Which of the following is a benefit of using hydrogel in tissue engineering?

Hydrogels are indeed beneficial in tissue engineering primarily because they can be biodegradable. This property allows them to mimic the natural extracellular matrix, facilitating the gradual incorporation of cells and the eventual replacement of the hydrogel material with new tissue. The degradation of biodegradable hydrogels can be tailored to match the rate of tissue growth, ensuring that they provide support and structure during the healing process but do not leave behind foreign materials once they are no longer needed.

Additionally, hydrogels possess a high water content, which is conducive to nutrient and waste transport, further promoting cell viability and function. This feature enhances the overall effectiveness of hydrogels in various applications within tissue engineering, making them a popular choice for scaffolds and drug delivery systems.
