Mouse ESC Differentiation to Nkx2.1+ Lung and Thyroid Progenitors

Area of Science:

• Developmental Biology
• Stem Cell Biology
• Regenerative Medicine

Background:

• Pluripotent stem cells offer a valuable model for studying early lung development in vitro.
• Generating specific progenitor populations is crucial for tissue engineering and cell biology research.

Purpose of the Study:

• To establish a detailed protocol for deriving lung and thyroid progenitors from mouse embryonic stem cells (ESCs) or induced pluripotent stem cells (iPSCs).
• To enable the tracking and purification of these progenitors using the Nkx2.1 marker for further studies.

Main Methods:

• Utilizing a published Nkx2.1-GFP knock-in ESC line.
• Employing fluorescence-activated cell sorting (FACS) to isolate Nkx2.1+ progenitors.
• Culturing sorted cells under serum-free conditions for expansion and differentiation.

Main Results:

• Successful generation of lung and thyroid progenitor populations from ESCs and iPSCs.
• Efficient tracking and purification of Nkx2.1+ progenitors via GFP reporter expression.
• Demonstrated ability to expand, differentiate, and mature purified progenitors in vitro.

Conclusions:

• The protocol provides a robust method for generating and purifying lung and thyroid progenitors from stem cells.
• This approach facilitates in vitro modeling of early lung development and provides accessible cells for research applications.
• The use of Nkx2.1-GFP reporter streamlines the isolation of key progenitor populations.
