Maintenance of the ES Cell State01:14

Maintenance of the ES Cell State

2.2K
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...

Multipotency of Hematopoietic Stem Cells01:19

Multipotency of Hematopoietic Stem Cells

3.1K
The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...

Source And Potency Of Stem Cells

4.9K
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...

Stem Cell Culture01:17

Stem Cell Culture

5.2K
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...

Regulation of Hematopoietic Stem Cells01:01

Regulation of Hematopoietic Stem Cells

3.2K
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Cellular Differentiation00:57

Cellular Differentiation

2.7K
How does a complex organism such as a human develop from a single cell? It all starts from a single fertilized egg which gives rise to a vast array of cell types, such as nerve cells, muscle cells, and epithelial cells that characterize the adult? Throughout development and adulthood, cellular differentiation leads cells to assume their final morphology and physiology. Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions.
A zygote is a...

Area of Science:

  • Stem cell biology
  • Regenerative medicine
  • Cancer research

Background:

  • Stem cell pools are compartmentalized with distinct subsets showing limited heterogeneity during homeostasis.
  • Stem cell plasticity is evident under stress (injury, aging, cancer), altering phenotype, metabolism, and function.

Purpose of the Study:

  • To explore the regulation of stem cell heterogeneity and plasticity.
  • To investigate the potential of manipulating stem cell behavior for therapeutic applications.
  • To understand the link between stem cell dysregulation and tumor formation.

Main Methods:

  • Review of existing literature on stem cell regulation.
  • Analysis of cell-extrinsic niches and signaling pathways.
  • Examination of cell-intrinsic genetic and epigenetic regulators.

Main Results:

  • Stem cell heterogeneity and plasticity are tightly regulated by complex networks of extrinsic and intrinsic factors.
  • Disruptions in regulation can lead to uncontrolled plasticity and contribute to tumorigenesis.
  • Understanding these mechanisms is key to controlling stem cell behavior.

Conclusions:

  • Manipulating stem cell behavior through understanding heterogeneity and plasticity can revolutionize regenerative medicine.
  • Harnessing stem cell plasticity offers therapeutic promise but requires careful control to prevent adverse effects like cancer.
  • Innovative techniques are needed to fully utilize stem cell potential.
