Which characteristic is associated with stem cells?
Self-renewal
Limited differentiation
Terminal differentiation
Restricted proliferation
What does pluripotency refer to in stem cell biology?
Ability to differentiate into cells of all three germ layers
Ability to self-renew indefinitely
Ability to only form one cell type
Ability to resist aging
Which term describes the local cellular environment that regulates stem cell behavior?
Stem cell niche
Extracellular matrix
Growth factor pool
Cellular signaling cascade
What is a principal advantage of applying engineering approaches in stem cell research?
Enabling quantitative analysis and precise control of cell behavior
Limiting experiments to qualitative observations only
Focusing exclusively on clinical trial designs
Avoiding mathematical modeling in research
What role does the extracellular matrix (ECM) play in stem cell microenvironments?
Provides structural support and signals for cellular regulation
Acts solely as a physical barrier
Inhibits stem cell proliferation
Prevents cell-to-cell communication
How do transcription factors influence stem cell fate?
By regulating gene expression networks that determine cell differentiation
By degrading extracellular matrix proteins
By altering membrane fluidity
By exclusively promoting cell apoptosis
Which gene editing technology has significantly advanced the study of stem cell genetics?
CRISPR-Cas9 system
RNA interference
Fluorescence in situ hybridization
Spectrophotometry
How does the stiffness of the extracellular matrix (ECM) affect stem cell differentiation?
It influences lineage commitment by modulating mechanotransduction signals
It solely enhances cell proliferation without affecting differentiation
It has no measurable impact on stem cell behavior
It only determines cell shape without functional consequences
Which factor is critical for maintaining the undifferentiated state of mouse embryonic stem cells in vitro?
Leukemia Inhibitory Factor (LIF)
Bone Morphogenetic Protein (BMP)
Epidermal Growth Factor (EGF)
Insulin-like Growth Factor (IGF)
What advantage do engineered hydrogels provide in the study of stem cell microenvironments?
They mimic the 3D architecture of tissues and allow controlled manipulation of properties
They serve only as inert physical supports for cells
They limit the incorporation of growth factors
They promote random cell aggregation without structure
How are induced pluripotent stem cells (iPSCs) typically generated from somatic cells?
By introducing defined reprogramming factors like Oct4, Sox2, Klf4, and c-Myc
Through spontaneous reversion without external intervention
By fusion of two somatic cells
By inhibiting all gene expression in the cell
Which application of stem cells is directly associated with the repair or replacement of damaged tissues?
Regenerative medicine
Drug metabolism profiling
Cancer diagnostics
Neural network simulation
In stem cell microenvironments, what role do growth factors play?
They provide biochemical signals that guide proliferation and differentiation
They determine the physical shape of the extracellular matrix only
They cause cellular apoptosis exclusively
They play no role in influencing cell fate
What challenge is associated with prolonged in vitro expansion of stem cells?
Accumulation of genetic mutations
Immediate spontaneous differentiation
Excessive cell death due to over-nutrition
Enhanced resistance to any form of stress
Which engineering strategy offers precise control over the spatial arrangement of stem cells in tissue constructs?
Bioprinting
Electroporation
Magnetic resonance imaging (MRI)
Spectrophotometry
