CTBS Tissue Processing & Preservation — Questions and Answers
Question 1: What is the primary goal of tissue processing in banking?
- To speed up tissue storage.
- To preserve tissue quality and sterility (Correct answer)
- To reduce tissue preservation costs.
- To alter tissue composition.
Correct answer: To preserve tissue quality and sterility
The primary goal of tissue processing in banking is to meticulously prepare donated tissues to maintain their biological integrity, functionality, and sterility for future use. This involves cleaning, shaping, and often sterilizing the tissue, while also ensuring it remains free from contamination. Effective processing is crucial for successful transplantation and minimizing risks to recipients.
Question 2: Which of the following methods is commonly used for preserving tissues in tissue banking?
- Using chemical preservatives.
- Freezing, cryopreservation, and lyophilization (Correct answer)
- Storing tissues at room temperature.
- Using radiation.
Correct answer: Freezing, cryopreservation, and lyophilization
Common methods for preserving tissues in tissue banking are designed to maintain tissue viability and integrity over extended periods. Freezing involves storing tissues at very low temperatures, while cryopreservation uses extremely low temperatures (often with cryoprotectants) to halt biological activity. Lyophilization, or freeze-drying, removes water from the tissue, allowing for room temperature storage. Each method is chosen based on the specific tissue type and its intended use.
