The word 'scaffolds' is correct and usable in written English
It is a noun that refers to a temporary structure used to support workers and materials during construction or repair work. One can use the word 'scaffolds' when talking about building or construction, such as: - The workers erected scaffolds around the building to begin the repairs. - The construction team put up scaffolds to reach the top of the skyscraper. - The scaffolds were removed once the building was completed. It can also be used metaphorically to refer to a framework or support system for something, such as: - The new training program provided a scaffolding for employees to develop new skills. - The teacher provided scaffolds for students to understand complex concepts. - The government implemented social programs as scaffolds to support vulnerable communities.
In 2003, the owner of a scaffolding company pleaded guilty to manslaughter after one of his scaffolds collapsed and killed five workers.
So tissue engineers have been pursuing a hybrid approach, developing new scaffolds that combine biological and synthetic aspects.Some nerveConsider an accidentally severed nerve in a hand, for example.
He experimented with tissue scaffolds made by fusing billions of tiny acrylic spheres, filling the gaps with silicone, then dissolving the spheres, leaving just the silicone structure behind.
Pressure was applied to push them out, typically using an automated plunger.Bioprinting is very different to standard tissue-engineering, in which cells are cultured and then seeded onto individual biodegradable moulds or scaffolds whose shapes resemble that of the organ or tissue they are replacing.
In the case of Organovo, scientists do it by formulating the gel so they can dissolve it chemically or physically peel it off.Brian Derby of the University of Manchester and author of a review in Science on printing tissues and scaffolds, emphasises that in some cases it is beneficial to use a scaffold.
Many commercially available scaffolds use material normally found in the human body, harvested from animals or human donors.
Three-dimensional scaffolds are often implanted or injected into the body as part of the process of tissue engineering.
These days, the poles are usually secured with strong nylon straps for safety.Researchers working with scaffolds at a far smaller scale are now exploring the use of similar hybrid structures, made using a combination of biological and synthetic elements.
Because silicone is widely used and well understood, obtaining regulatory approval was relatively simple, says Mr Marshall.Many of the scaffolds that have already been commercialised for wound repair, bone grafts and surgical aids are comparatively simple.
The tubes serve as scaffolds for the cells, which after being printed go through a growing phase in an incubator.
But if it degrades too late, after the cells have made their own structure, the patient may end up with scarring.Dr Atala and his team used to create scaffolds by hand and seeded the cells with a hand-held pipette.
