Multipotency of Hematopoietic Stem Cells01:19

Multipotency of Hematopoietic Stem Cells

4.2K
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

6.9K
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...

Satellite Stem Cells and Muscular Dystrophy

2.6K
Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...

Embryonic Stem Cells

6.0K
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

33.5K
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

34.5K
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...

Area of Science:

  • Stem cell biology
  • Skeletal biology
  • Hematopoiesis

Background:

  • Skeletal stem cells (SSCs) are found in postnatal bone marrow.
  • SSCs differentiate into cartilage, bone, hematopoietic stroma, and marrow adipocytes.
  • These lineages form the bone-bone marrow organ, linking skeletal and hematopoietic systems.

  • To review the biology of skeletal stem cells.
  • To discuss SSCs within the context of skeletal lineage development and physiology.
  • To anchor the medical applications of SSCs in their fundamental biology.

Main Methods:

  • Review of existing literature on skeletal stem cells.
  • Analysis of SSC differentiation pathways in vivo.
  • Discussion of the bone-bone marrow organ's development and function.

Main Results:

  • SSCs are multipotent stem cells residing in bone marrow.
  • SSC differentiation follows a specific temporal sequence during development.
  • SSCs integrate skeletal and hematopoietic functions.

Conclusions:

  • Skeletal stem cell biology is crucial for understanding skeletal and hematopoietic disorders.
  • Medical applications of SSCs must be grounded in their developmental and physiological roles.
  • Further research into SSCs can lead to novel therapeutic strategies.
