Background:

Cellular microenvironments critically regulate human pluripotent stem cell (hPSC) functions.
Understanding the interplay between environmental factors (extracellular matrix, soluble factors) and hPSC behavior is limited by current research tools.
A need exists for advanced systems to recapitulate in vivo conditions and assess multifactorial environmental influences on stem cells.

Purpose of the Study:

To develop and validate a combinatorial platform for investigating the impact of environmental factors on hPSC phenotype.
To elucidate the relationship between extracellular matrix properties, cell seeding density, and hPSC self-renewal.
To gain insights into the chemical and physical mechanisms governing stem cell fate decisions.

Main Methods:

Development of a combinatorial platform integrating microfluidic channels and nanofibers.
Application of high-content single-cell analysis for detailed evaluation of stem cell responses.
Systematic variation of extracellular matrix density and composition, and initial cell seeding densities.

Main Results:

The developed platform successfully recapitulates complex cellular microenvironments.
Demonstrated dependence of hPSC short-term self-renewal on extracellular matrix density and composition.
Quantified the influence of initial cell seeding density on hPSC phenotype and self-renewal.

Conclusions:

The combinatorial microfluidic-nanofiber platform enables sophisticated analysis of environmental effects on hPSCs.
This approach provides crucial insights into the mechanisms controlling stem cell fate and self-renewal.
The findings advance the understanding of stem cell behavior in controlled microenvironments for regenerative medicine applications.
