How to Collect Tissue Samples for Biomedical Research: 6 Steps

For the success of human tissue research, reputable biobanks offer both normal, malignant, and disease-state tissue samples, including breast, cervical, lung, muscle, uterine, and more. To achieve the highest standards in tissue sample collection, 6 key practices should be followed. These practices ensure that the samples remain viable for research and diagnostic purposes, maintaining their integrity from the point of collection to their final use: 

Step 1: Preparation and Planning

Before collecting tissue samples, it’s essential to plan and prepare thoroughly. This includes understanding the specific requirements of the study or diagnostic tests, such as the type of tissue needed, the size of the sample, and the preservation method required. 

Step 2: Sterilization and Hygiene

Proper planning also involves ensuring that all necessary tools and materials are sterilized and ready for use. All instruments used in the collection process must be thoroughly sterilized to prevent contamination. Additionally, the environment in which the samples are collected should be clean and controlled. This is particularly important in surgical settings where tissue samples are often obtained. 

Step 3: Minimizing Handling

Excessive handling of tissue samples can lead to degradation and contamination. To maintain sample integrity, especially in control samples, it’s crucial to handle tissue samples as little as possible. When handling is necessary, it should be done with care and precision, using tools such as forceps to avoid direct contact with the simple. Minimizing handling is a key principle in tissue sample collection, helping to reserve the biological materials for accurate analysis. 

Step 4: Rapid Preservation

Once the tissue sample has been collected, it must be preserved quickly to prevent degradation. Depending on the type of tissue and the intended use, different preservation methods may be used, such as freezing or embedding in paraffin. Rapid preservation is essential for maintaining the molecular structure of the tissue, which is critical for downstream applications like genetic sequencing or protein analysis. FFPE tissue samples are sustained using a rapid preservation method that is widely recognized for its ability to maintain tissue integrity over long periods. 

Step 5: Accurate Labeling and Documentation

Proper labeling and documentation are vital for tracking tissue samples and ensuring their correct use in research or diagnostics. Each sample should be labeled with detailed information, including the date of collection, the type of tissue, and any relevant patient data (in compliance with privacy regulations). Documentation should also include a clear record of the collection process, storage conditions, and any handling procedures. Accurate labeling and documentation are essential for the success of any study or diagnostic procedure involving tissue samples. 

Step 6: Ethical Considerations

Lastly, ethical considerations are paramount in collecting tissue samples. Before collection, patients or donors must provide informed consent, ensuring they understand the purpose of the collection and how their tissue will be used. Additionally, all tissue sample collection processes should comply with local, national, and international regulations governing the use of human biological materials.
