Summary
Human induced pluripotent stem cells (iPSCs) offer a promising source for kidney cells in regenerative medicine. Advances in directed differentiation are paving the way for clinical applications, though challenges remain in achieving full functionality.
Area of Science:
- Stem cell research
- Regenerative medicine
- Nephrology
Background:
- Human induced pluripotent stem cells (iPSCs) and embryonic stem cells (ESCs) represent a potential source of unlimited cells for renal applications.
- Regenerative medicine aims to utilize these cells for kidney repair and disease modeling.
Purpose of the Study:
- To review recent advancements in the directed differentiation of human iPSCs into kidney lineages.
- To discuss the challenges in generating functional or mature renal cells from human iPSCs for clinical use.
Main Methods:
- Highlighting recent directed differentiation methods from human iPSCs/ESCs.
- Mimicking embryonic kidney development pathways.
- Generating embryonic renal progenitor cells (e.g., metanephric mesenchyme, ureteric bud).
Main Results:
- Directed differentiation protocols can yield renal progenitor cells in vitro.
- These progenitor cells can form renal tubule-like and glomerulus-like structures.
- Functional equivalence and definitive markers for induced renal cells require further verification.
Conclusions:
- Milestones have been achieved in directed differentiation of human iPSCs for renal cell generation.
- Further research is needed to establish definitive markers and functional assays.
- Successful differentiation is crucial for clinical applications like cell replacement therapy and disease modeling.

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...

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

Stem cell research aims to find ways to use stem cells to regenerate and repair cellular damage. Over time, most adult cells undergo the wear and tear of aging and lose their ability to divide and repair themselves. Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and...
