• To discuss the potential roles of these cells in infant health and gastrointestinal tract colonization.
• To highlight stem cells and probiotic bacteria within breast milk.

Main Methods:

• Literature review of scientific studies on breast milk composition.
• Analysis of research on cellular elements in human milk.
• Synthesis of findings regarding leukocytes, epithelial cells, stem cells, and bacteria.

Main Results:

• Human milk contains leukocytes, epithelial cells, and progenitor/stem cells.
• A diverse microbiome, including potentially probiotic bacteria, is present in breast milk.
• The physiological roles and health implications of these cellular components are under investigation.

Conclusions:

• Breast milk cellular components and microbiome play significant roles in infant development.
• Further research is needed to elucidate the precise functions of these cells and bacteria.
• Understanding breast milk's cellular complexity is crucial for infant health and nutrition science.
