Induced Pluripotent Stem Cells01:13

Induced Pluripotent Stem Cells

28.0K
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...

Induced Pluripotent Stem Cells

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).

Structure and Function of Platelets01:18

Structure and Function of Platelets

3.5K
The cell fragments known as platelets are disc-shaped, with an average diameter of about 3 μm and a thickness of roughly 1 μm. They play a crucial role in the body's vascular clotting system, which also involves plasma proteins, blood cells, and blood vessel tissues.
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...

Embryonic Stem Cells00:58

Embryonic Stem Cells

32.4K
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.

Adult Stem Cells01:33

Adult Stem Cells

33.8K
Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

iPS Cell Differentiation01:22

iPS Cell Differentiation

3.1K
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.

Area of Science:

  • Stem cell biology
  • Hematology
  • Biotechnology

Background:

  • Global platelet shortage poses a healthcare challenge.
  • Human induced pluripotent stem cells (hiPSCs) offer a renewable source for platelet production.
  • Current hiPSC-based platelet production faces limitations in yield, cost, and consistency.

Purpose of the Study:

  • To develop an optimized differentiation scheme (ODS) for enhanced ex vivo platelet production from hiPSCs.
  • To improve the efficiency, yield, and cost-effectiveness of hiPSC-derived platelet generation.

Main Methods:

  • Systematic optimization of culture conditions, including initial cell density, medium composition, and cytokine substitution with small molecules.
  • Enhancement of megakaryocyte (MK) polyploidization using specific small-molecule combinations.
  • Comprehensive evaluation using microscopy, flow cytometry, staining, and electron microscopy.

Main Results:

  • Increased initial embryoid body (EB) cell count accelerated MK production.
  • Serum-free medium with human platelet lysate (HPL) supported MK generation.
  • Small molecules effectively replaced cytokines, and specific combinations enhanced MK maturation.
  • Mature MKs produced functional platelets, shortening differentiation to 19 days.
  • Achieved 1.42 CD41+ MKs and 14.9 platelets per iPSC, with a 58.3% cost reduction.

Conclusions:

  • Established a cost-effective strategy for platelet production from hiPSCs.
  • The optimized method yields functional platelets suitable for therapeutic applications.
  • Potential applications include cell therapy and gene editing, addressing critical healthcare needs.
