FFPE Human Tissue Procurement: 5 Best Practices

Formalin-fixed paraffin-embedded (FFPE) tissue samples play a vital role in medical research, diagnostics, and molecular studies. These samples are carefully preserved to maintain their structural and molecular integrity, enabling precise analysis. However, the success of any research or clinical project hinges on the quality of the tissue sample procured. In this guide, we’ll explore 5 of the best practices for tissue procurement, focussing on FFPE human tissue procurement.

What Is Tissue Procurement?

Tissue procurement refers to the systematic process of acquiring biological tissue samples for research, diagnostic, or therapeutic purposes. This process involves collecting, preserving, and preparing samples to ensure their integrity and usability in various applications. In the context of FFPE human tissue procurement, the focus is on preserving human tissue to retain its cellular structure and molecular composition for long-term storage and analysis.

High-quality tissue procurement is critical for the success of studies involving molecular diagnostics, histopathology, cancer research, drug development, and biomarker identification. The process requires strict adherence to ethical guidelines, proper handling techniques, and advanced preservation methods.

5 Best Practices for FFPE Human Tissue Procurement

Properly procuring FFPE human tissue samples requires adherence to rigorous protocols. Below, we’ll outline the key practices necessary to ensure the highest quality and integrity of these essential materials.

1. Ethical Compliance and Donor Consent

The foundation of any tissue procurement program is ethical compliance. Ensure that all samples are collected with the informed consent of donors, following guidelines set by institutional review boards (IRBs) and regulatory bodies. Transparency in communicating the purpose of tissue collection and the intended use of samples builds trust and ensures ethical integrity.

2. Standardized Collection Protocols

Consistency is key to obtaining reliable FFPE samples. Implement standardized collection protocols that define the following:

Tissue Collection: Use sterile instruments and follow aseptic techniques to prevent contamination.
Fixation Process: Promptly immerse the tissue in neutral-buffered formalin to preserve cellular integrity. Ensure the tissue thickness is appropriate to facilitate adequate penetration of the fixative.
Paraffin Embedding: Dehydrate the tissue through a graded series of alcohol solutions before embedding it in paraffin wax. This step protects the sample from degrading during storage.

3. Quality Control Measures

Effective tissue procurement involves rigorous quality control to ensure the samples meet research and diagnostic standards. This includes:

Histological Assessment: Evaluate tissue sections for proper fixation and absence of artifacts.
Molecular Testing: Confirm that DNA, RNA, and protein integrity are preserved.
Documentation: Maintain detailed records of sample origin, collection date, and preservation conditions.

4. Storage and Inventory Management

Proper storage conditions are crucial for preserving FFPE samples over extended periods. Store paraffin blocks at room temperature in a dry, dust-free environment. Use digital inventory management systems to track sample location and history, ensuring efficient use and minimizing the risk of sample loss.

5. Adapting to Research Needs

FFPE human tissue procurement should be tailored to meet specific research requirements. Collaborate with researchers to understand their needs, whether it involves obtaining tissue from a particular organ, ensuring compatibility with molecular techniques, or providing annotated clinical data.

3 Common Challenges in Tissue Procurement

While advancements in technology and protocols have greatly improved tissue procurement processes, challenges remain an inherent part of the field. Understanding these challenges is essential for developing strategies to overcome them and ensuring reliable results. Let’s explore 3 of the most common challenges facing researchers and strategies to address them effectively.

1. Tissue Degradation

Delayed fixation or improper storage conditions can lead to tissue degradation, compromising the sample’s usability. Address this by training personnel on best practices and using quality control checks throughout the procurement process.

2. Ethical and Legal Barriers

Navigating the complex landscape of regulations surrounding tissue procurement can be challenging. Work closely with legal and ethical advisors to ensure compliance with local and international guidelines.

3. Sample Contamination

Contamination from external sources or during handling can render samples unusable. Use sterile tools and environments to mitigate this risk.

Overcoming the common challenges in tissue procurement requires a proactive and informed approach. By addressing tissue degradation, adhering to ethical standards, and minimizing contamination risks, researchers and instructions can ensure the reliability of their FFPPE samples. Awareness of and preparedness are key to maintaining the integrity and usability of tissue samples, paving the way for impactful scientific discoveries and advancements.

Advancements in FFPE Tissue Procurement

The evolving landscape of medical science has brought remarkable advancements in FFPE tissue procurement. Leveraging these innovations can enhance the process’s precision and efficiency.

Automated Tissue Processors: Streamline the fixation and embedding process to minimize variability.
Digital Pathology: Use imaging techniques to assess and annotate tissue samples, facilitating remote collaborations.
Biobank Integration: Centralized biobanks provide access to diverse, high-quality FFPE samples for multi-institutional research projects.

The quality of FFPE samples directly impacts the reliability of research outcomes. High-quality tissue procurement ensures consistent sample quality and reduces variability in experimental results. Preserved molecular markers enable precise diagnoses and prognoses. Robust samples provide a solid foundation for discoveries and advancements in medical science.

How to Choose a Reliable Tissue Procurement Partner

Selecting the right partner for FFPE human tissue procurement is critical. Look for an organization with a track record of delivering high-quality samples. Ensure compliance with regulatory guidelines and ethical practices. Choose a partner willing to adapt procurement processes to meet your specific research needs. Also, opt for providers that offer additional services like histological staining, molecular testing, and clinical data annotation.
