Stem Cell Culture01:17

Stem Cell Culture

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...
Mesenchymal Stem Cells01:19

Mesenchymal Stem Cells

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 access...
Embryonic Stem Cells00:58

Embryonic Stem Cells

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.
Embryonic Stem Cells00:57

Embryonic Stem Cells

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...
iPS Cell Differentiation01:22

iPS Cell Differentiation

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.
Stem Cell Therapy for Tissue Regeneration01:21

Stem Cell Therapy for Tissue Regeneration

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.

Area of Science:

  • Regenerative Medicine
  • Orthopedic Research
  • Stem Cell Biology

Background:

  • Current orthopedic treatments for osteo-degenerative diseases like osteoporosis primarily involve antiresorptive therapies, anabolic medications, or surgical interventions, which manage symptoms but do not address the root cause.
  • The limitations of existing treatments highlight a significant need for regenerative therapies capable of addressing the underlying dysregulation of bone tissue.
  • Stem cells hold the potential to revolutionize treatment by regenerating damaged tissues and offering a curative approach to bone diseases.

Purpose of the Study:

  • To review and synthesize research on the successful in vitro generation of osteoblasts, osteoclasts, and chondrocytes from stem cells.
  • To collate findings from animal models testing the function of these laboratory-generated bone cells.
  • To emphasize the potential and challenges of using embryonic stem cells in clinical applications for bone regeneration.

Main Methods:

  • Assembly of reports detailing the differentiation of stem cells into key bone cell types (osteoblasts, osteoclasts, chondrocytes) in culture.
  • Review and collation of studies utilizing animal models to assess the in vivo functionality of stem cell-derived bone cells.
  • Focus on embryonic stem cells, analyzing their pluripotency and associated challenges for clinical translation.

Main Results:

  • Demonstrated success in generating osteoblasts, osteoclasts, and chondrocytes from stem cells in vitro.
  • Evidence from animal studies supporting the functional capacity of these engineered cells in bone regeneration contexts.
  • Identification of embryonic stem cells as highly versatile but challenging for clinical implementation due to pluripotency.
