iPS Cell Differentiation01:22

iPS Cell Differentiation

3.3K
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 Culture

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...

Embryonic Stem Cells

Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

Embryonic Stem Cells

Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Stem Cell Therapy for Tissue Regeneration01:21

Stem Cell Therapy for Tissue Regeneration

4.9K
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Induced Pluripotent Stem Cells

6.3K
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).

Area of Science:

  • Regenerative Medicine
  • Immunology
  • Gene Editing

Background:

  • Immune rejection is a major barrier to stem cell transplantation (SCT) in regenerative medicine.
  • Hypoimmunogenic stem cells engineered for universal compatibility are needed.

Purpose of the Study:

  • To review advances in engineering hypoimmunogenic stem cells for universal SCT.
  • To discuss strategies for mitigating risks associated with genome editing and cell expansion.

Main Methods:

  • CRISPR/Cas9 gene editing to remove immune markers (HLA class I/II) and retain immune-tolerant molecules (HLA-E, HLA-G, CD47).
  • Utilizing mesenchymal stem cell-derived exosomes and immune checkpoint modulators (PD-L1) to reduce immune reactions.
  • Employing precision editing platforms like base editing and prime editing to enhance genomic safety.

Main Results:

  • Engineered stem cells demonstrate potential for universal use by evading immune recognition.
  • Exosomes and immune modulators show efficacy in reducing graft-versus-host disease and autoimmune responses.
  • Precision editing tools reduce risks of genomic instability and tumorigenicity.

Conclusions:

  • Advances in gene editing and immunomodulation are enabling safer, universally compatible stem cell therapies.
  • Future research integrating AI, precision editing, and bioprinting will drive innovation in treating intractable diseases.
