Summary
Cellular mechanical properties change with the environment. Nutrient depletion, not pH shifts, primarily alters the viscoelasticity of human leukemia cells (HL-60) as they are cultured.
Area of Science:
- Cellular mechanics
- Biophysics
- Cellular microenvironment
Background:
- Cell mechanical behavior is dynamic and environment-dependent.
- Temperature and chemical stimuli like pH can alter cell structure and mechanical response.
- Cellular mechanical properties can indicate cell state.
Purpose of the Study:
- To investigate the influence of medium consumption on the viscoelastic properties of human leukemia cells (HL-60).
- To determine the primary factor responsible for changes in cellular stiffness during cultivation.
Main Methods:
- Applied dielectrophoretic forces to suspension cells using microelectrodes.
- Analyzed cell stretching on consecutive cultivation days.
- Systematically investigated the effects of pH shifts and nutrient depletion separately.
Main Results:
- Medium consumption significantly affected the viscoelastic properties of HL-60 cells.
- Both pH shifts and culture medium depletion influenced cell deformation over time.
- Cellular stiffness changes were primarily attributed to nutrient depletion.
Conclusions:
- Nutrient depletion is the main driver of altered cellular stiffness in HL-60 cells during cultivation.
- Understanding these mechanical changes is crucial for interpreting cellular states.
- Dielectrophoresis is a viable method for probing cell mechanics in response to environmental factors.

01:12Elastin is Responsible for Tissue Elasticity
Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. The main property of elastin is that it will return to its original shape after being stretched or compressed. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column.
Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel. Dense regular elastic tissue contains elastin fibers and...

01:13Cell-matrix's Response to Mechanical Forces
In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue.

01:26Extracellular Matrix
Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. This extracellular matrix (ECM) is composed of fibrous proteins like collagen, elastin, and fibronectin in a ground substance consisting of interstitial fluid, cell adhesion proteins, and proteoglycans. The proteoglycans form a gel-like material in the spaces between cells and provide hydration, buffering, binding, and force...
01:19The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
