In-vitro Mutagenesis

In-vitro Mutagenesis

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

IR Frequency Region: X–H Stretching

IR Frequency Region: X–H Stretching

In IR spectroscopy, signals produced by the X−H bonds (such as C−H, O−H, or N−H) can be observed in the frequency range of 2700–4000 cm–1. The C−H stretching vibration forms sharp bands in the region 2850–3000 cm–1. The presence of the O−H stretching vibration leads to the forming of an absorption band in the frequency range 3650–3200 cm−1. At the same time, N−H stretching can be confirmed by absorption bands in...

Fixed Action Patterns

Fixed Action Patterns

A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Hair Cells

Hair Cells

Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here.

IR Frequency Region: Alkyne and Nitrile Stretching

IR Frequency Region: Alkyne and Nitrile Stretching

Both alkyne (C≡C) and nitrile (C≡N) functional groups contain triple bonds and show stretching absorptions around the wavenumber range of 2100 to 2300 cm−1 in the diagnostic region of the IR spectra.
Comparing the stretching vibrational frequency of C≡C triple bonds with that of double and single bonds, it is evident that C≡C triple bonds exhibit a higher stretching frequency than C=C double and C–C single bonds. Similarly, the C≡N triple bond...

Area of Science:

Biotechnology
Cell Biology
Biomedical Engineering

Background:

Mechanotransduction, the cellular response to mechanical stimuli, is crucial for cell homeostasis and alignment.
Existing methods for studying mechanical stimuli on cells often lack the ability to engineer patterned cell cultures.
Controlled cell alignment is vital for various biological applications, including tissue engineering.

Purpose of the Study:

To introduce a novel pneumatically actuated cell stretching array for inducing controlled cell alignment.
To demonstrate the capability of the system in achieving predefined cellular alignment patterns.
To validate the platform's compatibility with standard laboratory formats and its effectiveness with fibroblast cells.

Main Methods:

Development of a 4x2 pneumatically actuated cell stretching array capable of applying cyclic normal strains.
Utilisation of a ring-shaped strain pattern to induce circumferential cellular alignment.
Characterisation of the platform's design, simulation, and experimental validation using fibroblast cells.

Main Results:

The cell stretching platform successfully induced predefined circumferential cellular alignment in fibroblast cells within two hours.
Experimental results showed cytoskeleton reorganisation, with cells aligning perpendicular to the normal strain direction.
The platform's dimensions are compatible with standard F-bottom 96-well plates, ensuring broad applicability.

Conclusions:

The developed cell stretching array is an effective tool for engineering patterned cell cultures with controlled cellular alignment.
This technology holds significant potential for applications in drug screening, 2D mechanobiology, tissue engineering, and regenerative medicine.
