Modeling disease using three dimensional cell culture: multi-lumen and inverted cyst phenotypes

Area of Science:

• Cell biology
• Developmental biology
• Tissue engineering

Background:

• Three-dimensional (3D) cell culture systems mimic in vivo tissue development.
• These systems are valuable for studying epithelial morphogenesis and disease modeling.
• Understanding epithelial glandular architecture is crucial for disease research.

Purpose of the Study:

• To investigate cellular and genetic alterations leading to abnormal epithelial cyst phenotypes.
• To analyze defects in cell polarity and lumen formation during morphogenesis.
• To correlate aberrant cyst formation with disease patterns.

Main Methods:

• Utilized 3D cell culture models.
• Introduced cellular and genetic alterations.
• Observed and analyzed cyst phenotypes (multi-lumen and inverted cysts).
• Examined cell polarity and lumen formation mechanisms.

Main Results:

• Identified two distinct cyst phenotypes: multi-lumen and inverted cysts.
• Multi-lumen cysts arise from defects in polarity, apical assembly, and lumen clearance.
• Inverted cysts exhibit apical domain misorientation towards the matrix, altering morphogenic cues.
• Both phenotypes show defects in cell polarity and lumen formation.

Conclusions:

• Aberrant epithelial cyst formation (multi-lumen and inverted) is linked to cell polarity and lumen development defects.
• These phenotypes resemble histological patterns observed in various diseases.
• Studying these cyst models provides insights into epithelial disease origins and progression.
• Findings may guide the development of novel therapeutic strategies for epithelial diseases.
