Induced Pluripotent Stem Cells01:13

Induced Pluripotent Stem Cells

28.1K
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).

Steel Manufacturing01:26

Steel Manufacturing

1.5K
Steel manufacturing is a multi-stage process that begins by smelting iron ore into cast iron in a blast furnace. This initial stage involves layering iron ore with coke, a type of fuel, and crushed limestone within the furnace. The coke is ignited with a high volume of air, leading to the creation of carbon monoxide, which acts to reduce the iron ore to pure iron.
During this smelting process, limestone plays a crucial role by forming slag. Slag captures impurities within the molten iron, such...

Formulation and Manufacturing Process: Physical Attributes of Generic Tablets and Capsules

340
Bioequivalence in generic drugs, such as tablets and capsules, refers to their pharmaceutical equivalence to the brand-name counterparts. However, for therapeutic equivalence, manufacturers must also consider physical attributes like size, shape, and weight (FDA Guidance for Industry, December 2003). Discrepancies in these aspects could impact patient compliance and cause medication errors. For instance, swallowing difficulties, often experienced with larger tablets or capsules, can lead to...

Embryonic Stem Cells00:58

Embryonic Stem Cells

32.6K
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.

Manufacture of Concrete Masonry Units01:27

Manufacture of Concrete Masonry Units

421
The process of manufacturing concrete masonry units begins by mixing stiff concrete composed of Portland cement, aggregates, and water. This mixture is then poured into metal molds. To ensure the concrete settles uniformly and to avoid separation of its components, the mixture in the molds is subjected to vibration. Shortly after, the still-wet blocks are removed from the molds and placed on racks.
These wet blocks are then transported for curing, which can occur in one of two environments: a...

Area of Science:

  • Regenerative Medicine
  • Stem Cell Biology
  • Cell Therapy

Background:

  • Human induced pluripotent stem cells (iPSCs) offer promise for regenerative medicine and cell replacement therapies.
  • Clinical application of iPSCs necessitates high-quality, specialized cells derived from robust differentiation protocols.
  • Master cell banks (MCBs) of iPSCs have been manufactured under current good manufacturing practices (cGMPs).

Purpose of the Study:

  • To evaluate the clinical potential of cGMP-manufactured human iPSCs.
  • To demonstrate differentiation into all three embryonic germ layers (ectoderm, endoderm, mesoderm).
  • To confirm the manufacturing process is not lineage-biased.

Main Methods:

  • cGMP-compliant manufacturing of human iPSC master cell banks.
  • Directed differentiation of iPSCs into specific cell lineages.
  • Characterization of differentiated cells for lineage-specific markers and morphology.

Main Results:

  • Successful differentiation of cGMP-iPSCs into ectodermal (neural stem cells), endodermal (definitive endoderm), and mesodermal (cardiomyocytes) derivatives.
  • Demonstrated that the iPSC manufacturing and culture system is not biased towards any specific cell lineage.
  • Specialized cells exhibited expected morphological and cellular characteristics.

Conclusions:

  • cGMP-compliant human iPSCs possess the potential for broad clinical applications.
  • The developed iPSC manufacturing process supports the generation of diverse, clinically relevant cell types.
  • These findings support the advancement of iPSC-based therapies for various medical conditions.
