Adult bone marrow contains stem cells that can become many non-blood cell types. This review examines how these stem cells differentiate into various tissues, crucial for future clinical applications.

Area of Science:

  • Stem cell biology
  • Regenerative medicine
  • Hematology

Background:

  • Bone marrow (BM) is a source of hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs).
  • Recent research suggests adult BM harbors cells with broader differentiation potential beyond blood and mesenchymal lineages.
  • These cells may differentiate into nonhematopoietic cells, including epithelial and muscle cells.

Purpose of the Study:

  • To review experimental evidence on adult bone marrow stem cell plasticity.
  • To investigate the conditions and mechanisms of differentiation into nonhematopoietic cells.
  • To identify bone marrow subpopulations responsible for this multipotent differentiation.

Main Methods:

  • Review of in vitro and in vivo experimental studies.

  • Analysis of experimental methodologies and conditions.
  • Examination of factors influencing stem cell differentiation.

    • Main Results:

    • Adult bone marrow contains stem cells capable of differentiating into diverse nonhematopoietic cell types.
    • Differentiation into epithelial and neural cells has been observed under specific experimental conditions.
    • The necessity of tissue injury for this differentiation and the underlying mechanisms are under investigation.

    Conclusions:

    • Adult bone marrow stem cells exhibit remarkable plasticity, differentiating into multiple nonhematopoietic lineages.
    • Understanding the mechanisms and specific cell populations involved is key to harnessing this potential.
    • Further research is required to fully utilize adult stem cell plasticity for therapeutic purposes.
