The difficulties involved in growing a replacement organ include all of the following, EXCEPT organs are made from many different types of stem cells. usually a biopsy is required to obtain the stem cells, thus resulting in multiple surgeries. the larger the organ, the more complex it is. scientists have not yet figured out how to make biodegradable scaffolds on which to grow the tissues. most organs require other associated tissues, such as specialized nerves and muscles.

scientists have not yet figured out how to make biodegradable scaffolds on which to grow the tissues.

Explanation:

Organs can be defined as specialized body tissues united to perform specific functions in living organisms. Some examples of organs found in humans are brain, bladder, kidney, heart, intestine, eyes, lungs, liver, etc.

For instance, a liver refers to a large, essential organ that is reddish-brown in color which is used to synthesize proteins, secrete bile, and the detoxification of metabolites.

The difficulties involved in growing a replacement organ include all of the aforementioned statements, except scientists have not yet figured out how to make biodegradable scaffolds on which to grow the tissues.

As a result of biotechnology, scientists have been able to develop or create biodegradable scaffolds (carriers) that can be used to grow living tissues because they possess biological properties that are similar to the native extracellular matrix (ECM).
