Cord Blood Cells for Developmental Toxicology and Environmental Health

Area of Science:

• Toxicology
• Developmental Biology
• Cellular Biology

Background:

• The Tox21 program promotes in vitro testing focusing on toxicological mechanisms.
• Current developmental toxicology methods have limitations in human population relevance.
• Variability in cellular responses to toxicants is crucial for human relevance.

Purpose of the Study:

• To explore the application of in vitro toxicology initiatives in developmental toxicology.
• To address the gap in human relevance by utilizing cord blood cells.
• To propose using donor-specific cord blood cells for developmental toxicology testing.

Main Methods:

• Review of current developmental toxicology approaches.
• Discussion of using umbilical cord blood cells as a non-invasive source.
• Proposal for extending toxicological testing to human fetal/newborn cell collections.

Main Results:

• Identified a gap in the human relevance of current developmental toxicology methods.
• Highlighted umbilical cord blood as a valuable, non-invasive source of fetal/newborn cells.
• Proposed a novel approach to capture cellular response variability in toxicological testing.

Conclusions:

• Umbilical cord blood cells offer a promising avenue for improving developmental toxicology.
• Testing with donor-specific cells can better reflect human variability in toxicological responses.
• This approach can enhance understanding of toxicant effects during vulnerable developmental stages.
