Source: Kay Stewart, RVT, RLATG, CMAR; Valerie A. Schroeder, RVT, RLATG. University of Notre Dame, IN In 1959 The 3 R's were introduced by W.M.S. Russell and R.L. Burch in their book The Principles of Humane Experimental Technique. The 3 R's are replacement, reduction, and refinement of the use of animals in research. The use of cell lines and tissue cultures that originated from research animals is a replacement technique, as it allows for many experiments to be conducted in vitro. Harvesting...

2012
Electrospun scaffolds can be processed post production for tissue engineering applications. Here we describe methods for spinning complex scaffolds (by consecutive spinning), for making thicker scaffolds (by multi-layering using heat or vapour annealing), for achieving sterility (aseptic production or sterilisation post production) and for achieving appropriate biomechanical properties.

A method to process human mammary surgical discard material is described. Processed tissue, in the form of organoids, can be stored frozen indefinitely or placed in culture for long-term growth. This method enables experimental examination of normal human epithelial cell biology, and the effects of exogenous perturbations.

Cleaning, Sterilization, and Disinfection

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease. Cleaning The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Methods of Sterilization II: Chemical Methods

In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements. Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...
FAQs
Its main effect is to limit microorganisms that could enter or spread during handling. Using sterilized instruments and disinfected work surfaces reduces these opportunities, while aseptic practices help keep the sample from being altered. This matters because contamination can change cellular behavior, compromise results, and weaken confidence in findings.
Tissue quality depends on controlled handling throughout collection, trimming, rinsing, sectioning, and transfer. Maintaining aseptic conditions helps limit contamination, while careful manipulation supports preservation of tissue integrity. The combination is important because a sample can remain visibly usable yet produce less reliable biological or analytical results if handling alters its condition.
In tissue culture, microbial contamination can interfere with cellular behavior and compromise continued study of the sample. During histological analysis, contamination or poor handling can affect the prepared material and the reliability of observations. Sterile tissue processing supports both applications by reducing avoidable changes that might obscure biological features or distort experimental conclusions.
A controlled workflow may begin with tissue collection and continue through trimming, rinsing, sectioning, and transfer. Each step requires appropriate handling so that the sample remains protected as it moves between operations. Coordinating these stages reduces opportunities for microbial contamination while preserving the material needed for culture, examination, or other laboratory studies.
Sterilized instruments and disinfected work surfaces provide the immediate physical controls for processing. Appropriate protective practices add a second layer by helping manage contact with biological material and reducing exposure risks for personnel. Together, these measures create a more controlled working environment and help prevent handling conditions from undermining sample quality or experimental consistency.
The approach is useful whenever tissue quality and low contamination are important, including tissue culture, histological analysis, and related laboratory studies. It helps researchers obtain samples that better retain their intended characteristics, supports more reproducible experiments, and reduces the chance that microbial contamination or handling problems will influence the observed outcome.
