What are embryoid bodies?
Embryoid bodies are three-dimensional aggregates of stem cells that can differentiate into various cell types.
How does retinoic acid affect neural differentiation?
Retinoic acid promotes the differentiation of embryonic stem cells into neural lineages.
What techniques are used to analyze differentiation?
Immunofluorescence and immunoblotting are used to assess the expression of progenitor cell markers.
Why is tracking differentiation important?
Tracking differentiation helps understand the mechanisms involved and improve protocols for therapeutic applications.
