Insights

Human breast milk contains stem cells with pluripotent characteristics, offering potential benefits for infant development and regenerative therapies. Further research is crucial to understand their full role and potential applications.

Area of Science:

  • Stem cell biology
  • Human lactation research
  • Infant development

Background:

  • Breast milk offers known benefits, but mechanisms for disease protection and neurodevelopment optimization are unclear.
  • Recent discovery of stem cells in breast milk suggests a role in infant development.

Purpose of the Study:

  • To review and synthesize existing research on the characterization of breast milk stem cells.
  • To identify knowledge gaps and areas for future exploration in breast milk stem cell research.

Main Methods:

  • A literature search was conducted from August to October 2015.
  • Databases searched included CINAHL, PubMed, and reference lists.
  • Nine studies focusing on human breast milk stem cell characterization were included.

Main Results:

  • Research on breast milk stem cells is emerging, with five teams globally publishing studies.
  • Current characterization focuses on stem cells from full-term breast milk.
  • These stem cells exhibit variability between mothers and can differentiate into all three germ layers, indicating pluripotency.

Conclusions:

  • Significant knowledge gaps remain regarding breast milk stem cells.
  • Healthcare professionals should be aware of these cells and ongoing research into infant benefits.
  • Further research is needed to characterize stem cells across lactation stages, in preterm milk, and their roles in infant health and regenerative medicine.

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...

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 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...

Adult Stem Cells01:33

Adult Stem Cells

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...

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...

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.
