Summary
This study links human induced pluripotent stem cell (hiPSC) morphology to gene expression, enabling prediction of gene levels from cell images. This offers a practical way to monitor hiPSC purification within specific batches.
Area of Science:
- Stem cell biology
- Bioinformatics
- Cellular imaging
Background:
- Purification of human induced pluripotent stem cells (hiPSCs) is crucial for differentiation into specific cell types.
- Current purification relies on gene expression or morphology, but their relationship is not well understood.
Purpose of the Study:
- To investigate the correlation between hiPSC morphology and gene expression levels.
- To develop a predictive model linking cell morphology to gene expression for purification monitoring.
Main Methods:
- Analysis of live-cell phase-contrast images and mRNA profiles during hiPSC purification.
- Application of unsupervised image feature extraction to build a predictive model.
- Validation of the model using cancer gene expression from tissue images.
Main Results:
- A model was developed to predict gene expression levels from hiPSC morphology.
- Two specific genes were identified as well-predicted by cell morphology in hiPSCs.
- Prediction accuracy was robust within reprogramming batches but affected by batch/donor effects.
Conclusions:
- Cell morphology can serve as a proxy for estimating gene expression levels in hiPSCs.
- The developed model provides a practical method for monitoring hiPSC purification within batches.
- Further research is needed to overcome batch effects for broader applicability.

Somatic to iPS Cell Reprogramming
2.3K
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

Chromatin Modification in iPS Cells
1.7K
Chromatin modification alters gene expression; therefore, scientists can add histone-modifying enzymes, histone variants, and chromatin remodeling complexes to somatic cells to aid reprogramming into pluripotent stem (iPS) cells.
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...

Induced Pluripotent Stem Cells
24.3K
Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...

Methods of Nuclear Reprogramming
1.9K
Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for...
