Mechanical loading and the control of stem cell behavior.

Area of Science:

• Biomedical Engineering
• Cell Biology
• Regenerative Medicine

Background:

• Mechanical stimulation is a critical regulator of cellular functions.
• Understanding how mechanical forces impact stem cells is vital for regenerative medicine.

Purpose of the Study:

• To review and discuss the effects of various in vitro mechanical stimulation methods on stem cell behavior.
• To explore how mechanical force influences stemness maintenance and differentiation.

Main Methods:

• A narrative review of English-language articles was conducted.
• Literature search performed on PubMed and Scopus databases.
• Focused on studies investigating the effects of mechanical force on stem cells.

Main Results:

• Cells perceive mechanical stimuli via mechanoreceptors, initiating intracellular signaling.
• Stem cell responses vary based on the type, magnitude, and duration of mechanical stimuli.
• Cell type and differentiation stage significantly influence responses to identical mechanical cues.
• Mechanical applications can modulate stemness and guide differentiation into specific lineages.

Conclusions:

• Mechanical force is a key modulator of stem cell maintenance and differentiation.
• Optimized mechanical force application can precisely control stem cell behavior for targeted applications.
