Methods of Nuclear Reprogramming

Methods of Nuclear Reprogramming

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...

Somatic to iPS Cell Reprogramming

Somatic to iPS Cell Reprogramming

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...

Background:

Current methods for generating pluripotent and therapeutic cells require extensive external manipulation, limiting clinical applications.
Automated cell genesis using microscale physical forces and chronological biochemistry offers a promising avenue for enhanced clinical success.

Purpose of the Study:

To design and fabricate nested polysaccharide droplets for automated cell transformation.
To enable swift and efficient cell state evolution (somatic, pluripotent, therapeutic) without laborious external manipulation.

Main Methods:

Fabrication of millimeter-sized nested polysaccharide droplets with cell-sustaining properties.
Infusion of extracellular matrix proteins, reprogramming, and differentiation factors chronologically across droplet space.
In vitro and in vivo testing of cell transformation into germ layer and bone cells.

Main Results:

Demonstrated successful in vitro and in vivo transformation of cells into germ layer and bone cells.
Nested droplets loaded with BMP-2 synthesized mineralized bone tissue plates in cranial non-union defects within 4 weeks.
Showcased sequenced somatic cell reprogramming and differentiation within hydrogel modules without external manipulation.

Conclusions:

Nested polysaccharide droplets provide a novel platform for controlled, automated cell reprogramming and differentiation.
This approach significantly enhances the efficiency and clinical applicability of regenerative medicine strategies.
The developed hydrogel modules create tissue-mimetic microenvironments that promote effective cell state transitions and tissue regeneration.
