Mesenchymal Stem Cells01:19

Mesenchymal Stem Cells

4.6K
Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

Stem Cell Culture01:17

Stem Cell Culture

5.1K
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...

Induced Pluripotent Stem Cells

3.9K
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).

Embryonic Stem Cells00:57

Embryonic Stem Cells

3.4K
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...

Stem Cell Therapy for Tissue Regeneration01:21

Stem Cell Therapy for Tissue Regeneration

4.0K
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.

iPS Cell Differentiation01:22

iPS Cell Differentiation

2.6K
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:

  • Hematology
  • Stem Cell Biology
  • Oncology

Background:

  • Acute myeloid leukemia (AML) pathogenesis is extensively studied, focusing on malignant stem cells.
  • Myelodysplastic syndromes (MDS), a precursor to AML, arise from immature malignant stem and progenitor cells (MDS-SCs).
  • Despite research, translating MDS-SC biology into effective therapies remains challenging.

Purpose of the Study:

  • To evaluate the known properties of MDS-SCs.
  • To examine post-transcriptional mechanisms driving MDS pathogenesis at the stem and progenitor cell level.
  • To identify limitations and gaps in MDS-SC characterization and understanding.

Main Methods:

  • Literature review and synthesis of existing research on MDS-SCs.
  • Comparative analysis of MDS-SC properties with leukemia stem cells (LSCs).
  • Evaluation of post-transcriptional regulatory mechanisms in MDS.

Main Results:

  • MDS-SCs are hypothesized to be a reservoir for MDS evolution and progression.
  • Significant gaps exist in understanding MDS-SC biology and vulnerabilities.
  • The properties of MDS-SCs can be partially inferred from LSC characterization.

Conclusions:

  • Further research is needed to fully characterize MDS-SCs and their vulnerabilities.
  • Understanding post-transcriptional mechanisms is crucial for targeting MDS-SCs.
  • Bridging knowledge gaps in MDS-SC biology is essential for developing novel therapeutic strategies.
