Summary
Generating mesenchymal stem/stromal cells (MSCs) from human induced pluripotent stem cells (iPSCs) is crucial for therapy. This study optimizes MSC production from iPSCs using embryoid bodies and TGF-β1, achieving high efficiency and cell stability.
Area of Science:
- Stem cell biology
- Regenerative medicine
- Cell therapy
Background:
- Human induced pluripotent stem cells (iPSCs) can be differentiated into various cell types.
- Mesenchymal stem/stromal cells (MSCs) are valuable for therapeutic applications.
- Current methods for deriving MSCs from iPSCs have low efficiency.
Purpose of the Study:
- To develop an optimized protocol for efficient MSC derivation from human iPSCs.
- To improve the yield and characteristics of iPSC-derived MSCs for therapeutic use.
Main Methods:
- Generation of embryoid bodies (EBs) from human iPSCs.
- Treatment of EBs with transforming growth factor beta 1 (TGF-β1).
- Purification of MSCs based on CD73, CD105, and CD90 marker expression.
Main Results:
- Achieved high-efficiency production of MSCs from human iPSCs.
- Confirmed MSC characteristics after multiple passages.
- Demonstrated the therapeutic potential of iPSC-derived MSCs.
Conclusions:
- The optimized protocol significantly enhances MSC derivation from iPSCs.
- iPSC-derived MSCs maintain their therapeutic properties upon expansion.
- This method provides a renewable and efficient source of clinical-grade MSCs.

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.

Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

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).

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...

Stem cells are undifferentiated cells with extensive self-renewal properties that help them maintain their population during the fetal and adult stages of life. They can specialize in all cell types of the human body. However, their differential potential may vary and can be classified into five types. Stem cells can be (1) Totipotent, (2) Pluripotent, (3) Multipotent, (4) Oligopotent, and (5) Unipotent. Each stem cell has a specific origin; the fertilized egg or zygote is a totipotent cell and...
