Stem Cell Therapy for Tissue Regeneration01:21

Stem Cell Therapy for Tissue Regeneration

4.3K
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.

Tissue Renewal without Stem Cells

1.9K
After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.
However, failure of such a system...

Mesenchymal Stem Cells01:19

Mesenchymal Stem Cells

5.1K
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...

Area of Science:

  • Biomaterials Science
  • Regenerative Dentistry
  • Dental Pulp Biology

Background:

  • Bioactive molecules found in dentine offer potential for dental regeneration.
  • Dental-pulp capping aims to stimulate tertiary dentine deposition following pulp exposure.
  • Natural biomimetic scaffolds may provide advantages over synthetic materials in dental applications.

Purpose of the Study:

  • To review and appraise current evidence on biomimetic dental-pulp capping.
  • To focus on the role of bioactive molecules sequestered in dentine for pulp regeneration.
  • To identify key molecules and future research directions in biomimetic pulp capping.

Main Methods:

  • Literature review and critical appraisal of existing studies.
  • Focus on transforming growth factors (TGF-βs) and bone morphogenetic proteins (BMPs).
  • Analysis of evidence for biomimetic scaffolds in dental-pulp capping.

Main Results:

  • Transforming growth factor-beta (TGF-β1) and bone morphogenetic proteins (BMP-2, BMP-7) are extensively studied bioactive molecules.
  • Natural biomimetic scaffolds show potential for improved aesthetics, biocompatibility, and success rates.
  • Further research is needed to explore synergistic effects of multiple peptides and tailored scaffold carriers.

Conclusions:

  • Bioactive molecules in dentine, particularly TGF-βs and BMPs, are promising for biomimetic dental-pulp capping.
  • Development of tailored scaffolds and investigation of synergistic molecular actions are crucial next steps.
  • Future in vivo studies must account for the inflammatory pulp environment and compare material efficacy.
