuppressive drugs when grafted into human patients.
Question 5 of 8
What is a major medical advantage of induced pluripotent stem (iPS) cells?
  • A. They are significantly cheaper and faster to produce than any other type of stem cell.
  • B. They are patient-specific and an immunological match to the donor, eliminating the need for immunosuppressive drugs.
  • C. They are naturally occurring in the human body's expanding tissues, making them easy to harvest.
  • D. They are the only stem cells capable of acting as post-mitotic cells to repair neurons.
Question 6 of 8
How do post-mitotic cells differ from renewal cells in the human body?
  • A. Post-mitotic cells continually replace tissues, while renewal cells only divide during childhood.
  • B. Post-mitotic cells divide only during childhood, while renewal cells never divide again.
  • C. Post-mitotic cells are found in the epidermis, while renewal cells are found in neurons and muscle fibers.
  • D. Post-mitotic cells never divide again, while renewal cells continually replace the tissues in which they are found.
Question 7 of 8
Which of the following conditions has seen the most success and promise regarding pluripotent cell therapies?
  • A. Severe spinal cord injuries
  • B. Type 1 diabetes
  • C. Age-related macular degeneration (ARMD)
  • D. Parkinson's disease
Question 8 of 8
What lesson can be drawn from the history of hematopoietic stem cell transplantation (HSCT) regarding the future of stem cell therapies?
  • A. Progress is usually rapid once the basic biology of a system is understood.
  • B. There are often long delays between understanding the underlying biology and actually implementing new therapies.
  • C. Stem cell therapies are generally inexpensive to implement once they pass clinical trials.
  • D. Treatments developed from stem cells rarely carry high mortality rates or severe risks.

Stem Cells — Full Chapter Overview

Stem Cells Summary & Overview

Stem Cells (2021) provides an introduction to stem cells – how they’re used by scientists, the therapies that exist today, and what the near future holds. It focuses on the medical and scientific consideration of stem cells and only briefly considers ethical, political, and legal aspects. This “very short introduction” is part of a series of over 650 short introductions covering myriad subjects in every discipline.

Who Should Listen to Stem Cells?

  • Biology buffs
  • Stem cell therapy skeptics and miracle-cure seekers
  • Politicians and businesspeople interested in the future of stem cell applications

About the Author: Jonathan Slack
