1.2.3 Stem Cells

    Cards (72)

    • What are stem cells capable of self-renewal?
      Dividing and producing more
    • Match the stem cell type with its differentiation ability:
      Totipotent ↔️ All cell types
      Pluripotent ↔️ Most cell types
      Multipotent ↔️ Specialized lineage
    • Committed cells undergo differentiation to become specialized cell types.
    • Pluripotent stem cells can differentiate into most cell types but not all, such as the placenta.
    • What happens to committed cells after stem cells divide through mitosis?
      They differentiate into specialized cells
    • Embryonic stem cells are pluripotent.

      True
    • Induced pluripotent stem cells (iPSCs) are created by reprogramming adult somatic cells using genetic modifications.
    • From which part of the blastocyst are embryonic stem cells derived?
      Inner cell mass
    • The use of embryonic stem cells raises ethical concerns due to the destruction of embryos.

      True
    • Adult stem cells are multipotent
    • How are induced pluripotent stem cells (iPSCs) generated?
      Genetic modification
    • iPSCs regain pluripotency
    • What are the two key properties of stem cells?
      Self-renewal and differentiation
    • What is the term for the ability of stem cells to transform into specialized cells?
      Differentiation
    • Match the stem cell type with its differentiation potential:
      Totipotent ↔️ All cell types
      Pluripotent ↔️ Most cell types
      Multipotent ↔️ Specialized cell types
    • Which type of stem cell has limited differentiation potential within a specific lineage?
      Multipotent
    • What are the two key properties that define stem cells?
      Self-renewal and differentiation
    • Differentiation is the process by which stem cells transform into specialized cell types.
      True
    • Arrange the events in stem cell differentiation:
      1️⃣ Stem cell undergoes mitosis
      2️⃣ Produces more stem cells and committed cells
      3️⃣ Committed cells differentiate
      4️⃣ Become specialized cell types
    • Stem cells have the ability to divide and produce more stem cells, a process known as self-renewal
    • Match the stem cell type with its self-renewal and differentiation capabilities:
      Totipotent ↔️ Unlimited self-renewal, all cell types
      Pluripotent ↔️ Unlimited self-renewal, most cell types
      Multipotent ↔️ Limited self-renewal, specialized cell types

      Adult stem cells ↔️ Specific tissues
      Induced pluripotent stem cells ↔️ Reprogrammed adult cells
    • What is the second key property of stem cells after self-renewal?
      Differentiation

    • What changes occur during the differentiation process of stem cells?
      Gene expression, morphology, behavior
    • Maintenance factors are signaling pathways that keep cells undifferentiated
    • Stem cells can be used to test new drugs for safety and efficacy.

      True
